The clarity of our vision depends upon the shape of the eye. When a refractive error develops, the cornea is misshapen, making it difficult for the retina to focus on light rays properly. As a result, images nearby, far away, or both become blurry. Common refractive errors include nearsightedness, farsightedness, astigmatism and presbyopia.
Cascadia Eye offers treatment for each eye condition, giving you the opportunity to see much more clearly. The following information details a few of the most common visual conditions involving refractive errors. If you would like to schedule an eye examination to learn more about your eye health and ways to improve your vision, please contact us today.
Nearsightedness, also known as myopia, occurs when either the eye is too long from front to back or the cornea is too curved. As a result, light rays can’t be focused onto the retina – rather, they are focused in front of it. This eye condition causes you to see nearby objects clearly, while objects at a farther distance are blurry.
When you suffer from farsightedness, or hyperopia, nearby objects appear blurry and faraway objects are usually clearer. This is caused by the cornea not being curved enough or the eye being too short, which leads to light being focused past the retina.
A cornea with an irregular shape is considered to have astigmatism. Both nearby and faraway vision can be affected by the uneven cornea, as light cannot be focused properly. People with astigmatism experience vision that is blurred or doubled. Previously, laser surgery could not be done on those with astigmatism, but with today’s advancements in technology, astigmatism can now be corrected with lasers, such as through LASIK or PRK.
Starting around age 40, people typically begin experiencing the effects of presbyopia, influencing the need for reading glasses. With age the eye lenses begin to stiffen, making it more difficult for them to adjust focus to objects near and far away. The condition affects everyone to some degree with age, and it gradually worsens over time. Regular eye exams are necessary to diagnose and slow the progress of this common condition.
Cascadia Eye presents different options for restoring vision to patients suffering from the common eye conditions. In addition to temporary treatments, such as glasses and contact lenses, we also offer corrective refractive surgery through the following surgical methods:
While all of these solutions can provide great results, the best way to understand which is best for your situation is to meet with an eye care professional.
