A refractive error refers to a change in the shape of a person’s eye that may cause their vision to become blurred.
Refraction is what enables us to see, when you look at an object, light reflects off its surface and is refracted through your cornea and retina enabling your brain to recognize the images around you.
Refractive errors compromise your ability to see as your eye is unable to bend and focus light appropriately onto your retina, resulting in blurry, hazy, or double vision. Refractive errors can occur at any age, affecting a child’s learning ability or preventing an adult from working effectively and safely.
Here at Eye Associates of Elkins Park, our optometrists will conduct a throughout eye and vision examination to determine the type of refractive error that affects your vision to prescribe the best treatment option.
Common refractive errors include:
- Myopia – often called nearsightedness, as patients with this refractive error have trouble seeing distant objects clearly. This occurs when the eyeball has a more elongated shape or if there is too much curvature causing the light to be refracted in front of the retina instead of onto the retina.
- Hyperopia – also known as farsightedness where patients can see distant objects clearer than nearby objects. However, if the hyperopia condition is significant, vision may be blurry at any distance. This is a result of the light being refracted behind the retina instead of to the retina due to the eyeball being too short or not having enough curvature on the cornea.
- Astigmatism – In patients diagnosed with astigmatism, the cornea may not be shaped like a sphere causing the light to be distorted and refract onto multiple points of the retina as opposed to just one area.
- Presbyopia – As you age, you may notice your ability to focus on close work worsen. This typically occurs after the age of 40 as the eyes’ lenses gradually lose their ability to focus and adjust light onto the retina. This condition should not be confused with macular degeneration, which occurs due to ocular damage to part of the eye.

The field of optometry changes quickly, and now many more patients are able to enjoy the flexibility of wearing contact lenses to correct their vision. Computer Vision This allows us to schedule the extra time required for contact lens fitting or prescription updates.
Scheduling your general eye exam and your contact lens exam for the same visit will save you time and money. Performing these exams at different locations or with different optometrists can lead to repeated tests and additional fees.
Our contact lens exams include questions about your lifestyle and the various options available to you. There are a variety of contact lenses on the market that can be changed at different frequencies: daily, weekly, monthly. Rigid gas permeable (RGP or GP) contact lenses are an option that often provide sharper vision than traditional soft lenses. Bifocal contact lenses are an option to correct vision issues that develop with age (presbyopia). So is monovision, which is a special technique where one eye corrects for distance vision and the other eye corrects for near vision. Some contacts even allow you to change eye color.
