Understanding Halo Vision: Causes, Symptoms, And Treatment

What is Halo Vision?

Halo vision, also known as a halo around lights, is a visual phenomenon where a person sees a bright circle or ring around a light source. This can occur in one or both eyes and may be a sign of an underlying eye condition. In this article, we will explore the definition, causes, symptoms, and treatment options for halo vision, as well as tips for prevention and managing its impact on daily life.

Causes of Halo Vision

There are several potential causes of halo vision, including:

• Refractive errors: People with nearsightedness, farsightedness, or astigmatism may experience halo vision due to the way light is refracted in the eye.
• Cataracts: Clouding of the eye's lens can cause light to scatter, leading to the perception of halos around lights.
• Corneal abnormalities: Conditions such as keratoconus, where the cornea becomes thin and cone-shaped, can result in distorted light perception.
• Glaucoma: Increased pressure within the eye can affect the way light is processed, causing halos to appear.
• Other eye conditions: Certain eye infections, inflammation, or injuries may also contribute to halo vision.

Symptoms of Halo Vision

In addition to seeing halos around lights, individuals with halo vision may experience other symptoms such as blurry vision, difficulty driving at night, and sensitivity to light. It's important to consult an eye care professional if these symptoms persist or worsen.

Treatment Options for Halo Vision

The appropriate treatment for halo vision depends on its underlying cause. For refractive errors, prescription eyeglasses or contact lenses can help correct vision and reduce halo perception. Cataracts may require surgical removal of the clouded lens. In cases of glaucoma or other eye conditions, targeted medical or surgical interventions may be necessary.
