1. Disease prevention
Many people aren’t aware that the sun can harm your eyes and the skin around the eyes. UV rays can increase the risk of cataracts - up to 20% of cataracts may be caused by overexposure to UV rays, according to the World Health Organisation.
Other eye conditions that can result from too much UV exposure include photokeratitis, macular degeneration, melanoma, and pterygium.
Sunglasses protect against sun damage to the eyes and they also provide protection against harsh wind, dust, sand, and other airborne debris that irritate the eyes or could scratch your cornea.
Driving with polarised sunglasses can increase your reaction time than when not wearing sunglasses. Sunnies reduce glare and keep you safe when driving or riding a bike.
3. Less strain, fewer headaches
You may know about blue light that comes from computers and other digital devices and that the light can cause eye strain, headaches and burning eyes.
But did you know that blue light can also come from the sun!
4. Improved dark adaptation
Sunglasses increase visual clarity by blocking UV rays and reducing glare during the day. They can also have a positive impact on your sight at night.
The American Optometric Association found that daytime exposure to ordinary sunlight can produce temporary but cumulative after effects on dark adaptation and night vision. High-quality polarised sunglasses can help reduce night vision loss.
5. A better outdoor experience
Non-sunglasses users can often rely on compensatory behaviours when outdoors. Many squint or avoid the sun as much as possible. Prescription sunglasses provide you with comfort, clarity, protection, and freedom to enjoy the outdoors.
