What Are the Causes of Eyeglass Glare?

Glare is produced when light bends, or refracts, and the particles scatter along the surface of an object. Eyeglass glare can be frustrating, but it can be minimized through proper eye care and protective lenses.

Causes
•Glare can be caused by the sun’s reflection on car windshields or pavement, or by bright headlights. Indoor lights, such as computer screens, can also cause glare.

Considerations
•Middle-aged and older people are more sensitive to glare from eyeglasses. It takes their eyes longer to adapt to changing light.

Prevention/Solution
•Glasses with anti-reflective (AR) coating reduce glare and internal reflection in the lenses, while allowing adequate light to pass through.

Tips
•The American Automobile Association (AAA) notes that headlights pointed even one degree too high can result in greater glare. They recommend checking your headlights, as well as your mirrors, for proper alignment.

Warning
•Spending more than two hours daily at a computer screen can cause significant eyestrain. Computer glasses geared specifically for this purpose can minimize glare and bring relief, according to the Macular Degeneration Support website.
