Glare is the feeling of discomfort and failure to see how well we experience when a light source affects us directly or indirectly in our eyes.
It causes visual discomfort, eye fatigue and increases the risk of accidents. The usual solution is to wear sunglasses.
There are certain pathologies that increase glare. They are all those that affect the transparency of the cornea, crystalline or edema in the retina. In these cases, sun lenses or special filters are used.
