If you're now on a vacation at Tibet, on autumn (or winter), you may not think that you need a pair of sunglasses, but when you're there, you'll find you're wrong, because you will be exposed to the sun rays for a long time in a day although it's on fall! And remember, Tibet has as long as 3,005 hours of sun lights in a year, much longer than other areas at the same latitude.

Why do you wear sunglasses? Nearly 90% of people believe that protecting their eyes is key to overall health. But most people who choose to wear sunglasses do so only to cut down on the sun’s glare.

There are many more reasons why you should wear sunglasses more often, especially when you’re enjoying the outdoors, no matter during summer or other seasons. 

 

1. PREVENT SUN-RELATED HEALTH PROBLEMS

Our eyes are sensitive. Prolonged exposure to sun can lead to a variety of ailments. Some are simply painful or irritating, others can be deadly serious. But remembering to wear a pair of high quality sunglasses can help to keep you safe from the sun’s damaging rays.

Let me start by defining what I mean by “high-quality” sunglasses. When choosing sunglasses, start by looking for sunglasses with 100% UVA and UVB protection. This provides full protection against the sun’s ultraviolet rays. Polarized sunglasses can reduce glare, which is nice if you’re spending a lot of time on the water. Also look for sunglasses that fully cover your eyes. Wrap-around lenses are even better because they block out light and glare from the side, as well as the front.

Now let’s look at diseases and health complications that sunglasses can help protect against.

SKIN CANCER

The skin around your eyes, including your eyelids is very sensitive to sunlight. And nearly 10% of skin cancers are found near the eyes. Wearing UV-protective wraparound sunglasses with large lenses can not only protect your eyes, but they’ll protect your skin, too.

CATARACTS & GLAUCOMA

Cataracts are cloudy areas on the eye’s lens. According to the Glaucoma Research Foundation, prolonged and long term exposure to the sun’s UV rays contribute to cataracts. UV exposure may also worsen the symptoms of Glaucoma, another serious eye condition that can result in blindness. Sunglasses with complete UV protection can help reduce your risk of cataracts or complications from glaucoma.

MACULAR DEGENERATION

Macular Degeneration is a condition where part of the retina, called the macula, deteriorates, causing impaired vision and in many cases, eventual blindness. Certain types of UV radiation can speed up this process, so wearing sunglasses may help protect you.

PTERYGIUM

Also known as surfer’s eye, pterygium is a growth on the eyeball itself. It’s usually not serious, but it can be painful and annoying. Eye drops, steroids and surgery (in advanced cases) are the most common treatments.

But the best treatment, of course, is prevention. Doctors recommend wraparound sunglasses with UV protection, especially on cloudy days when the sun isn’t visible but its UV rays can still damage the eyes.

 

2. PROTECTION FROM THE ELEMENTS

The sun isn’t the only thing that can damage your eyes. Spending time outdoors, puts you at additional risk of damage from sand, dust, wind and even snow.

SNOW

You might be surprised to know that spending time in the snow can be very damaging to your eyes. Snow reflects 80% of UV rays from the sun and can cause a condition known as snow blindness, where glare from the sun actually burns the cornea.

If you’re skiing, climbing snowy mountains or spending time in the snow (at any time of year), wear sunglasses. Make sure they cover and protect the bottom of your eyes, because of the reflective nature of the snow.

SAND

Getting sand in your eyes can be very painful and dangerous. Tiny grains of sand can actually scratch your eye and can cause permanent damage. Sunglasses that fully cover your eyes are a great way to keep sand out.

WIND & DUST

Spending a lot of time in windy, dusty areas can irritate and damage your eyes. Again, the best way to protect yourself is by wearing sunglasses that keep your eyes safe from the elements.

 

3. PROMOTE HEALING & RECOVERY

If you’ve had LASIK or PRK surgery to correct your vision, you should be extra sure to wear sunglasses. Your doctor may recommend a pair for you to wear immediately after the procedure, but continuing to wear sunglasses can protect your eyes as they heal and as you adjust to your new vision.

Corrective surgeries are commonplace, but with improper post-surgical care, there can be complications. Avoid them by following your doctor’s orders and wearing sunglasses to protect your newly restored vision.

If you’ve had cataract surgery, eyelid repair, or another procedure to correct your vision, you’ll also benefit from wearing protective sunglasses. Ask your doctor for his or her opinion and recommendations.

 

4. YOU’LL SEE MORE & ENJOY THE OUTDOORS MORE

As important as protecting your health is, there are more good reasons to wear sunglasses more often. If you’re spending time outdoors, you’ll really benefit from wearing your sunglasses.

If you enjoy fishing or spending time on the water, with the right sunglasses, you’ll be able to see through the glare on top of the water and notice fish and aquatic life that you never even knew was there!

 

5. FOR SAFER DRIVING & RECOVERY

Do sunglasses help when driving in the rain? This is a hotly debated issue, but the consensus seems to be that in light rain, during the day, the right sunglasses can improve your vision and help you to drive safer. And of course when driving into bright sunlight, sunglasses can definitely help you see better and drive more comfortably. Just make sure you don’t wear sunglasses when driving at night– that’s not recommended and it’s not safe.
