By age 75, about half of all Americans develop at least one cataract, a cloudy area in the eye's lens that can make it harder to read, do handiwork, golf, or drive. Stopgap measures—such as using brighter lights, avoiding nighttime driving, or wearing tinted glasses to reduce glare—can delay the need for cataract surgery. Cataract surgery has evolved to offer a variety of artificial lens options to replace the natural lens removed. Most lenses can reduce the need for glasses or contact lenses. People should check their health insurance coverage since most advanced lenses aren't covered.

Floaters are shadows that develop in people's field of vision and become more noticeable in certain light. Aging, cataract surgery, and being nearsighted make floaters more likely.

A pre-surgery consultation with the surgeon can feel overwhelming. Many people are anxious and have questions about what's to come. Setting the right expectations on both sides can ease anxiety and help define a successful outcome.

In a large 2022 study, people with unhealthy sleep patterns (those who snored, experienced daytime sleepiness, had insomnia, slept less than seven hours per night, or slept more than nine hours per night) were more likely to develop glaucoma than people with healthy sleep patterns.

Nearsightedness is a growing problem worldwide. While genes and developmental factors play a role in whether a child becomes nearsighted, research suggests that spending time outdoors can lower a child's risk of developing this condition.

Dry eye disease can redden eyes and make them sting, burn, or hurt. Relief may require a combination of strategies.

Nearly half of all people with inflammatory bowel disease have symptoms that occur outside of the gastrointestinal tract. These conditions, known as extraintestinal manifestations (EIMs), can affect the musculoskeletal system, eyes, lungs, and other areas of the body.

Ten years of data suggest that AREDS2 supplements are associated with a reduced risk of macular degeneration progression without any increase in lung cancer risk, according to a follow-up study published online June 2, 2022, by JAMA Ophthalmology.

Some people with newly diagnosed mild to moderate open-angle glaucoma have another option for first-line treatment. Instead of using prescription eye drops initially, they can have a laser procedure called selective laser trabeculoplasty (SLT). SLT uses light pulses to help clean up debris clogging the eye's natural drains. Clogged drains lead to elevated eye pressure that damages the optic nerve. SLT's effects wane after three to five years, at which point it may be necessary to have the procedure again, or to begin using eye drops to treat glaucoma.

Around menopause, a decline in estrogen can trigger low-grade inflammation that leads to unexpected symptoms from head to toe. Symptoms can affect the digestive tract, skin, joints, eyes, ears, and heart, among other areas. A 2022 study found that estrogen loss can even fuel the jaw pain known as temporomandibular disorder. A year or longer can pass before many women connect symptoms with menopause. Women can take lifestyle measures to lower inflammation, such as eating more fruits and vegetables, avoiding processed foods, and exercising.
