Which symptom is commonly associated with glaucoma?

• A. Blurred vision in one eye
• B. Redness and severe eye pain
• C. Halos around lights
• D. Hearing loss

Answer: (C)

Glaucoma involves damage to the optic nerve from increased intraocular pressure, and the symptoms can vary. Halos around lights is a classic sign you see with glaucoma, particularly when pressure spikes; the cornea can swell and refract light in a way that creates rings around bright lights. This makes halos around lights a distinctive symptom linked to elevated eye pressure and optic nerve stress.

Other options don’t fit as well. Blurred vision in one eye can occur with various conditions and isn’t specific to glaucoma. Redness with severe eye pain suggests an acute red-eye crisis like angle-closure, which is a separate and often emergent situation. Hearing loss is not related to glaucoma.
