When the eye reacts to bright light, your pupils constrict, and in the dark, they dilate.When you wear sunglasses with dark lenses, the pupil will dilate in response to the dark filter in front of it, permitting more light into the eye. This is the reason why it is important that sunglasses have filter qualities in addition to a dark colour. Sun rays contain ultra violet. UV is not a light, it is a radiation.It is precisely for this reason that you should only ever wear sunglasses with 100% UV protective lenses. At Smith & Walker Optometrists all our Sunglass products ( including Photochromatic lenses ) offer 100% UVA/UVB protection.
