High-tech tools can help people with vision impairment. Examples include accessibility features (such as speech-to-text or text-to-speech) on a smartphone or computer; apps for navigation, magnification, or describing a scene; wearable devices that use video cameras to capture images and then project them onto tiny screens inside a headset; peripheral prism glasses, which shift light from one side of the eye to the other to make up for losses in field of vision; and household gadgets such as "talking" thermometers, scales, and calculators that audibly read out results.

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.

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.
