With glaucoma, vision loss often starts at the edges (or periphery) of vision, and may advance to tunnel vision or blindness in serious cases.
Those with cataracts experience general vision cloudiness, making clear vision difficult. This represents a clear difference between glaucoma and cataracts distinction.

Types of Glaucoma vs. Types of Cataract
Types of Glaucoma
Types of Cataract
Open-Angle Glaucoma - The leading glaucoma type where eye drainage gradually declines, causing elevated internal pressure.
Nuclear Cataract - Located at the lens center, often related to getting older, causing gradual yellowing of click here the lens.
Angle-Closure Glaucoma - Sudden drainage angle closure between iris and cornea, requiring immediate treatment.
Cataract Treatment
Treatment for Glaucoma
Glaucoma is treated by lowering eye pressure through like prescription drops, laser options, or surgery. Glaucoma-related vision loss is permanent.
Cataract surgery involves replacing the clouded lens with an artificial one, restoring sight. This is safe and effective, unlike glaucoma treatments which can’t reverse damage.
