Farsightedness, known in the medical world as hyperopia, is a condition where an individual can see object in the distance clearly, while they struggle to see the objects close to them. Due to this, they strain a great deal when reading books or the newspaper. This can lead to headaches and tiredness of the eyes.
Farsightedness is a well recognised problem, and affects many people across the globe. Here we take a look at this condition in a little more details.
What is farsightedness?
In farsightedness, the eyeball is a little smaller than usual. The distance from the front of the eye to the back of the eye is shorter. Due to this, when an image is focused on the eyeball, it projects at a point beyond the retina. This means that the image will not be crystal clear but rather blurred instead.
Hyperopia is an inherited condition most of the time. The constant straining of the muscles around the eye can cause pain and fatigue to the eyeball. Following birth, babies and infants are inherently farsighted, meaning their eyeball is shorter than normal. As they grow older, the eyeball starts to grow to the right size, allowing the image to focus on the retina.
If the eyeball does not grow to the appropriate size by the age of 7 or 8 years, then it is likely the adults will develop farsightedness over a period of time. This will need correction of some sort.
Symptoms of farsightedness
Many a time individuals are not aware that they suffer from this condition. As time progresses, viewing objects close to the eye becomes harder and harder. The excess straining can cause the muscles to become fatigued, leading to headache and eye strain.
Treating the condition
A diagnosis of farsightedness can be easily made through a routine eye test at an optometrists or ophthalmologist’s office. Once made, the defect must be corrected appropriately.
Since the image is focused beyond the retina, corrections must be aimed at bringing this forward so that the image focuses directly on the retina. There are simple ways to correct the defect.
1.Glasses – Wearing simple prescription glasses is sufficient to correct hyperopia.
2.Contact lenses – In those wearing glasses who no longer wish to do so, contact lenses provide an easy solution for correction of vision.
3.Surgery – New surgical techniques are now available to correct farsightedness, but they can be rather expensive. The degree of correction obtained may not be equivalent to glasses or contact lenses. Furthermore, surgery carries risks. Laser surgery is emerging as a successful therapy, but more research regarding this is ongoing.
