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.

Invisible illnesses, meaning those that aren't obvious to other people, affect an estimated 10% of the 61 million Americans who have a physical or mental condition that limits their movement or senses. Some people fear disclosing their invisible illness will make them seem incapable or entitled, but keeping illness secret can lead to isolation. People who decide to disclose their hidden illness should keep descriptions simple, point others toward reputable information, tell people how the illness limits them, and seek support.

What people choose to eat has a big impact on their cardiovascular health. The dietary habits of the nation as a whole also have a major effect on the country's economic health. About 45% of the costs associated with heart disease, stroke, and diabetes is related to unhealthy diets. The dietary habits that appear to have the biggest effect are not eating enough nuts, seeds, and seafood omega-3 fatty acids. Among foods to avoid, sugary beverages and processed meats seem to contribute the most to higher costs. Each year, unhealthy diets cost the United States an average of about $300 per person in medical costs, which translates to $50 billion nationwide.

Some research says taking a daily fish oil supplement can reduce the risk of heart attacks and strokes, while other studies say the evidence remains thin. While fish oil is the best source of omega-3 fatty acids (essential nutrients that the body cannot make on its own),  taking an over-the-counter fish oil supplement probably provides no extra heart benefit beyond a well-balanced diet that includes plenty of omega-3-rich fatty fish, nuts, and seeds.

A recent review found not only that coffee won't harm cardiovascular health or raise the risk of cancer, but it may actually have some health benefits. These include a lower risk of diabetes, and certain cancers, such as liver, and endometrial cancer. Many of these benefits may come from plant chemicals found in coffee.

Millions of Americans get sinusitis each year. The key to a quick recovery is proper drainage, which is best achieved by staying hydrated, inhaling steam several times daily, taking decongestants, and sleeping with the head elevated.

A new medication called dupilumab (Dupixent) may help reduce nasal polyps in people with recurring polyps and chronic sinusitis.
