Know Your Vision Conditions: Hyperopia, Myopia and More

Did you know there’s more than one kind of vision problem you can have? Most people are familiar with nearsightedness. But, there are other conditions, like hyperopia, presbyopia, and astigmatism that can all affect your vision. Here’s what you need to know.

How Diagnoses Are Made

Nearly all eye doctors diagnose refractive errors (vision problems) by testing the refraction of your eye’s lens. Refraction is the bending of light as it passes through your eye. You see, your eye contains a lens which is often compared to a camera’s lens. As light passes through the lens, it bends and is focused on the back of the eye. In a camera, light hits a sensor. In your eye, light hits the retina.

The reason you’re able to see the world around you is because light rays are bent as they pass through the cornea and this bending of numerous rays of light causes those rays to all focus on a single point at the back of your eyeball.

The retina converts the light into messages that your brain then interprets as images.

When there is a problem with the light bending through the eye, then it is said that you have a refractive error or a vision problem. Thankfully there are ways you can get help with your vision. If you have issues with your eyesight you might want to visit somewhere similar to these focus clinics for help or information.

What Kind Of Errors?

There are several different kinds of errors you can experience. The most common is nearsightedness.

This condition, also called “myopia,” is a condition where things up close are in focus but objects far away are out of focus. With nearsightedness, the light bouncing off objects bends and ends up focusing in front of the retina, which produces a blurry image.

The cause is that the cornea is either too steep or the eyeball is irregularly shaped as a football instead of being more round.

According to the Laser Eye Surgery Hub, this type of vision problem can be easily corrected with laser surgery at a cost of about £1500. A variety of clinics offer this treatment, so if you are interested then contact someone like The Better You to discuss your treatment options.

Many doctors also prescribe eyeglasses or contact lenses to correct the refractive error without addressing the underlying cause.

Another problem is farsightedness. Farsightedness is also called hyperopia and is a refractive error that causes objects in the distance to be in focus while near objects are blurry. However, many people

experience farsightedness differently. For some, they don’t notice any problems with their vision. For others, they experience marked reduction in near vision.

An astigmatism is another condition where light bending at the cornea misses the retina and doesn’t focus evenly onto it. This can cause images to be blurry and stretched out at all distances.

Presbyopia is similar to farsightedness, but it’s something that happens to those who are older. It’s an age-related condition where your ability to focus up close is reduced because the lens of your eye has hardened and it won’t focus as it used to.

Who Is At Risk?

If you’re over the age of 35, you’re at an increased risk of presbyopia. Outside of this condition, the risk factors for vision problems depend on a variety of things, like genetics, and whether or not you perform a lot of near work. Since myopia is associated with both genetic predisposition and close work (e.g. reading), it’s thought that those who spend more time indoors reading, and who have a genetic predisposition to nearsightedness, may be at an increased risk for developing this type of refractive error.

  1. Lucy me! I have Hyperopia, Presbyopia, and an astigmatism. Without my glasses, I am probably legally blind. I am hoping that I will be a candidate for Lasik surgery so I can at least tell the difference between the shampoo and the conditioner in the shower! Yes, it’s that bad! LOL Thanks for the post!

  2. Too chicken to get Laser surgery, but am tired of my changing vision. Glasses for driving/TV and readers for reading…none of them work for being on a computer…it’s in between! Bifocals don’t work for me either. Ugh

  3. Our daughter was near sighted & it kept getting worse as she got older. The eye dr recommended lasik surgery. Her vision was corrected for 20 years & now she has to wear glasses while driving at night – night vision.

  4. I have had myopia since 10. I can not get laser eye surgery because I have dry eyes. I wish I could so I could have my vision improved. It can be a pain to wear glasses.

  5. Thanks for the explanation of these as now it is more clear to me what they are and how they can be helped. My cousin is like Edna above.

  6. I am so happy to see this info about vision problems! I have recently started having problems with my vision and this has helped me better understand what’s going on! Thank you so much!

  7. My Mum had laser surgery for cataracts when she was 80 & threw away all her glasses! She can’t believe the difference. Mind you, she can also see wrinkles that she never knew she had!

  8. I have extreme myopia (since 5th grade) and I would SO love to see without glasses! Contacts area hassle & I don’t want to do laser….
