Light Sensitivity (Overview)

Light sensitivity or photophobia means when the bright light or sun bothers your eye. This can be from very dry eye with cornea surface issue, corneal scratch or ulcer, and eye inflammation from iritis. This happens due to iris spasm. Iris is like an aperture of camera open and close based on the light intensity.

See your primary doctor for evaluation, tests and imaging. ...Read more

Is there a cure for light sensitivity or am I just stuck with it?

Maybe: Your eyes can be sensitive to light for a number of reasons. If the sensitivity is due to a condition that is irritating the cornea or iris, than treating those conditions will help the sensitivity. If your eyes are healthy, but just generally light sensitive, then decreasing the sensitivity by blocking some of the light with sunglasses or hats may help. A complete eye exam is recommended. ...Read more

How often and for how long should I be taking Atropine drops for iritis? When should the discomfort and light sensitivity go away?

How often and for how long should I be taking Atropine drops for iritis? When should the discomfort and light sensitivity go away?

Depends: You probably are seeing an ophthalmologist (I hope not an optometrist) for this potentially serious medical condition. Atropine helps by relaxing the internal eye muscles and also helping to prevent internal adhesions (synechia) between the iris and the lens. Atropine helps as long as the inflammation continues which depends mostly on the response to steroids which I assume you are also taking. ...Read more
