Q&A with Dr. Gentile

I have trouble driving at night. What can I do to improve my night vision?

A. Prescription eye glasses may improve driving at night especially with anti-reflective coatings that can cut down on glare. If you have visually significant cataracts, cataract surgery is an option to improve night vision by replacing your cloudy natural lens with a clear implant. Learn more about prescription glasses
