What is Farsightedness?
Are you having trouble reading a book or focusing on objects near you but you are able to see distant objects clearly? You could be experiencing symptoms of farsightedness. Read on to find out more about the causes of farsightedness.
Farsightedness, also known as Hyperopia or Hypermetropia is one of the common refractive errors in which distant objects may be seen more clearly than near objects.
Causes and risk factors of Farsightedness
Farsightedness occurs when your eyeball is shorter than a normal person. This causes light entering your eyes to focus behind the retina, instead of directly on its surface.
While there are different causes for farsightedness, family history or heredity is usually the main reason. Hyperopia usually occurs at birth but can still develop in adulthood.
The most noticeable symptom is blurry vision when looking at objects up close. Other symptoms you may notice:
- Eyestrain or discomfort
- Squinting of eyes
- Eye discomfort or headache when performing tasks that require focus up close
- Difficulty reading
Blurry vision when focusing on near objects does not automatically mean you have farsightedness, it could mean something else.
If you are experiencing any visual blurriness, schedule an appointment with an eye care professional near you for a consultation.
Genetic factors are one of the causes of farsightedness in a child. Children may not be aware of their vision problems. As a parent, you should make sure to watch for the following signs:
- Eyestrain or headache when reading
- Difficulty reading and writing
- Rubbing of eyes and blinking frequently
- Esotropia (Common type of crossed eye in which one of the eyes is turned inwards)
When you have farsightedness, your prescription for your eyeglasses or contact lenses will be a positive number. The higher the number, the more nearsighted you are, i.e. +2.00 is stronger than +1.50. Farsightedness can be corrected with eyeglasses, contact lenses, or refractive surgery.
Eyeglasses for farsightedness is one way for a clearer vision. There are many types of lenses for you to choose from. To protect your eyes from permanent damages, consider getting a photochromic lens to protect yourself from UV rays, and filter harmful blue light from your digital screen. If you are over 40, you may need progressive lenses.
Do you have an active lifestyle such as participating in sports frequently? Do you simply prefer contact lenses over glasses? Contact lenses may be the better choice for you.
If you find wearing eyeglasses or contact lenses troublesome, refractive surgery such as Lasik or Photorefractive Keratectomy (PRK) may be another option.
- PRK flattens your cornea and allows light rays to focus closer on the retina.
- Lasik surgery creates a thin flap on the surface of your cornea and a laser is used to remove some corneal tissue, before moving the flap back into place.
Refractive surgery depends on the condition of your eyes and not everyone qualifies for it. Speak to an eye doctor today to find out more about refractive surgery.
