Seeing Halos and Starbursts Around Lights: Causes and Concerns - Ophthalmology

More Info

---

Seeing halos and starbursts around lights can be a concerning symptom, especially if it has persisted for an extended period. There are several potential causes for these visual disturbances, and understanding them can help determine whether they are merely a result of eye strain or indicative of a more serious underlying condition.

One common cause of halos and starbursts is refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. These conditions can lead to light being improperly focused on the retina, resulting in distorted images and halos around lights. If you have not had your vision checked recently, it may be worthwhile to schedule an eye exam to determine if a change in your prescription is necessary.

Another potential cause is dry eye syndrome, which can occur due to prolonged screen time, environmental factors, or certain medications. When the eyes do not produce enough tears or the tears evaporate too quickly, it can lead to discomfort and visual disturbances, including halos. If you have been using eye drops to alleviate redness, it is essential to ensure they are appropriate for your symptoms and not causing further irritation.

Cataracts are another condition that can cause halos around lights. This clouding of the lens in the eye typically occurs with age but can also develop due to other factors, such as prolonged exposure to UV light, certain medications, or underlying health conditions like diabetes. If you are experiencing other symptoms, such as blurred vision or difficulty seeing at night, it is crucial to consult an eye care professional for a thorough examination.

Glaucoma, a condition characterized by increased pressure within the eye, can also lead to visual disturbances, including halos. This condition can be asymptomatic in its early stages, making regular eye exams essential for early detection and management. If you have a family history of glaucoma or other risk factors, it is particularly important to have your intraocular pressure checked.

In some cases, migraines can cause visual disturbances, including halos and starbursts. These symptoms may occur with or without a headache and can be accompanied by other visual phenomena. If you have a history of migraines, this could be a potential explanation for your symptoms.

Given that you have been experiencing these symptoms for six months and have not seen improvement with over-the-counter eye drops, it is advisable to seek a comprehensive eye examination from an ophthalmologist. They can conduct various tests to assess your eye health, including checking for refractive errors, dry eye syndrome, cataracts, and glaucoma. Additionally, they can provide tailored recommendations for treatment based on the underlying cause of your symptoms.

In summary, while eye strain and fatigue can contribute to visual disturbances like halos and starbursts, it is essential to rule out other potential causes, especially if the symptoms persist. Regular eye exams are crucial for maintaining eye health and addressing any concerns promptly. If you notice any changes in your vision or experience additional symptoms, do not hesitate to seek professional medical advice.
