Farsightedness, also known as hyperopia, is a common eye condition that causes blurry vision at close range. It is a refractive error, which means that the eye does not bend (refract) light correctly.
In farsightedness, light rays focus behind the retina, the light-sensitive tissue at the back of the eye. This is because the eyeball is too short, the cornea (the clear front part of the eye) is too flat, or the lens inside the eye is not strong enough.
Farsightedness is usually present from birth, but it may not cause noticeable vision problems until later in life, especially after age 40. This is because the eye’s focusing muscles are stronger when we are younger and can compensate for the refractive error.
Symptoms of farsightedness
The most common symptom of farsightedness is blurred vision at close range. Other symptoms may include:
- Eye strain
- Difficulty reading or doing other close-up work
- Double vision
- Burning or tired eyes
Treatment for farsightedness
Farsightedness can be corrected with eyeglasses, contact lenses, or surgery.
- Eyeglasses and contact lenses can bend light rays so that they focus correctly on the retina.
- Refractive surgery can change the shape of the cornea or lens so that light is focused correctly on the retina.
The best treatment for farsightedness depends on the individual’s needs and preferences. An eye doctor can help you choose the best treatment option for you.
If you think you may be farsighted, it is important to see an eye doctor for a comprehensive eye exam. Early diagnosis and treatment can help prevent vision problems from developing.
