Refractive errors

Refractive errors are vision problems that prevent seeing clearly. They occur due to the eye’s shape that hinders light from focusing correctly on the retina (the light-sensitive tissue later in the back of the eye).

Refractive errors are the most common vision problem, but most people with refractive errors do not know their vision could be better. This makes regular eye exams important. If you have a refractive error, your optician may recommend contact lenses or eyeglasses to improve your vision.

Types of refractive errors

Four common types of refractive errors affect people. They include:

Symptoms of refractive errors

Blurry vision is the most common symptom, but other symptoms are:

Some people may not notice refractive error symptoms, so ensure you visit your eye doctor for routine eye exams to ensure you are seeing clearly. You may need a new prescription if you wear contact lenses or glasses and still have the symptoms. Consult your eye doctor and get an eye examination if you have vision problems.

Can I have refractive errors?

Anyone can have a refractive error, but you have a higher risk if you have a family member that wears contact lenses or glasses.

Most refractive errors, like myopia, often start in childhood, while presbyopia is common in adults aged 45 and older. Speak to your doctor about your risk for refractive errors, and ask how often you should have your eyes checked.

Causes of refractive errors

How can my eye doctor diagnose refractive errors?

While conducting a comprehensive eye examination, your eye doctor can check for refractive errors. The examination is painless and simple. Your eye doctor will first ask you to read letters that are far away and close up, then give you some dilating eye drops to widen your pupil and check for other eye conditions.

Treatments for refractive errors

Your eye doctor can correct refractive errors with contact lenses, glasses, or surgery.

Discuss your options with your eye doctor. These tips are also important.
