It’s critical to wear proper sun protection to prevent serious damage caused by photokeratitis (and its painful symptoms). Other symptoms may include pain, redness, blurred vision and more.
Seeing halos around lights is one of the many symptoms associated with photokeratitis. The conjunctiva (which covers the surface of the eye and lines the inner eyelids) is also affected by the condition. These rays can damage the eyes - especially the thin surface of the cornea. Photokeratitis is a sunburn-like condition caused by too much exposure to ultraviolet (UV) rays. However, some research seems to indicate that an enzyme imbalance in the cornea could make it more vulnerable to oxidative damage. Some cases may require corneal cross-linking or a corneal transplant, however. This includes seeing halos around lights, light sensitivity, eye strain and trouble driving at night.ĭepending on the stage and degree of keratoconus, it can be treated with corrective lenses. This process can result in astigmatism, nearsightedness and severe vision impairment as time goes on.īecause the cornea is directly impacted by the condition, many of the symptoms are light related. This thinning can lead to a cone-shaped bulge in the eye. Keratoconus is a progressive eye condition that causes the naturally dome-shaped cornea to thin out over time. Posterior subcapsular cataracts have been known to progress more quickly than other types of cataracts, which can lead to further vision problems. It’s important to have an eye exam every year to rule out conditions such as cataracts, and even more important if the condition runs in your family. These cataracts may also cause glare or halos around lights, especially at night time. They can also interfere with your vision in brightly lit environments. Cataracts that affect the back of the lens (known as posterior subcapsular cataracts) can cause you to have trouble reading in dim light. There are many types of cataracts that can affect your vision in different ways. Recovery from vision surgery such as LASIK or cataract surgery What causes halos around lights?Īccording to the American Academy of Ophthalmology, seeing halos around lights may be associated with the following conditions: This could be due to an underlying condition that requires monitoring and treatment. Let your eye doctor or an ophthalmologist know if you suddenly start seeing halos, especially if they are accompanied by pain, redness, blurred vision or any other major symptoms. These can range from an outdated lens prescription to a condition that requires emergency treatment. Halos around lights can be a sign of both mild or severe eye issues. However, constantly seeing halos may be a concern worth raising to your eye doctor. It’s not unusual to see a circle or starburst radiating from a light source when you look directly at it.
