Farsightedness or hyperopia, occurs when light
entering the eye focuses behind the retina, instead of
directly on it. This is caused by a cornea that is
flatter, or an eye that is shorter, than a normal eye.
Farsighted people usually have trouble seeing up close, but
may also have difficulty seeing far away as well.
Young people with mild to moderate hyperopia are often
able to see clearly because their natural lens can adjust, or
accommodate to increase the eye’s focusing ability. However,
as the eye gradually loses the ability to accommodate (beginning
at about 40 years of age), blurred vision from hyperopia often
becomes more apparent.
Signs and Symptoms
Difficulty seeing up close
Blurred distance vision (occurs with higher amounts of hyperopia)
Eye fatigue when reading
Eye strain (headaches, pulling sensation, burning)
Crossed eyes in children
Detection and Diagnosis
Hyperopia is detected with a vision test called a refraction.
Very young patients may require cycloplegic eyedrops prior to
this test so that they are unable to mask their farsightedness
The treatment for hyperopia depends on several factors such
as the patient’s age, activities, and occupation. Young patients
may or may not require glasses or contact lenses, depending on
their ability to compensate for their farsightedness with
accommodation. Glasses or contact lenses are required for older
Refractive surgery is an option for adults who wish to see
clearly without glasses. LASIK, clear lens replacement, LTK and
intraocular contact lenses are all procedures that can be
performed to correct hyperopia.
