Sure, sunglasses might add the final touches to your chic ensemble, but the real reason to purchase your shades is to protect your eyes from the sun. Not only does glare from the sun make it difficult to see, but the UV rays it reflects can cause permanent damage to your eyes and vision. You want to make sure your sunglasses offer optimal protection, fit, comfort and of course, the best possible vision. Here are some things to consider when purchasing your next pair. 

UV Protection

There are two types of UV radiation, UVA and UVB. UVA rays are less intense yet more prevalent than UVB rays, making up 95% of the UV radiation that reaches the surface of the Earth. They have been linked to skin cancer, aging and the development of cataracts. UVB rays are very dangerous to the eyes and are the primary cause of sunburns and cancer. While they are dangerous year round, these rays are more intense during the summer months, especially mid-day between around ten in the morning and four in the afternoon. UVB rays also reflect off of snow, water, sand and concrete. 

The damage caused by UV rays is irreversible and cumulative, building up over a long period of time. This is why it is important to start wearing sunglasses when you are young (also because your eyes are more sensitive at a younger age). You want to make sure your sunglasses block out 100% of UV rays. This is the most important factor to consider when purchasing your sunglasses. 

Additionally, in certain circumstances of intense UV exposure, a condition called keratitis can occur, which is essentially a sunburn on the eye. Symptoms often occur hours after sun exposure and can include temporary vision loss and severe pain. 

Sunglass Lens Options

Once you are certain your sunglass lenses have the requisite UV protection, you can begin to consider other lens possibilities. Here are some other lens options to consider:

Polarized Lenses:

Reduce glare from light reflecting off glass, water, snow, sand or pavement. You should consider polarized lenses if you participate in water or snow sports such as fishing, boating or skiing as the water and snow can create a strong glare. They are also great for comfort while driving by reducing glare and to enhance vision when on the road. 

Tinted Lenses:

Certain lens tints enable you to see better or more comfortably under certain circumstances but you have to be careful. Lens tints can distort or reduce vision and some can even harm your vision by increasing your pupil size which leads to an increase of UV radiation penetrating the eye. Look for lenses with a medium tint that keep your eyes comfortable and do not have a negative impact on your vision. Your optometrists? office can often make specific tint recommendations depending on your lifestyle or particularly activities (ex. golfing vs fishing) and the health of your eyes (for example, cataracts tend to cause more glare). 

Photochromic Lenses:

Automatically darken when exposed to UV light. Photochromic lenses are a great option for individuals that wear prescription eyeglasses: one pair can serve you both indoors and outdoors. As soon as you step outside, the lenses will darken, and they?ll reverse when you go back indoors. 

Lens Materials

There are also a few options when it comes to lens materials, such as plastics – including polycarbonate or acetate; trivex – which is a polymer material; or glass. The type of lens will determine the durability, clarity of vision and price of your lenses, so you should consider the factors that are most important for you and try out a few options to see how they feel. 

Sunwear Frames

Frame Size

The size of your sunglass frame is important for both comfort and protection. Your frames should fit according to your face size and provide ample coverage for your eyes. When you try on your frames, make sure they cover your eyes and feel comfortable around the bridge and temples. Also check that they don?t slip off when you move your head down toward the floor. 

Frame Materials

Frames can be manufactured from a number of materials and, these days, frame companies are constantly innovating to come up with new and improved options. These materials vary in strength, flexibility, weight, comfort and price. You need to choose a frame material that is comfortable, safe, and functional and that suits your lifestyle and your fashion style. 

Making the Purchase

When purchasing sunglasses, keep in mind that your vision insurance may help to cover the costs when purchased at an optometry office rather than at a sports or recreation store. Check with your insurance and your local optical to find out about any discounts or coverage. Another advantage of purchasing from an optometrist?s optical is that the optician can help you to find the perfect pair to suit your eye and vision needs, as well as your lifestyle and fashion preferences. 

The good news about choosing the right pair of sunglasses is that there are ample brands, colors, styles and materials to choose from. So when it comes to your shades, don?t settle for less than optimal protection, fit and comfort for your eyes.

  • What is Neuro-Optometry?

    Neuro-Optometry focuses on the intricate connection between your visual system and the brain, extending beyond traditional eye care to assess functional vision. This branch of optometry examines how your eyes track, move, coordinate, and how your brain processes depth, motion, and balance. Disruptions in these functions can lead to a range of issues including headaches, migraines, dizziness, balance challenges, post-concussion symptoms, reading difficulties, and attention deficits (ADHD). By exploring these functional areas, we also identify opportunities to enhance performance in activities such as sports, reading speed, and cognitive processes.

  • What is Vision Therapy?

    At Opto-Mization, vision therapy is a specialized, personalized program aimed at improving visual skills and abilities. It goes beyond traditional vision therapy to help improve how the eyes and brain work together, addressing visual-motor and perceptual-cognitive challenges to enhance overall visual function. It’s more than just exercises; it’s a pathway to better vision and improved daily life.

  • Do you Provide Regular Eye Exams and General Optometric Services?

    Yes, alongside vision therapy and neuro-optometry, we offer comprehensive eye exams and general optometry services. Our experienced optometrists perform thorough eye exams to evaluate overall eye health, identify any eye conditions or diseases, and prescribe corrective lenses when beneficial.

  • Who is the Ideal Candidate for Vision Therapy and Neuro-Optometry?

    Vision therapy and neuro-optometric rehabilitation can help individuals of all ages. Whether you’re struggling with visual processing issues, binocular vision disorders, amblyopia (lazy eye), strabismus (eye misalignment), or have sustained a brain injury, our services might be beneficial for you. Contact us to discuss if our tailored approach can meet your specific needs and goals.

  • Do I Need a Referral to See an Optometrist at Opto-Mization?

Feel free to reach out and schedule your appointment directly with us to take the first step toward understanding and improving your visual function.
