Blurry Vision and Light Halos: Eye Health Insights - Ophthalmology

Blurry vision and the perception of light halos around bright objects, such as streetlights or lamps, can be concerning symptoms for many individuals. These visual disturbances can stem from various underlying causes, and understanding them is crucial for maintaining eye health.

Firstly, the phenomenon you describe—seeing halos or a glow around lights—can often be attributed to several factors. One common cause is astigmatism, a refractive error where the cornea or lens is irregularly shaped, leading to distorted or blurred vision. This distortion can become more pronounced when viewing bright lights, especially at night, as the pupils dilate and allow more light to enter the eye. The result can be a halo effect around lights, which may appear elongated or stretched.

Another potential cause is dry eye syndrome. When the eyes are insufficiently lubricated, it can lead to visual disturbances, including blurriness and halos. Dry eyes can be exacerbated by environmental factors, prolonged screen time, or wearing contact lenses for extended periods. If you are experiencing dryness, it may be beneficial to use artificial tears or consult with an eye care professional for appropriate management.

Cataracts are another condition that can lead to similar symptoms. As cataracts develop, they cloud the lens of the eye, causing light to scatter and resulting in halos around lights, particularly at night. If you are experiencing blurry vision alongside halos, it may be worth discussing cataracts with your eye doctor, especially if you are over the age of 60 or have risk factors such as diabetes or prolonged steroid use.

Corneal issues, such as corneal edema or irregularities, can also cause halos and blurry vision. Conditions like keratoconus, where the cornea thins and bulges, can lead to significant visual distortions. If you have a history of eye surgery or trauma, these could also contribute to your symptoms.

In some cases, migraine aura can cause temporary visual disturbances, including halos and blurriness. If you experience these symptoms alongside headaches, it may be indicative of a migraine-related issue.

Given the variety of potential causes, it is essential to consult with an eye care professional for a comprehensive eye examination. They can perform tests to assess your vision, check for refractive errors, and evaluate the health of your eyes, including the cornea and lens. It is particularly important to rule out serious conditions like cataracts or corneal issues, especially if your symptoms persist or worsen.

In summary, experiencing blurry vision and halos around lights can be due to several factors, including astigmatism, dry eyes, cataracts, corneal irregularities, or even migraine auras. A thorough examination by an eye care professional is crucial to determine the underlying cause and appropriate treatment. Maintaining regular eye check-ups and addressing any changes in your vision promptly can help ensure your eye health remains optimal.
