Specialty Eyewear Overview

You may think that you are set with your everyday eyewear, but there are a lot more options than just sun and ophthalmic glasses. Whether it’s water sports, a construction job or even working around the home, there are many circumstances which require specialty eyewear to add extra protection, prevent injury, and improve vision and performance. Here is an overview of some of the different types of specialty eyewear to consider.

Sports Eyewear

Typical eyewear is not made to hold up to the safety and performance standards required for sports and athletic use. Sports eyewear is made of stronger materials and design for ultimate impact resistance and durability. Sports eyewear is also designed for ultimate comfort, fit and coverage to protect from elements such as sun, water or wind. The lenses are also made with impact resistant materials such as innovative plastics such as Trivex or Polycarbonate. Most lenses will also include 100% UV protection, anti-glare and anti-scratch properties to further protect the lenses. Polarized lenses will also aid your sports eyewear to improve vision in outdoor environments. Depending on your sport there may be a specific type of eyewear suited to your needs such as sports goggles, shooting glasses or ski goggles. Speak to your optician about your sport of choice to determine the safest and most effective eyewear for you.

Computer Glasses

If you sit for extended periods of time at a computer or in front of a handheld screen you are at risk for computer vision syndrome, eye strain, eye fatigue, headaches and muscle strain. This is largely because your eyes view a computer screen differently than they view the world around you. Glare from the screen can also exacerbate these issues. Computer glasses are designed to reduce the strain and to create a more comfortable visual experience when looking at your screen.

Reading Glasses

As we approach the age of 40, our near vision begins to weaken – a condition called presbyopia. This can be corrected by wearing reading glasses when reading or doing close work. There are a number of options for reading glasses depending on your vision needs. People with distance vision correction needs may prefer bifocal or multifocal lenses that allow you to see at a distance as well with the same pair of glasses. It is worthwhile to speak to your optometrist to find the best solution for your vision near and far.

Safety Glasses and Goggles

Whether you are working with power tools in construction, mowing your lawn or using harsh cleaning products, there are plenty of household projects and hobbies that can pose a serious risk to your eyes and vision. Whether it is the danger of debris being projected toward your eyes or a chemical splash, safety goggles or glasses should be worn whenever dealing with dangerous materials or machinery.

Specialty eyewear manufacturers are always developing new innovations to protect your eyes and improve your vision during the activities that you enjoy. Ask your optometrist about the specialty eyewear that is suitable for your interests and hobbies.

Lens Options for Eyeglasses

If you thought the trickiest part of choosing a new pair of glasses was the frame selection, think again. You should be putting just as much thought and consideration into the lenses that you select for your new specs.

Here’s why: The quality and type of lenses in your eyeglasses will not only correct your visual acuity, but they will allow you to continue to see your best through various conditions. Whether it is keeping the lenses free from scratches, fog, glare or UV rays, or making them stronger or more attractive, your eyeglass lenses can help to keep your eyes safe and comfortable wherever the day (or night) takes you.

Lens Coatings

Here are a variety of coatings that you can apply to your lenses to maintain optimal vision and comfort and to protect your lenses and your eyes.

Anti-reflective/Anti-glare Coatings

Anti-reflective (AR) also known as anti-glare coatings help reduce the reflections and glare on your lenses, improving your vision and comfort in high-glare environments, and the look of your glasses as well (you can see your eyes clearly without a reflection on the front of the lens). Reflections from the sun, television and computer screens and bright lights (especially when driving at night) can cause eye strain, headaches and difficulty seeing. AR coatings and lenses can reduce this effect, improving your vision quality and comfort in these circumstances.

Scratch Resistant Coatings

Scratches not only affect the smooth look of the surface of your glasses but they can disrupt your vision. A scratch-resistant coating adds an extra layer of protection on the surface of the lens to significantly reduce scratching. This coating is particularly great for kids who may tend to be a little more rough with their eyewear.

Ultraviolet Coatings

Ultraviolet (UV) coatings protect your eyes from harmful UV rays from the sun. This coating can turn standard lenses into UV blocking lenses that can block 100% of the UV light from entering your eyes. UV is linked to the development of a number of eye diseases such as cataracts, macular degeneration and retinal damage.

Anti-fog Coatings

Particularly if you live in a cold climate, you may have experienced walking indoors from the cold and having your glasses lenses fog up completely. This can take a few minutes to resolve and can be dangerous if you are driving or need to see clearly. Anti-fog coatings will eliminate this effect, creating a smooth transition from cold to hot environments.

Lens Options

You may want to go with an upgraded lens to improve the look, strength or functionality of your glasses.

High Index Lenses

High index lenses have a higher refractive index which means they reflect more light than standard prescription lenses. What this means for you, the consumer, is that they can be made thinner and lighter than traditional lenses. High index lenses are particularly popular with those that need a high prescription as they are able to avoid thick lenses, adding comfort and a smoother look, but a higher price tag.

Trivex or Polycarbonate Lenses

Trivex or polycarbonate lenses are impact resistant lenses – a fantastic choice for sports and safety eyewear as well as standard sunglasses and eyeglasses for active types or kids. These lenses also offer full UV protection and are lightweight for optimal comfort.

Polychromatic Lenses

Polychromatic lenses are made with special technology that turns them into sunglasses when exposed to sunlight. The lenses darken automatically when you go outside and return to normal when you go back indoors. Polychromatic lenses can come in a number of tint colors and are great when you need prescription sunglasses but don’t want to carry around or pay for another pair.

Aspheric Lenses

Aspheric lenses use advanced technology to create a slimmer, flatter and lighter lens than standard prescription lenses. While aspheric lenses can improve the appearance of any prescription lens, they are especially beneficial for those who are farsighted since those lenses tend to bulge out in the middle.

So the next time you are in the market for new eyeglasses, speak to your optometrist or optician about the best lens choices for your eyes, your vision and your lifestyle.
