What are sunglasses?

The word sunglasses is commonly spoken about, and many would know what it means. By definition according to the dictionary, it is: eyeglasses with colored or tinted lenses that protect the eyes from the glare and dangerous rays of sunlight. The thing is, do we actually know how sunglasses protect the eyes? How it actually works?

The sun damages the eyes, and the effect is posted below (cataract). Check out a video of how sunglasses work and why each one of us should at least have 1 or more QUALITY sunglasses. Enjoy the video!

I remember clearly the words of my honourable Professor in Ophthalmology (eye specialist).

"Cataract is a leading cause of visual impairment in the elderly and can be EASILY prevented by wearing UV protective sunglasses! Elderly people didn't have the chance to wear sunglasses in the past, hence they succumb to cataract now. You youngsters should wear sunglasses as often as possible to prevent cataract!"

Those words remained in my mind till now, and I'm sure you'll benefit from this sharing!
