What is light sensitivity?

There are times when the amount or quality of light can affect our ability to see. Many people with low vision need more light than usual to read. However, too much light can cause problems with glare.

Discomfort glare occurs when a light source is just too strong for our eyes. It may cause us to screw up or shade our eyes; it can even cause us to close our eyes.

Disability glare reduces how well we can see. Disability glare can be caused by eye conditions and can occur with ordinary light sources and levels of light.

A low vision specialist can give you advice on coping with glare. They can talk to you about the best way to use lighting to avoid glare.

More information can be found on our light sensitivity (photophobia) web page.

We also have a light sensitivity (photophobia) factsheet:
