Diopter lens
Wear eyeglasses? Want to shoot photos without them? Buy a digital camera with an adjustable diopter lens. Slight adjustments can improve clarity and sharpness when looking through the viewfinder.
An adjustable diopter lens, part the viewfinder on many digital cameras, lets you focus the viewfinder to match to your eyesight, be it nearsightedness or farsightedness. The dial is located near the viewfinder.
By rotating a dial, knob or slider, the image on the viewfinder will come in and out of focus. Make adjustments while looking through the viewfinder. Stop adjusting when the scene is sharpest. If your camera has focus brackets, keep your eye on them until they come into focus.
A word of caution
Be careful not to stick your finger in an eye while making diopter adjustments. Yup, it really happens!
