6 Eye Symptoms and What They Could Mean
๐ค Glaucoma
Glaucoma occurs when fluid pressure increases in the eye, damaging the optic nerve. People with glaucoma can lose their vision and eventually become blind, and the disease is one of the leading causes of blindness.
Early treatment may help slow the diseaseโs progression and prevent vision loss. People can develop glaucoma at any age, but it usually affects older adults.
๐ค Cataracts
Cataracts are a clouding of the eyeโs lens, leading to blurry vision and eventual vision loss. They often develop as people age, when the proteins in the eye begin to clump together and cause cloudiness, making it difficult to see properly.
An estimated half of the population has had cataracts by their 80th birthday, and those who smoke, are obese, have high blood pressure, take certain medications, or have diabetes have a greater risk of developing them.
Other symptoms can include double vision, difficulty seeing at night, a โhaloโ that appears around lights, and seeing colors become faded or yellowed.
๐ค Conjunctivitis (pink eye)
Most commonly known by its nickname, pink eye. Although it can be hard to pinpoint the cause of conjunctivitis, this eye condition can be triggered by viruses, bacteria, allergens, chemicals, and even a loose eyelash or dirty contact lens.
Besides the classic pink or red color that develops in the eye, conjunctivitis can also cause swelling of the eyelids, watery eyes, itching, burning, crusting, or discharge. Pink eye caused by a virus or bacteria can also be contagious.
๐ค Macular degeneration
An eye disease that damages the central vision. Macular degeneration usually refers to age-related macular degeneration (AMD). There are two subgroups of AMD: wet AMD, which occurs when blood vessels grow under the retina; and dry AMD, which affects about 80% of all macular degeneration cases and occurs when the retina thins over time.
๐ค Sty
Sties are red, pimple-like bumps caused by a blockage in one of the eyelidโs oil glands. They usually appear on the edge of a personโs eyelid. The most common symptoms include a sensitivity to light, a sensation of grittiness, and watery eyes.
๐ค Red eye
When the blood vessels in the eye become swollen due to dryness, allergies, or infections like conjunctivitis, the eyes can appear red and bloodshot.
