Refractive errors
On this page, you will find everything you need regarding refractive errors.
What are refractive errors?
Refractive errors are among the most common eye problems. They are a type of vision issue that causes blurred vision. Refractive errors occur when the shape of the eye is abnormal, preventing it from bending light correctly, which results in blurry and unclear vision.
- There are several types, including:
- Hyperopia (Farsightedness): Distant vision is clear, but near vision is blurred.
- Myopia (Nearsightedness): Near vision is clear,stigmatismbut distant vision is blurred.
- Astigmatism: A problem with the curvature of the cornea causes both near and far vision to be unclear.
Presbyopia: This condition affects the elderly, making the eye less capable of focusing with age. A person with presbyopia notices that reading and focusing on close objects becomes more difficult, although distant vision remains clear.
- What are the symptoms of refractive errors?
- Blurred vision.
- Double vision.
- Seeing glare when looking at bright lights.
- Headaches around the eyes.
- Eye fatigue and strain.
Difficulty concentrating when reading or looking at a computer.
What are thecauses ofrefractive errors?.
Anyone can suffer from one of the refractive errors, but some factors increase the likelihood. A person is more susceptible if there is a family member with one of the refractive errors.
- Refractive errors can be caused by:
- A decrease or increase in the length of the eyeball.
Changes in the shape of the cornea.
What are the diagnostic methods?
Your doctor will ask you to read a chart with letters from far and near. They may then put dilating drops in your eye and conduct a simple and painless eye examination.
What are the treatment methods for refractive errors?:
- Treatment can be carried out through several procedures, as needed, and may include:
- Prescription glasses.
- Contact lenses.
-
- Surgery:
- LASIK/Laser surgery.
Intraocular lens implants.
What are the prevention methods for refractive errors?
Usually, there is nothing you can do to prevent refractive errors. Since they result from the shape of the eye, the cornea, or the lens, or from changes that occur to these parts of your eyes, there is no way to prevent refractive errors.
What are the complications of refractive errors?
- If you have a refractive error, you are more likely to suffer from other conditions that affect your eyes, including:
- Glaucoma.
- Lazy eye (amblyopia).
- Strabismus.
Visual impairment.
When should you see a doctor?
If you notice any symptoms of refractive errors in yourself or your child, you should see an ophthalmologist.
