Seeing Halos at Night? Here’s Why and What You Can Do

Title: Understanding Halos Around Lights: Causes and Treatment OptionsHave you ever noticed a hazy, rainbow-like ring surrounding lights, such as street lamps or car headlights? These optical phenomena, commonly known as halos, can be quite perplexing.

However, they often have an underlying cause and can serve as a sign of an eye condition or other issues affecting your vision. In this article, we will explore the various causes of halos around lights, from common conditions like cataracts and astigmatism to more rare occurrences such as chlorinated water exposure and vision surgery recovery.

Let’s dive in and unravel the mystery behind these intriguing visual disturbances. 1.

Cataracts:

Halos around lights are a common symptom of cataracts, a condition characterized by the clouding of the eye’s natural lens. As the cataract progresses, it scatters light entering the eye, causing glare and diffraction.

This scattering effect creates halos around bright lights, especially in dimly lit environments. Cataracts typically develop slowly over time, leading to progressively blurred vision, increased sensitivity to light, and reduced color perception.

Early diagnosis and timely treatment, usually through cataract surgery, can help restore clear vision and alleviate the associated halos. 2.

Keratoconus:

Keratoconus is a progressive eye disorder that causes the cornea to thin and become cone-shaped, leading to astigmatism and distorted vision. This condition can cause halos around lights, especially at night, due to the irregular shape of the cornea.

Additionally, individuals with keratoconus may experience increased light sensitivity, eye strain, and blurred vision. Corrective lenses, such as glasses or specially designed contact lenses, can help improve vision and minimize the presence of halos.

3. Photokeratitis:

Excessive exposure to ultraviolet (UV) radiation, either from the sun or artificial sources like tanning beds, can cause photokeratitis.

This condition is essentially a painful sunburn of the cornea, resulting in temporary vision disturbances, including halos around lights. Other symptoms may include eye pain, redness, tearing, blurred vision, and sensitivity to bright light.

Treatment typically involves using lubricating eye drops, wearing sunglasses, and avoiding further UV exposure until the cornea heals. 4.

Closed-angle Glaucoma:

Closed-angle glaucoma, also known as angle-closure or narrow-angle glaucoma, occurs when the drainage angle of the eye becomes blocked, resulting in a sudden increase in eye pressure. This emergency eye condition can cause intense pain, vision loss, and a classic symptom of rainbow-colored halos around lights.

If left untreated, closed-angle glaucoma can lead to permanent vision damage. Immediate medical attention is crucial, and treatment usually involves medications to lower eye pressure and sometimes surgery.

5. Fuchs’ Dystrophy:

Fuchs’ dystrophy is a progressive disorder that affects the cornea, leading to its swelling and a subsequent decline in vision.

Alongside other symptoms, such as discomfort, cloudy vision, and glare, individuals with Fuchs’ dystrophy may experience halos around lights, particularly in low-light conditions or when waking up. While there is no cure for Fuchs’ dystrophy, certain interventions, such as the use of eye drops and corneal transplant surgery, can help manage and slow down the progression of the disease.

6. Pigment Dispersion Syndrome:

Pigment dispersion syndrome occurs when pigment flakes from the iris accumulate and clog the eye’s drainage system, leading to increased eye pressure.

This condition often manifests with symptoms like halos around lights, blurry vision, and mild eye discomfort. Regular eye examinations and appropriate treatments, including eye drops and laser procedures, can help manage the condition and prevent further complications.

7. Dry Eye Syndrome:

Dry eye syndrome occurs when there is an inadequate production of tears or an imbalance in the tear film components, resulting in dryness, redness, and ocular discomfort.

People with dry eye syndrome may also experience light sensitivity and halos around lights, especially in dry environments. Treatment options include the use of artificial tears, lifestyle modifications, and prescription medications to alleviate symptoms and improve tear production.

8. Astigmatism:

Astigmatism is a refractive error caused by an irregularly shaped cornea or lens, which affects the way light is focused on the retina.

This condition can cause blurred vision at any distance, and individuals with astigmatism may notice halos around lights, particularly during night driving. Corrective measures, such as glasses, contact lenses, or refractive surgery, can help compensate for the irregular curvature and improve overall visual acuity.

9. Incorrect Vision Prescription:

Wearing an outdated or incorrectly prescribed vision prescription can lead to various visual disturbances, including blurred vision and headaches.

In some cases, these inaccuracies can also cause halos around lights. Regular eye examinations and ensuring the correct prescription are crucial for maintaining optimal visual function.

10. Chlorine Exposure:

Exposure to excessive chlorine, particularly in swimming pools, can lead to the destruction of the tear film, resulting in symptoms such as redness, dryness, and discomfort.

This chlorine-induced eye irritation can manifest with halos around bright lights, making vision appear hazy. Proper eye protection, seeking fresh air, and using lubricating eye drops can often alleviate these symptoms.

11. Vision Surgery Recovery:

Recovering from vision surgeries like LASIK or cataract surgery can involve temporary visual disturbances, including halos around lights.

These halos usually diminish as the eyes heal and adjust. It is essential to follow post-operative instructions, use prescribed eye drops, and attend follow-up appointments to ensure a successful and smooth recovery process.

12. Corneal Edema:

Corneal edema refers to the swelling of the cornea caused by excess fluid accumulation.

Common causes include trauma, certain eye conditions, or complications from surgery. In addition to blurred vision and light sensitivity, corneal edema may lead to halos around lights due to light scattering caused by the irregularities on the swollen cornea’s surface.

Treating the underlying cause and managing corneal edema often involves using medicated eye drops and sometimes addressing the underlying condition through surgical intervention. Conclusion:

Halos around lights can be indicative of various eye conditions or factors affecting visual clarity.

If you experience persistent halos or any other visual disturbances, it is crucial to consult an eye care professional for an accurate diagnosis and appropriate treatment. By understanding the underlying causes behind these halos, individuals can seek timely intervention and maintain healthy vision for years to come.
