Glaucoma is an eye disease that can cause permanent vision loss if not detected and treated early. Often called the "silent thief of sight," it usually develops slowly and without warning signs until significant damage has already occurred. Glaucoma affects the optic nerve—the vital link between your eye and your brain—and can impact anyone, although certain factors like age, family history, and genetics increase the risk. Regular eye check-ups and greater awareness about genetic risks are key to protecting your vision.
