NEAR AND FAR—for improved focus and focusing speed when switching your gaze from close objects to distant objects (such as when checking gauges on a car as you drive). Preparation: Type a chart with six to eight rows of random capital letters, each letter about one-half inch tall (or as tall as necessary for you to read them from 10 feet away). Tack the chart to a wall and stand back 10 feet.
Exercise: Hold a pencil horizontally, with its embossed letters facing you, about six inches from your nose (or as close as possible without it looking blurry). Read any letter on the pencil, then read any letter on the chart. Keep doing this, switching back and forth as fast as you can without letting the letters blur. Over time: Do this with one eye covered, then the other.
PENCIL PUSHUPS—to promote eye teamwork. All you need is a pencil.
Exercise: Hold a pencil horizontally at eye level 12 inches from your face (or as far as necessary to see the pencil clearly). With both eyes, look at one particular letter on the pencil…keep looking while bringing the pencil closer to your face. If the letter blurs or doubles, it means that one eye is no longer accurately on target—so move the pencil back until the letter is clear once more…then try again to slowly bring the pencil closer while keeping the letter in focus.
THE “HOT DOG”—for improved flexibility of the muscles within the eye that allow the lens to change shape. No props are needed.
Exercise: With your hands at chest height about eight inches in front of you, point your index fingers and touch the tips together, so that your index fingers are horizontal. Gaze at any target in the distance and, without changing your focus, raise your fingers into your line of sight. Notice that a “mini hot dog” has appeared between the tips of your fingers. Still gazing at the distant object, pull your fingertips apart slightly—and observe that the hot dog is now floating in the air. Keep the hot dog there for two breaths…then look directly at your fingers for two breaths, noticing that the hot dog disappears. Look again at the distant object and find the hot dog once again. Continue switching your gaze back and forth every two breaths.
As your close-up vision improves, you may find that you need less-powerful reading glasses—or none at all—for your day-to-day activities.
