WHAT CAUSES HALOS IN YOUR VISION?
Dr. Jim Martin 10/14/2015
While light is obviously crucial to our vision, how eyes absorb it can sometimes result in vision problems, such as halos. Halo are circles that appear around a bright source of light, like the headlights of an oncoming car. They happen most often at night, or in dim light, and can be a symptom of cataracts.
What Are Cataracts?
First, cataracts develop as we age and become more common after the age of 65. We will all develop them eventually. Cataracts form when the protein and water balance of your eye's lens becomes out of balance as the protein clumps up and clouds the lens. The thick protein blocks the light being absorbed by the lens, and a cloudy appearance develops. This is important because your vision depends on maintaining a correct balance of fluid and light absorption.
While cataracts tend to gradually get worse over time, they are not considered a medical emergency, but your vision will continue to deteriorate until you need cataract surgery.
What Are Symptoms Of Cataracts?
Typically, a cataract begins with small changes in how your eye absorbs light. The result can be halos, as mentioned, faded colors, or a reduction in your vision overall.
These changes become more of an issue as your vision becomes more obstructed. Other symptoms include poor night vision and extreme sensitivity to glare. Patients often describe the sensation as being similar to looking through a pair of dirty eyeglasses.
Cataracts can be detected through an extensive eye exam, which includes a microscopic examination of the inside of your eye.
How Is It Treated?
In the early stages of cataract formation changes in your eyeglass prescription will help with your symptoms. When the cataracts become advanced, cataract surgery is recommended. But surgery is typically delayed until the severeness of the obstruction interferes with day-to-day living.
