Farsightedness (hyperopia) is a common vision condition in which you can see distant objects clearly, but objects nearby may be blurry.
The degree of your farsightedness influences your focusing ability. People with severe farsightedness may see clearly only objects a great distance away, while those with mild farsightedness may be able to clearly see objects that are closer.
Farsightedness usually is present at birth and tends to run in families. You can easily correct this condition with eyeglasses or contact lenses. Another treatment option is surgery.
Farsightedness may mean:
· Nearby objects may appear blurry
· You need to squint to see clearly
· You have eyestrain, including burning eyes, and aching in or around the eyes
· You experience general eye discomfort or a headache after a prolonged interval of conducting close tasks, such as reading, writing, computer work or drawing
Your eye has two parts that focus images:
· The cornea, the clear front surface of your eye
· The lens, a clear structure inside your eye that changes shape to help focus on objects
· In a perfectly shaped eye, each of these focusing elements has a perfectly smooth curvature, like the surface of a marble. A cornea and lens with such curvature bend (refract) all incoming light to make a sharply focused image directly on the retina, at the back of your eye.
In young people, treatment isn't always necessary because the crystalline lenses inside the eyes are flexible enough to compensate for the condition. But as you age, the lenses become less flexible and eventually you'll probably need corrective lenses to improve your near vision.
Wearing corrective lenses treats farsightedness by counteracting the decreased curvature of your cornea or the smaller size (length) of your eye. Types of corrective lenses include:
· Eyeglasses. The variety of eyeglasses is wide and includes bifocals, trifocals, progressive lenses and reading lenses.
· Contact lenses. A wide variety of contact lenses are available — hard, soft, extended wear, disposable, rigid gas permeable and bifocal. Ask your eye doctor about the pros and cons of contact lenses and what might be best for you.
If you're also having age-related trouble with close vision (presbyopia), monovision contact lenses may be an option for you. With monovision contacts, you may not need correction for the eye you use for distance vision (usually the dominant eye). But a contact lens can be used for close-up vision in your other eye. Some people have trouble adapting to this kind of vision because 3-D vision is sacrificed in order to be able to see both nearby and in the distance clearly. Monovision contacts can be worn intermittently as desired.
Modified monovision contact lenses are another option. With this type of contact lens, you can wear a bifocal contact lens in your nondominant eye and a contact lens prescribed for distance in your dominant eye. You can then use both eyes for distance and one eye for seeing objects nearby.
