Question: 1 / 400

What is the most common cause of halos around lights?

Mucous deposits on the cornea

Glaucomatous damage

Cataract formation

Halos around lights are primarily associated with the scattering of light, which can occur due to various eye conditions. Cataract formation is the most common cause of halos. As cataracts develop, they cause the lens of the eye to become cloudy, leading to light scattering and the appearance of halos around light sources, especially at night or in low light conditions.

In contrast, while mucous deposits on the cornea can impact vision, they are less commonly linked to the phenomenon of halos. Glaucomatous damage primarily affects the optic nerve and might lead to vision loss rather than halos, whereas retinal detachment typically leads to more acute symptoms such as flashes of light or sudden vision changes rather than the continuous appearance of halos. Thus, understanding the relationship between cataracts and the light scattering effect clarifies why this condition is the correct answer for the cause of halos around lights.
