👉 Glaucoma (also known as hypermetropia) is a condition where there's too much light in the eye. This can cause blurry vision, increased sensitivity to bright lights, and difficulty seeing at night or when it's dark outside. Glaucoma can be caused by a buildup of fluid in the eye called aqueous humor, which can lead to damage to the optic nerve or retina. If left untreated, glaucoma can lead to blindness.
