Causes of Halos and Glare continued...

 

Eye procedures. Some procedures can result in halos and glare. These include radial keratotomy and laser procedures such as LASIK and PRK.  The more modern forms of LASIK are much less likely to produce glare and halos than the older procedures. 

Causes of glare that can interfere with vision include driving toward the sun at sunset or looking across a beach or snow-covered field on a sunny day.

Laser pointers entering your eye can also create harmful glare.

Camera flashes can cause glare that leaves temporary afterimages in your vision. This is also called flash blindness.

 

 

Treating and Preventing Halos and Glare

Depending on the cause of the halos or glare, you may be able to lessen its impact on your own. Or you may need the help of an eye doctor.

Some simple steps can reduce the effects of glare:

Sunglasses. Wear sunglasses to reduce glare during the daytime. Sunglasses that are polarized can keep certain types of glare from bothering your eyes, such as glare reflected from water.

Vehicle visor. Use your vehicle's visor to keep direct sunlight out of your eyes.

Lenses. Speak with your eye doctor about specialized lenses that may help correct the effects of glare due to abnormalities in the eye.

Treatment for halos and glare includes:

Fix your vision. If you have a vision problem in which your eyes don't focus light on your retinas properly, such as nearsightedness or farsightedness, wearing glasses or contact lenses can help.

Tell your eye doctor if halos or glare are bothering you. This will help the doctor find the right type of glasses or lenses for you.

Cataract treatment. Early in the development of cataracts, you may be able to reduce the effects of a cataract by using eyeglasses to improve your vision or by wearing sunglasses to lessen glare.

Surgery is a common, effective way to treat more serious cataracts. During the surgery, the eye doctor removes your cloudy lens and usually replaces it with an artificial lens.

Cataract replacement lenses called multifocal lenses may be more likely to cause halos and glares than monofocal lenses. Multifocal lenses help you see both near and distant objects.

Discuss the type of lens you need before the procedure. Ask your doctor about the risk of seeing halos and glare after the surgery.
