Presbyopia the eye's diminished ability to focus that occurs with aging. This arises from the loss of elasticity of the eye’s lens. Presbyopia is a condition that affects everyone at a certain age. The first symptoms are usually noticed between the ages of 40-50, though in fact the ability to focus declines throughout life. For those with good distance vision, it may start with difficulty reading fine print, particularly if the lighting is poor, or with eyestrain when reading for long periods.
With presbyopia many people complain that their arms have become "too short" to hold reading material at a comfortable distance. Presbyopia becomes much less noticeable in bright sunlight. This is not the result of any mysterious 'healing effect' but just the consequence of the iris closing to a pinhole, so that depth of focus, regardless of actual ability to focus, is greatly enhanced, as in a pinhole camera. People often confuse presbyopia for hyperopia (long or far sightedness) as both will cause problems with near vision.
