Refractive Errors

A refractive error is a vision condition that makes it hard for the retina to properly focus light rays. When the eyes are irregularly shaped, this can cause a problem with the way they are able to bend (refract) rays of light onto the retina, leading to refractive errors such as nearsightedness, farsightedness, astigmatism, and other conditions. Here at Gordon Schanzlin New Vision Institute, we offer a comprehensive selection of advanced procedures, including LASIK laser vision correction and implantable contact lenses, to improve refractive errors and help you see clearly without heavy reliance on corrective eyewear.

Below, you’ll find descriptions of some of the most common refractive eye conditions. If you would like more information, or if you would like to schedule an eye evaluation with one of our experienced ophthalmologists, please contact us today.

Myopia (Nearsightedness)

When the eye is too long or the cornea too steep, myopia can often result. Commonly known as nearsightedness, this condition causes objects at a far distance to appear blurry, while those at a near distance look perfectly clear.  

Hyperopia (Farsightedness)

Hyperopia, or farsightedness, is caused by an irregular curvature of the eye’s cornea. It can also result from the cornea being too short. These conditions can lead to the retina being bypassed while trying to focus light. Ultimately, farsightedness causes distant objects to be seen clearly, while up-close objects appear blurry.


Presbyopia is a condition that often affects people over 40. Many individuals begin to lose their ability to clearly see objects at a close distance during this period in life, and often require bifocals or trifocals to read, drive, and engage in other activities. We offer a range of treatment options that can address presbyopia and minimize the need for glasses or contact lenses.

Dysfunctional Lens Syndrome (DLS)

The eye’s natural lens begins to change as we grow older, often leading to a gradually decreasing ability to focus clearly on what we see. Known as Dysfunctional Lens Syndrome, this process typically begins with presbyopia in your 40s and eventually cataracts later in life. Dysfunctional Lens Syndrome is a symptom of natural aging and affects most, if not all, individuals; however, Gordon Schanzlin New Vision Institute offers state-of-the-art treatment options to significantly reduce its effects and have you seeing clearly for as long as possible.


The eye’s cornea is normally shaped like a sphere; however, a common condition known as astigmatism gives the cornea an uneven form, often resembling the shape of a football. Astigmatism can cause problems focusing on both near and faraway objects, leading to double-vision or blurry vision. While astigmatism was traditionally not treatable with laser vision correction surgery, that is no longer the case. Both LASIK and PRK procedures can effectively treat astigmatism and provide a much clearer view.
