This app is used as a screening device to detect the presence of nighttime glare.

This application is useful to driver rehabilitation specialists who perform vision screening as part of their evaluations.

"I use the Night Glare app with patients who I am concerned about night vision and/or who have an eye disease."
- Kristin Nichols, Registered and Licensed Occupational Therapist and Certified Driver Rehabilitation Specialist

An important benefit of the app is that it can make it easier to discuss the hazards of driving at night with elderly family members and friends.

A survey from the National Safety Council and found that adult children ranked talking to elderly parents about their driving more difficult than talking to them about selling their house or even funeral wishes.

More than half of adult children of senior drivers say they are concerned about their parents' driving habits but only 23% have had a discussion with their parents about driving abilities, according to a survey conducted by Liberty Mutual Insurance.


. Use the app in a dark room with your best vision. *

. While seated, place your mobile device on the floor between your feet.

. Test with both eyes and then each eye individually.

. During the test, if you see glare from the blinking central light source that extends to the outer circle, we recommend that you draw a sketch of your glare pattern and consult with your eye care professional.

*For best results, please ensure your display is on the brightest setting

Please share this test with your family members and friends. Nearly one in three drivers reports having difficulty seeing at night when driving, according to a study conducted on behalf of Road & Travel Magazine and Acuvue contact lenses.

Night Glare

Amazing and easy to use tool to identify night time driving difficulties. The convenience of taking the test at home is great. I talked to my eye doctor about my slight glare identified with the Night Glare app. We now have a baseline to monitor the condition as the aging process continues. Thanks to the designer and programmers for creating an extremely helpful app.

Night glare proves me wrong

Took it lightly. Did not believe that my fantastic eyes suffer from glare. But what do you know. That simple to use application will send some people back to the ophthalmologist to correct what needs to be corrected if possible.

Amazing APP!

This APP helped me confirm I have a slight glare issue in one of my eyes after an injury. While it is not a significant issue right now, I am able to bring it up with my eye doctor so she can monitor the situation. Very easy to use and accurate results!
