Home Care
The discomfort of light sensitivity can be reduced by avoiding sunlight, closing the eyes, wearing dark glasses, or darkening the room. However, the cause for the light sensitivity should be determined since proper treatment may cure the problem.

Call your health care provider if

• Light sensitivity is severe - i.e., if you need to wear sunglasses indoors.
  
• Accompanied by headaches, red eye(s) or blurred vision.
  
• Sensitivity to light that does not go away in a day or two.
