Halo vision describes light sources, particularly street lights, appearing blurry or surrounded by a halo-like glow. If you’ve noticed this effect while driving or walking at night, it’s important to understand the underlying causes and seek appropriate care.
At Yesnick Vision Center in Las Vegas, we treat underlying eye conditions that cause halo vision. We also treat eye emergencies caused by injuries, sudden vision loss, and more.
Here’s everything you need to know about halo vision.
Causes of Halo Vision
The human eye is a complex organ that allows us to see by focusing light onto the retina — a thin layer of cells at the back of the eye that converts light into electrical signals that are sent to the brain.
Light needs to pass through several parts of the eye, such as the cornea, lens, and vitreous humor in order for you to see clearly. When this process is disrupted, light doesn’t pass through the eye properly, leading to halos appearing in your vision.
Halos are often caused by refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism, which occur when the shape of the eye prevents light from focusing correctly on the retina. Other causes of halo vision include cataracts, corneal edema (when the cornea becomes swollen and cloudy), glaucoma, chronic dry eye, keratoconus, fuchs’ dystrophy, and wearing multifocal lenses.
Diagnosis and Treatment of Halo Vision
If you have any symptoms of halo vision, be sure to visit an optometrist near you to rule out any underlying conditions that should be treated or corrected. They’ll conduct a comprehensive eye exam that can identify what’s causing your symptoms and create a tailored treatment plan for you.
For some patients with halo vision, prescription glasses or contact lenses can correct the issue. If there’s a medical condition triggering the halo vision, such as cataracts or glaucoma, treatment may involve surgery or medications.
Protecting your eyes from UV radiation by wearing sunglasses or a hat can also help prevent corneal edema and other eye conditions that can cause halo vision.
