Buying Sunglasses to protect your eyes.
The importance of protecting your eyes from the sun cannot be overstated.
UV radiation from the sun can cause damage to nearly every layer of the eye right through to the retina at the back of the eye.
It can cause pinguicula's and pterygiums on the scleara (white of the eye) that can grow across the pupil, cataracts on the intraocular lens and macular degeneration at the retina.
It is very important to wear sunglasses with 100% UV block to protect your eyes and not just in the summer months.
Wraparound styles are better as they limit the amount of stray light the reaches your eyes from the edges of your sunglasses lens.
The UV index is a good guide as to the level of UV and the potential danger to your eyes on any given day.

UV light causes damage as it is high energy light. the closest colour from the visual spectrum to the UV spectrum is blue light and is also high energy wavelengths.
This is why blue light glasses are essential for blocking harmful blue light from computer screens.
