What is a Refractive Error

A refractive error is a common eye disorder that affects many people. It’s when the eye cannot focus images correctly which results in blurred vision. If you think you have a refractive error it’s important to visit an optician as they can help correct the issue and prevent further damage. 

Corrective lenses are needed when you have a refractive error, as they can fix the problem, allow your vision to improve, and prevent visual impairment.

The 3 Types of Refractive Errors 

There are 3 main types of refractive error to be aware of. These are all very common and vary from person to person. If you have any of these then it’s important to get it checked out so you can get the right eye care for you.

Myopia: Myopia (short-sightedness) is where you struggle to see far away objects clearly. When trying to view things from a distance, you’ll find that your vision becomes blurred and you cannot focus on the thing clearly. This is myopia and it can easily be fixed with corrective lenses. 

Hypermetropia: Hypermetropia (long-sightedness) is quite the opposite of myopia. Hypertropia is when you cannot see objects close to you clearly. Again this refractive error is common and can be treated quickly with contact lenses or glasses.

Astigmatism: Astigmatism is a common refractive error that causes your vision to be blurred, especially in low light situations. Characterized by blurry vision and glares, this condition can vary in severity but can be fixed through corrective lenses. 

What Causes a Refractive Error?

So now that we know what a refractive error is and the three main types, what causes these to occur? 

Refractive errors are caused by an irregular eyeball length. People without a refractive error have a round eyeball shape, whereas those with the condition have a misshapen eyeball length (being too long or short). 

This causes light to not bend and focus as it should onto the retina. Resulting in the symptoms of refractive errors. 

Should I See an Optician?

If you have symptoms of a refractive error such as blurry vision and not being able to focus on objects near or far from you, then you should contact your optician. Your optician can perform an eye examination on you and prescribe you corrective lenses that will help improve your vision and prevent any serious eye conditions from occurring.
