What is the Difference Between Nearsighted and Farsighted?

dad and son with their eyeglasses

Nearsightedness, or myopia, results in blurred vision when the light that the eye sees is focused in front of the retina, rather than directly on it. 

It also occurs when the physical length of the eye is greater than the optical length – the size of your eyes can directly affect your vision. 

For this reason, nearsightedness often develops in rapidly-growing children or teenagers. As they grow, it can progress even further, requiring frequent changes in glasses or contact lenses.

To summarize, a nearsighted person sees nearby objects clearly, while objects in the distance are blurred.

Symptoms:

  • Blurry vision when looking at distant objects.
  • The need to squint or partially close the eyelids to see clearly.
  • Headaches caused by eye strain.
  • Difficulty seeing while driving a vehicle, especially at night.

Nearsightedness is often first detected during childhood and is commonly diagnosed between the early school years through the teens. A child with nearsightedness may:

  • Persistently squint.
  • Need to sit closer to the television, movie screen or the front of the classroom.
  • Seem to be unaware of distant objects.
  • Blink excessively.
  • Rub their eyes frequently.

Farsightedness, or hypermetropia, is the result of light being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak. 

Farsightedness is often present from birth, but children can often tolerate moderate amounts without difficulty and most outgrow the condition. 

A farsighted person sees faraway objects clearly, while objects that are near are blurred.

To summarise, a farsighted person sees far-away objects clearly, while nearby objects are blurred.

Symptoms:

  • Nearby objects may appear blurry.
  • Needing to squint to see clearly.
  • You have eye strain, including burning eyes, and aching in or around the eyes.
  • You experience general eye discomfort or a headache after doing close tasks, such as reading, writing, computer work or drawing, for an extended period of time.

The best ways to counteract the effects of distance-related vision issues are with high-quality glasses and contact lenses, like the huge range available at SmartBuyGlasses.

If you have an eye condition where you experience myopia and hyperopia, multifocal lenses are required. 

These lenses can combine multiple prescription powers so you can see both near and far. Bifocal and multifocal lenses can also be useful for conditions such as presbyopia.

Where is my pupillary distance on my prescription?

Pupillary distance (PD) is the distance between your two pupils. Near PD is the distance between your pupils when you’re looking at an object close by, because your pupils are closer together. You can read all about pupillary distance here in our Optical Centre article

Your pupillary distance is not always mentioned in your prescription, but if it is, it will be indicated by ‘PD’ 

The average PD for adults is 63 mm and the average near PD is 60 mm. Near PD is usually measured as (PD – 3 mm). For children, the average PD is between 42 and 54 mm. 

You can also measure your PD yourself: find out how to do this here.

How To Choose Your Kid’s Reading Glasses

How To Choose Your Kid’s Reading Glasses

How to choose glasses for your child

Choosing the perfect pair of childrens eyeglasses frames can be a stressful ordeal. Having options is great, but when there are so many different frames and lens materials to choose from, it can be overwhelming to say the least. Not to mention, you can’t forget the importance of eye protection, long-term durability, and warranties.

To help you on your quest of finding the right kids prescription glasses, here are a few easy tips and things to think about when finding the perfect pair. Firstly it is important to get a thorough eye exam made by a kids eye doctor to get the right prescription. This then determines the best type of glasses for your needs.

1) Lens Thickness

The thickness of the glasses’ lenses will depend on your child’s eye prescription. Stronger prescriptions need thicker lenses and weaker prescriptions can be corrected easily with thinner lenses. However, thicker lenses tend to be heavier and need to be fitted with frames that can protect them properly.

2) Plastic or metal?

When it comes to frames, both plastic and metal (wire) frames are durable. In recent years, many eyewear manufacturers have begun to duplicate adult eyewear designs into children’s glasses. That means you may even be able to find a mini-version of your own pair of glasses for your little one.

3) Lens material

After you’ve found the perfect frames, the next step is choosing lenses. When it comes to kids’s eyeglasses frames, polycarbonate lenses are highly recommended. They are extremely durable, scratch-resistant and offer excellent optics. Not to mention, they have built in protection against harmful UV radiation and can be made for any eye prescription.

It’s wise to stay away from glass lenses as these can easily break and cause serious eye damage.

4) Comfort is key

Firstly, protection and improved sight are the most important factors when choosing glasses for children. If you are going through the process of finding glasses that your child will take care of and love to wear, paying attention to comfort is key. You of course want your child to feel good and enjoy wearing their glasses, otherwise it will be very difficult to get them into this routine.

Take safety and UV-protection into consideration, but don’t forget to listen to your child’s opinions. After all – they will be the ones wearing the glasses every day and should feel comfortable and happy in their glasses.

5) Sports eyewear

If your child has an interest in contact sports, it may be a good time to invest in a pair of kids eyeglasses for sports.

Although regular polycarbonate lenses are durable enough, normal prescription glasses frames do not hold up so well when subjected to trauma. Sports goggles offer that little bit of extra protection and strength while providing the same great vision as normal prescription glasses. 

And there you have it! Hopefully these tips will come in handy when you’re choosing the perfect glasses for your children. At SmartBuyGlasses we offer several of the best-selling kids’ eyeglasses brands including Ray-BanCarrera, and more convenient models from SmartBuy Kids. Check out our full range here.

The Cause and Fix for Uncomfortable Glasses

Ask our dispensing opticians

Ask now

The Cause and Fix for Uncomfortable Glasses

Whether you wear glasses all day or just for a few hours at a time, it’s critical that you feel at ease. Unfortunately, uncomfortable glasses is quite a common problem. Typically, outgrown glasses are the issue, but sometimes new glasses are uncomfortable as well. 

If you’re always saying or thinking “my glasses are uncomfortable,” keep reading to learn the causes and solutions to ensure you are pain-free when wearing your prescription glasses

Why do my glasses hurt my nose?

You may suffer from a painful nose bridge if you wear glasses for lengthy periods of time. The main point of contact between your face and your glasses is the nasal bridge. As your nose supports and carries the weight of your spectacles, it can sometimes cause your glasses to feel uncomfortable on the nose. As well as a correct fit, looking for prescription glasses with adjustable nose pads can be a good option to reduce this discomfort. 

How to adjust nose pads on glasses

If your current glasses have nose pads that you feel cause more harm than good, you can get the nose pads adjusted to fit the shape of your nose. Choosing the right material for nose pads can also help you feel more comfortable when wearing your glasses. Materials such as silicon and finding the correct position will be the key to how to keep glasses from slipping off your face. 

Why are my glasses uncomfortable behind my ears?

Along with our noses, our ears are another common area of contact with glasses. Ache behind the ears is most often caused by frames that are excessively tight. If your glasses are too small, they will press on your skin and damage and disrupt your circulation. This can cause sore skin, redness, and even headaches. The correct fit or a quick adjustment can easily solve this issue.

How should glasses fit?

Good-fitting glasses should sit snugly on the bridge of your nose without pinching or feeling too tight on your head. Even when you’re moving around, the frames shouldn’t press into your face. It’s possible that the sizing is incorrect if your glasses pinch or move about. 

When buying prescription glasses or sunglasses, it is critical to get the glasses sizing correct. Use our size guide to ensure a proper fit and reduce the risk of soreness on the bridge of your nose or behind your ears.

Sometimes all that is required to alleviate discomfort is a simple adjustment. When it comes to adjusting glasses, SmartBuyGlasses understands that you might not have the time to take the frames to a professional. Fortunately, with the appropriate guidelines, you can adjust your glasses like an expert from the comfort of your own home. 

The last factor to consider is the material of your frames. Heavy frames, in addition to a poor fit, might cause discomfort. As a solution, you can experiment with glasses made from lightweight materials such as carbon fibre or titanium glasses

Now with the correct knowledge of how to avoid uncomfortable glasses, you can shop with ease online at SmartBuyGlasses and know you’ll be comfortable no matter what.

What Do You Need in Order to Buy Kids’ Glasses

When buying kids eyewear it is especially important that you choose the best possible design and quality in order to assure optimal eye health and comfort to your child. However, buying glasses online can always feel a little like a lottery, you haven’t tried them on so you aren’t sure if they will fit or suit your face shape, and without holding them in your hands you can’t get a feel for their weight or robustness. For this reason, we have put together a series of tips that you will need to take into consideration when buying your kids glasses online, to ensure that you get the best glasses for your child.

Before buying kids glasses you should keep the following info in mind:

How should glasses fit on a child? 

A child’s glasses frame should fit right into the eye socket from top to button and shouldn’t expand down the kid’s cheek. If a child is wearing a frame like this, it will cause unnecessary weight on the nose.

However, it’s no secret that children are growing. In relation to buying kids glasses and fitting glasses, this means that there may be a problem with kids glasses frames sliding down their noses. This can cause exasperation and discomfort for your child. The solution to this is to either buy kids glasses with metal frames and adjustable nose pads, or plastic kids glasses frames with specifically molded bridge parts.

Plastic has always been the traditional option as it is viewed as more durable and less expensive. However, modern metal children glasses frames now offer similar levels of resistance for comparable prices, as well as the extra feature of offering cable temples (which essentially hook over the back of your child’s ear), which are sturdier and reduce the chances of kids glasses sliding or falling off.

The PD or Pupillary Distance

The PD is the distance between the centre of each pupil. It’s crucial when fitting glasses correctly as it affects the way your child’s glasses lenses are positioned in their frames, and so will impact the accuracy of your child’s vision correction. In some extreme cases, not having the correct PD measurement can result in dizziness, headaches, and blurred vision.

All opticians measure this distance so it will most likely be noted on your child’s prescription. If it is not however, then you can either, revisit the optician and ask him to take the measurement for you, or read our article on how to measure the pupillary distance.

Lens thickness & materials

The thickness of the lens is dictated by the strength of your child’s prescription glasses. The higher the prescription (ie. the more vision correction needed), then the thicker the lenses will be. Your optician is best placed to advise you on the optimum lens thickness for your child’s prescription glasses. Be aware that due to recent advances in technology, many lens makers can now “slim down” lenses that once needed to be very thick.

The material of the lens should also be carefully considered. Traditional glass lenses have now given way in the most part to high quality plastic and polycarbonate lenses. Whilst you can still buy glass lenses, they are not advisable for children’s glasses due to obvious safety reasons, as well as being a much heavier material. For children, Trivex and polycarbonate lenses are usually recommended as they are lighter than plastic or glass lenses, and much more durable and impact-resistant. This allows for longer lasting comfort. So when buying kids glasses online always make sure you know the material of the lens you are purchasing.

Warranties

Many online optical retailers have warranty plans in place that cover damaged or broken eyewear at little to no cost. If your child is very young, or a first time glasses wearer, it’s recommended that you look into the warranty plans of each provider before you decide to buy. Check that it includes all the services you are looking for, e.g. lens replacement or free scratch repair. It could save you a lot of money in the future.

Spring hinges

A lifesaver for those whose children are slightly more “rough and tumble”. Spring hinges are glasses whose temples are fitted with springs at the hinges in order to provide more flexibility when the temple is moved back and forth. They increase resistance and durability and minimise expensive temple repair costs. They ensure flexibility in the arms of the glasses and don’t snap and break as easily as regular hinges.

Back up pairs

There is always the possibility that the worst happens and your child’s glasses break beyond repair (even beyond a “scotch tape and string” job). Therefore it’s highly recommended to have a pair of back-up kids glasses that are stored away and used only when necessary. Many optical companies offer great value with their in house brands, which means that an extra pair of glasses doesn’t have to be an expensive option. SmartBuyGlasses has a wide range of low priced, quality frames in their SmartBuy collection.

Silicone Hydrogel Lenses

Silicone Hydrogel Lenses

The development of contact lenses

Arguably the main preoccupation of contact lens developers over the years has been increasing oxygen permeability. If worn for an extended period of time, traditional contact lenses deprive the cornea of much-needed oxygen. Without adequate oxygen, the cornea dries out and can become inflamed, which is a condition known as keratitis. This can cause itchiness and pain, and in more severe cases, can impair vision and lead to long-term damage such as scarring. In the quest to find a longer lasting, comfortable contact lens, the ability to improve oxygen permeability is crucial. Thus, silicone hydrogel contact lenses have been a game-changer for all contact lens wearers. 

Silicone Hydrogel

Soft contact lenses were first created in the 1960s, after the development of ‘hydrophilic gels’ or hydrogels. Problems of keratitis became more widespread with the introduction of extended wear contact lenses in the 90s because more people were wearing contact lenses for longer periods of time. This resulted in many people getting infections.

The first silicone hydrogel contact lenses were introduced to the public in 1999. This amazing new technology allowed up to seven times more oxygen to reach the cornea compared to traditional hydrogel lenses, meaning that for the first time extended wear contact lenses did not lead to an increased health risk.

Oxygen permeability

The higher permeability of silicone means that the oxygen permeability of silicone hydrogel lenses is not tied to the amount of water in the lens. For the wearer, this means increased comfort, and the ability to wear the lenses continuously for an extended period of time. Studies have also shown that any infections that do occur tend to be less severe than with traditional Hydrogel lenses.

Contact lenses for dry eyes

Whilst they are not perfect, there is no denying that Silicon Hydrogel represents a major step forward in contact lens technology, and it is no coincidence that the market has been heading in this direction for some years now. Whilst they may not be for everyone, almost any contact lens wearer is in a position to try them out, though we will always recommend that you consult your optician before switching your contact lenses. People who stand to benefit the most from Silicone Hydrogel contact lenses are those who tend to wear their lenses for more than twelve hours a day, particularly if they spend a lot of time in low humidity environments (offices with air-conditioning is one example of this). Patients with high prescriptions, or younger people who haven’t yet got the hang of their contact lens wear and maintenance routine, will also benefit, as will anyone who regularly experiences dryness, redness, or any other discomfort towards the end of a day wearing traditional contact lenses.

Silicone Hydrogel Contact lenses come in a variety of brands and different duration of wear. Many Silicone Hydrogel lenses have been approved for overnight wear for up to seven nights, and there are even pairs that can be worn for up to 30 nights continuously.

How to choose the right contact lenses

What are the differences between daily and monthly contact lenses? Choosing the right contact lenses for your needs comes down to two main things, your prescription and lifestyle.

Daily contact lenses are typically thinner than monthly contact lenses and have high water content. 1 day silicone hydrogel contact lenses should for example be word for around 12 hours a day and then removed overnight to let the eyes rehydrate. Residue from the eye easily build up and affects the quality of the lens. Therefore, daily contacts should be disposed of and not reused after wearing them. If you play sports or engage in outdoor activities, daily contact lenses may be the better option for you as the lenses are likely to be exposed to dirt and can be replaced daily.

Monthly lenses are thicker and durable, making them more long-lasting. They do not dry out as easily if properly taken care of and stored and can therefore be reused multiple times. Your vision correction needs is important when choosing contact prescription lenses. Since monthly contact lenses are made with a harder composition, they are more suitable for prescriptions that require higher magnification. If you have a complex prescription, monthly lenses are typically more suitable for you.

If you have sensitive or dry eyes, silicone hydrogel contact lenses are a good option and together with your eye doctor you can discuss the perfect fit for your needs.

Silicone Hydrogel Lenses

The development of contact lenses

Arguably the main preoccupation of contact lens developers over the years has been increasing oxygen permeability. If worn for an extended period of time, traditional contact lenses deprive the cornea of much-needed oxygen. Without adequate oxygen, the cornea dries out and can become inflamed, which is a condition known as keratitis. This can cause itchiness and pain, and in more severe cases, can impair vision and lead to long-term damage such as scarring. In the quest to find a longer lasting, comfortable contact lens, the ability to improve oxygen permeability is crucial. Thus, silicone hydrogel contact lenses have been a game-changer for all contact lens wearers. 

Silicone Hydrogel

Soft contact lenses were first created in the 1960s, after the development of ‘hydrophilic gels’ or hydrogels. Problems of keratitis became more widespread with the introduction of extended wear contact lenses in the 90s because more people were wearing contact lenses for longer periods of time. This resulted in many people getting infections.

The first silicone hydrogel contact lenses were introduced to the public in 1999. This amazing new technology allowed up to seven times more oxygen to reach the cornea compared to traditional hydrogel lenses, meaning that for the first time extended wear contact lenses did not lead to an increased health risk.

Oxygen permeability

The higher permeability of silicone means that the oxygen permeability of silicone hydrogel lenses is not tied to the amount of water in the lens. For the wearer, this means increased comfort, and the ability to wear the lenses continuously for an extended period of time. Studies have also shown that any infections that do occur tend to be less severe than with traditional Hydrogel lenses.

Contact lenses for dry eyes

Whilst they are not perfect, there is no denying that Silicon Hydrogel represents a major step forward in contact lens technology, and it is no coincidence that the market has been heading in this direction for some years now. Whilst they may not be for everyone, almost any contact lens wearer is in a position to try them out, though we will always recommend that you consult your optician before switching your contact lenses. People who stand to benefit the most from Silicone Hydrogel contact lenses are those who tend to wear their lenses for more than twelve hours a day, particularly if they spend a lot of time in low humidity environments (offices with air-conditioning is one example of this). Patients with high prescriptions, or younger people who haven’t yet got the hang of their contact lens wear and maintenance routine, will also benefit, as will anyone who regularly experiences dryness, redness, or any other discomfort towards the end of a day wearing traditional contact lenses.

Silicone Hydrogel Contact lenses come in a variety of brands and different duration of wear. Many Silicone Hydrogel lenses have been approved for overnight wear for up to seven nights, and there are even pairs that can be worn for up to 30 nights continuously.

When buying a new pair of sunglasses and choosing the colour of your lenses, remember that different lens colours have different purposes.

Depending on weather conditions or the activities that are part of your daily routine, the colour of your lenses can enhance the overall performance of your glasses. Most people choose lens colours based on aesthetics, but did you know that different lens colours serve different purposes? 

In this article, we will guide you through the different colour options, explain the difference between each lens colour and help you understand how to choose the best one to suit your needs.

Does the colour of sunglass lens matter?

Yes, colour has a noticeable effect on the sunglasses. Depending on your lifestyle, lens colour also affects your eye health during certain activities. This makes it essential for you to find a suitable lens compatible with your daily activities and needs.

What about mirrored lenses?

Mirrored sunglasses are the perfect stylish option to protect your eyes against UV rays. The fully reflective coating used for the lenses gives the mirrored look everyone loves these days. Combined with polarised lenses, they offer maximum protection against UV rays and increase clarity. Both polarised and mirrored lenses, either separate or combined, come in different colours. Below, we will be listing the most popular colours and what is the advantage of choosing each lens colour.

Lens colour guide

Grey and black lenses are the best option if you’re looking for a neutral lens tint. These lenses are perfect for all weather conditions and are the top choice if you want to perceive colours in their purest form, even when wearing sunglasses.

Grey lenses are great at reducing the brightest glare and are perfect for outdoor activities and sports such as surfing, cycling, golfing and driving. If you’re looking for the everyday use type of tint, this is the one.

Amber and brown tints are extremely popular as they provide excellent depth perception. These lenses have a warm, reddish tone and are perfect for reducing glare, enhancing contrast, and helping maintain visual acuity. Amber and brown lens sunglasses are perfect for sunny days and outdoor activities such as fishing, shooting, tennis, or baseball.

Green Lenses are one of the trendiest when it comes to polarized or mirrored sunglasses. They are perfect for sunny days but also in low light conditions. Whether sunny, cloudy, or anything in between, green lenses will work amazingly well, giving you excellent vision and reducing glare.

Green lens sunglasses are one of the most popular ones for outdoor activities: no matter what sport you have on your agenda, these lenses will increase contrast and visual sharpness and enhance shadow.

Yellow lenses are more efficient in low-light environments like cloudy or rainy days. One of the benefits of using yellow lenses is that when playing sports, these lenses are great for focusing on moving objects. Another advantage is that when navigating, they are perfect in hazy or low-light conditions. Yellow lenses are also very popular amongst gamers as they filter blue light from computer screens and other screen devices.

Blue lenses are not only very trendy but also well-known for enhancing clarity and defining contours. These lenses improve colour perception and do wonders in low-light conditions. They’re suited well for all water sports, snow sports, and golf. 

Red and pink tints increase contrast by blocking blue light and enhancing depth perception. They are also soothing for the eyes and more comfortable than others for longer wear times. Pink and red lenses perform their best on extremely sunny days and snowy conditions.

DID YOU KNOW?

Black lenses are perfect if you’re looking for a neutral lens tint while brown lenses provide excellent depth perception. Blue lenses are suited for all water sports. For rainy days, yellow lenses are a must!
