Cataracts refer to the condition in which the crystalline lens of the eye becomes opaque, resulting in a significant decrease in visual acuity. This opacity can interfere with the passage of light to the retina, leading to blurred or cloudy vision. Cataracts commonly develop with age, and factors such as prolonged exposure to sunlight, certain medical conditions, and smoking can contribute to their formation.

The other terms are related to different eye conditions: glaucoma involves increased pressure within the eye that can lead to optic nerve damage, macular degeneration affects the central part of the retina leading to loss of central vision, and retinal detachment is a serious condition where the retina separates from the back of the eye, potentially resulting in permanent vision loss. Each of these conditions has its own distinct causes and symptoms that differ significantly from those of cataracts.
