that 1 not farsightedness lah .....
Presbyopia is the name ....
Presbyopia is not a disease as such, but a condition that affects
everyone at a certain age. The first symptoms are usually noticed
between the ages of 40-50, though in fact accommodation reduces
throughout life, from about 20 dioptres (ability to focus at 50 mm
away) in a young person to 10 dioptres at 25 and levelling off at
0.5 to 1 dioptre at age 60 (ability to focus down to 1 -2 metres
only). 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
different from far-sightedness .....
i think farsightedness quite uncommon too ....
