Today we are looking
at long sighted people this condition is called hyperopia people with this
condition can see clearly things far away but things up close are blurry.
What causes this
condition well since it is the opposite of being short sighted the causes are
the opposite of those that, such as the eyeball being too short and the lens
too thin, with the shorter the eyeball and the thinner the lens the more long
sighted a person will be.
In a long-sighted
person light rays are not focused on the retina, the actual point of focus is
further away from the retina, so a blurred image forms on the retina.
Because of this, the
eye has to work harder to focus on near objects.
Those with long‑sightedness
often notice:
Blurry vision when
reading or doing close work
Eye strain or
headaches after focusing for a while
Squinting to see
clearly
Fatigue, especially
later in the day
Some children can
“auto‑focus” using their eye muscles, so the problem isn’t obvious until they
get tired.
This
condition is treated in a few ways such as glasses with convex lenses, contact
lenses and surgery.
As people age, the
lens becomes less flexible, making it harder to compensate for hyperopia.
That’s why many people find reading harder in their 40s and beyond.
