Serious Warning Signs of Cataracts

Sensitivity To Light And Glare

Sensitivity to light and glare is a common symptom of cataracts. This sensitivity may get increasingly worse as cataracts grow and distort the patient's vision. Light sensitivity might be caused by the unusual dispersion of light through the foggy lens. Instead of seeing the light's rays as they are, patients experience them as more intense and blurred images. It's common for individuals to become more light sensitive as they age. However, cataracts can cause this sensitivity to affect even normal light levels.

There are two types of glare defined by professionals: disability and discomfort. A discomfort glare is a too-strong light source that causes pain. Everyone with normal vision has experienced this at some point; one example is walking from a dimly lit room into bright sunlight. A disability glare occurs when an eye disease, like cataracts, causes an individual to become intolerant to average light sources.
