Styes are a common eye issue caused by an infection of the eyelid glands. They appear as red, painful bumps on the eyelid and can be treated with warm compresses and antibiotics. GLAUCOMA (8 letters) is an eye condition that occurs when the pressure inside the eye increases, damaging the optic nerve and leading to vision loss. It is usually treated with eye drops, laser surgery, or medications. CATARACTS (9 letters) are a clouding of the lens of the eye, which can cause blurred vision and eventually lead to blindness. Surgery is the only way to treat cataracts.
