What's the most common focusing problem?
The most common of all refractive problems is called
presbyopia - the inability to focus on small objects held close to
the eye. This occurs naturally in ALL people as a result of age,
and there's just no way to avoid it. During your 40s it may be
possible to just hold things farther away and use a stronger
light, but eventually you'll find that your arms aren't quite long
enough and the light isn't quite strong enough. At this point,
most people use reading glasses, bifocals, or progressive
spectacles. Presbyopia is due to the natural age related
changes to the lens of the eye and there's no way to avoid it.
