Which of the following is a common symptom associated with glaucoma?

Peripheral vision loss is a common symptom associated with glaucoma because it typically affects the peripheral (side) vision first before impacting central vision. Glaucoma often results from increased intraocular pressure that damages the optic nerve, which transmits visual information from the eye to the brain. As the disease progresses, it can lead to significant vision impairment and ultimately blindness if not treated.

The other symptoms listed are generally associated with different eye conditions. Night blindness is often linked to conditions affecting the retina, such as retinitis pigmentosa or vitamin A deficiency. Color blindness is usually a genetic condition affecting the cones in the retina responsible for color vision. Blurry vision in sunlight could be attributed to glare or other refractive issues rather than glaucoma itself. Thus, while these other symptoms might indicate different visual impairments, peripheral vision loss is specifically indicative of glaucoma.
