Commonly referred to as farsightedness, a patient with hyperopia will find it easy to see things far away, but experience difficulty with close-up vision. Hyperopia is caused by a refractive error in the eye.
In the eye, two parts are responsible for focusing: the cornea and the lens. These two parts work together to refract, or bend, incoming light. With a refractive error, incoming light is being improperly focused onto the retina. A misshaped cornea or a rigid lens can result in a refractive error.
Causes of Farsightedness
Farsightedness happens due to a number of different causes, such as: your eye being shorter than normal, the cornea being too flat, or the lens is positioned further back into the eye than normal.
Hyperopia usually begins during childhood. It is commonly missed due to the flexibility of the lens in young children. Hyperopia is not to be confused with presbyopia, which naturally occurs with age.
Signs and Symptoms of Hyperopia
Symptoms of hyperopia include blurry vision up close, squinting to see better, headaches after reading or other close-up tasks, and more. Symptoms of hyperopia are much like that of other refractive errors.
If a change in your vision is noticed, it is important to schedule an eye examination with our Optometrist. By doing so, they will be able to diagnose the problem relating to any symptoms being experienced.
How is Hyperopia Diagnosed?
Our Optometrist can diagnose hyperopia during a comprehensive eye examination. You will be asked to complete a standard vision test. The test consists of whether or not you can read letters on a chart placed at the other end of the room. Other tests and equipment are used to reinforce the diagnosis.
If the test concludes that you are farsighted, our Optometrist will use a phoropter to measure the amount of refractive error present.
Treatment for Hyperopia
Hyperopia can be treated with corrective lenses, or with refractive surgery. Eyeglasses or contact lenses are the most common method of treatment and work by refocusing light rays on the retina.
Refractive surgery, such as LASIK, are used to correct refractive errors by reshaping the cornea, and/or the front surface of your eye. Refractive surgeries decrease, or completely eliminate, the need for corrective lenses.
Suitable treatment options vary depending on the patient, and severity of refractive error present. Our Optometrist will be able to discuss the best method of treatment for you as well as address any other concerns you may have.
