Maximizing Vision for Older Adults
Many older adults may notice that they have more difficulty seeing as well as when they were younger. This can affect their ability to enjoy activities such as reading and hobbies. It can also put people at greater risk for falls as they move about their surroundings. Older adults, when compared to middle-age adults:
· prefer at least three times more light for visual tasks;
· are more glare sensitive;
· have less ability to focus clearly at different distances;
· may not see as well in dim or nighttime situations.
Vision difficulties can occur for a number of reasons, including:
· The focusing lens in the eye (called the “crystalline” lens) becomes less flexible as we age. Over the age of 75, it also starts to yellow and becomes cloudier. This cloudy lens is referred to as a “cataract.”
· When the crystalline lens becomes cloudy enough to interfere with daily activities, an eye doctor can replace it with an artificial lens. In the United States, this is one of the most routine and effective eye procedures. However, most artificial lenses are inflexible and lack the ability to focus at different distances, so even after cataract surgery, a person will still need to find other ways to improve focusing ability.
· As we age, the gel-like capsule in the center of the eye (referred to as the “vitreous”) gradually develops an increase in “floaters.” These are usually pieces of protein that lose their clarity and can obscure or distract vision.
· Other age-related eye conditions such as macular degeneration, glaucoma and diabetic retinopathy, especially if untreated, may also decrease visual abilities.
So how can an older adult make the most of the vision that they have? Here are some simple tips:
· Schedule regular visits to an eye doctor as recommended to prevent vision loss. Also check with an eye doctor if any sudden changes in vision are noticed. Many eye problems are treatable, especially when they are detected early. Vision loss may develop so slowly that people can be unaware that they are seeing less and less.
· If recommended, wear eyeglasses. It is important to know which eyeglasses are for what tasks (driving, computer, reading, etc.), and how to use them correctly. Most reading glasses have an ideal reading distance. A person may want to move a book closer or farther away to see if it makes the print clearer.
· Good light shines on what a person is trying to see, and not in the person’s face. Arrange a desk lamp so that it is close (6 to 18 inches) to reading material. This increases the amount of light, and keeps the light shining primarily on the reading surface. Lighting mounted underneath a kitchen cabinet can illuminate a counter much better than overhead lighting. Think about desk lamp safety: Avoid heat-producing lamps that may cause burns or be a fire hazard, use a sturdy lamp that will not tip, and be sure cords are placed where no one can trip over them.
· Hard-back or large-print books may be easier to read for older adults than paperbacks and other reading materials that are printed on darker, recycled newspaper. Propping up a book at a comfortable reading angle using a pillow or a rolled-up towel can also improve reading ease.
· Simple, bold, large, well-spaced, block printing may be easier to read for some people than handwritten script.
· To reduce glare, arrange seating so that room lighting or light from windows is behind, rather than facing a person. Use window coverings such as adjustable opaque and gauze curtain combinations or blinds to minimize indoor glare.
· Night-lights, placed in outlets close to the floor near hazardous areas like stairs in the house, or on bathroom and kitchen counters can make travel in the home and finding things at night much safer and easier.
· A common, inexpensive 2X, hand-held, 3-inch round or 2-inch-by-4-inch rectangle, lighted magnifier can help an older adult to see small print and photos better. Find a magnifier that has a bright LED light, and batteries that are inexpensive, readily available and easy to change. Also, hands-free lighted magnifiers may help a person do needle-point or other hobbies.
· An inexpensive LED flashlight can help when a person needs to find items in a darkened cupboard or closet.
· A parasol, or a hat or visor with a brim can cut down on 50% of outdoor glare without reducing the light that is shining on what a person is trying to see. Additionally, an eye doctor can recommend sunglasses that can further reduce glare if necessary. Some non-prescription sunglasses are designed to fit-over prescription eyeglasses.
· Make good use of contrast throughout the home. For writing, use a medium-point black nylon-tip pen on white paper, rather than a blue or fine-point pen on colored paper. Put a light-colored plate on a dark-colored placemat to see the edge of a plate better. Use a light-colored plate when serving a dark-colored food, so that the food stands out on the plate. Place darker towels in a bathroom with light-colored paint, so that they are easier to locate in dim lighting. Mark a hand-rail that is the same color as the wall with bright tape to make it easier to find.
