What eye condition may be associated with halos around lights?

Halos around lights are typically associated with conditions that affect the lens of the eye or the pressure within the eye. In particular, cataracts can cause a scattering of light as it passes through the cloudy lens, leading to the perception of halos. Similarly, glaucoma can increase intraocular pressure, which can also alter the way light enters the eye and is perceived, resulting in halos around lights.

Cataracts involve the gradual clouding of the crystalline lens, which can distort light and create visual phenomena such as halos, especially at night or in low-light conditions. Glaucoma, on the other hand, is characterized by increased pressure within the eye, which can lead to optic nerve damage and may also contribute to visual disturbances, including seeing halos.

Other conditions listed, such as macular degeneration, retinal detachment, and dry eye syndrome, do not typically cause halos as a prominent symptom. Macular degeneration primarily affects central vision, whereas retinal detachment can lead to symptoms like flashes and floaters rather than halos. Dry eye syndrome causes discomfort and visual disturbances due to lack of moisture but is not specifically linked to halos.
