A pair of sunglasses is a need for the summer! You probably have been wearing them ever since you were a kid and your parents would always remind you to put them on before going outside to play. Then, they were fashionable when I was an adolescent. You might also be interested in the benefits of sunglasses as an adult.

There are various benefits to wearing sunglasses every day of the year, whether sunny or not. Protecting your eyes from damaging UV radiation from the sun should be a top priority because it is present in our atmosphere every day.

How do sunglasses work?

Sunglasses often have UV-protected lenses built into them. Some might have UV-protective lens coatings.

UV protection blocks or reflects the two common types of sunlight, UVA and UVB.

How do you determine whether your sunglasses offer UV protection, then? Look for sunglasses with a label stating they offer 100% protection from UVA and UVB radiation.

Features of good sunglasses

Sunglasses come in a variety of sizes, forms, and designs. They can also have tinted, mirrored, or polarized lenses. The following qualities should be present in sunglasses:

• For ultraviolet protection, they should have 90 to 100% UVA and UVB blockage.
• They should have the proper frame, lens, and lens color.
• Frame and lens materials and quality
• lens layer that is anti-scratch and anti-reflective

Types of sunglasses 

1. Sport sunglasses:  Sunglasses for fast-paced sports like riding, jogging, or hiking are known as sports sunglasses. They provide complete eye coverage, lightweight, durable construction, adjustable lenses, and unobscured vision. Additionally, they contain gripping nose pads and temple ends to help you keep them on even when you sweat while working out. A pair with premium frame and lens materials is the best choice since they are more flexible, robust, and able to resist high-impact activities.
2. Glacier glasses:  Glacier glasses are specialized sunglasses that shield your eyes from bright light in front of you, glare off the snow, and powerful light at high elevations. Additionally, they have an extension feature that wraps around to shield your eyes from sidelight.
3. Casual sunglasses: Casual sunglasses are ideal for an active lifestyle and simple recreational use. They shield your eyes from the light as you go about your tasks.

Can your eyes be harmed by wearing sunglasses? 

Sunglasses that are worn incorrectly or don't block UV might harm your eyes.

When the light is faint, or you wear dark shades, your pupils dilate as your eyes adjust to the ambient light. It expands the area where UV can reach the eye. You risk eye injury if the lenses are only colored and do not block UV. 

Importance of sunglasses

Sunglasses are a useful accessory for eye protection and overall visual health because they provide several advantages for the eyes. Here are some explanations as to why wearing sunglasses protects your eyes:

• UV protection: High-quality sunglasses shield the eyes from the sun's damaging ultraviolet (UV) rays. Long-term UV radiation exposure can cause several eye issues, such as photokeratitis (corneal sunburn), macular degeneration, and cataracts. UV-protective sunglasses can help protect the eyes from these harmful rays.
• Glare reduction: Polarised sunglasses lenses can lessen glare from reflections from flat surfaces like snow, water, and roadways. As a result, it is simpler to see clearly and comfortably in bright situations, and there is less eye irritation.
• Comfort and relaxation: Sunglasses can greatly improve eye comfort and relaxation when worn outside on sunny days. The lenses aid in lowering the brightness of bright light, improving outdoor comfort and lowering squinting, which can cause tension headaches.
• Protection from wind and debris: When participating in outdoor activities, sunglasses are a physical barrier that shields the eyes from wind, debris, and dust. It lessens the chance that foreign things will irritate, aggravate, or even harm the eyes.
• Preventing dry eyes: Sunglasses can help by shielding the eyes from direct airflow and reducing the evaporation of tears. It helps maintain normal eye moisture and lowers the likelihood of experiencing symptoms of dry eyes, which is especially helpful in dry and windy situations.
• Eye health and aging: Long-term exposure to UV rays without adequate protection can hasten eye aging and raise the risk of disorders related to the eyes. As you mature, wearing sunglasses from a young age can help preserve healthier eyes.

It is essential to get high-quality sunglasses that offer 100% UV protection and fit comfortably on your face to give your eyes the most benefit and protection possible. To monitor and maintain your eye health, it's also essential to get yearly eye exams with an ophthalmologist or optometrist.

When to wear sunglasses and what to look for in a pair

Baseball caps and hats with a wide brim only block about half of the sun's ultraviolet rays. And although you can buy some with a specific UV-blocking substance, polarised lenses don't stop them from coming in.

Sunglasses that completely or almost completely block UVA and UVB rays can provide appropriate protection for your eyes. Additionally, bear the following in mind when selecting sunglasses:

• Reduce visible light by 75% to 90%
• The same degree of blackness in the lenses. If the lenses vary from light to dark, the top should be the darkest, and the transition should be gradual.
• Lenses that don't unnaturally alter your field of vision, grey lenses, enable accurate colour vision
• A frame that complements the contour of your face and is close to your eyes

Suppose you engage in outdoor activities or employment that could endanger your eyes. In that case, you should wear eyewear with impact-resistant polycarbonate lenses or a substance known as Trivex. To shield your face from wind and UV rays coming from the side, you should also acquire sunglasses that wrap around your face.

Children and teenagers should also wear proper sunglasses. Up to 80% of a child's lifetime sun exposure might occur before age 20.

Avoid the sun between the hours of 8 and 10 in the morning and 2 and 4 in the afternoon. Those are the prime times when UV rays can harm your eyes.
