In our 40s and 50s, we begin to experience the naturally frustrating effects of blurry near vision. Reading the newspaper, seeing the computer screen or sending a text message becomes a struggle. We end up depending more and more on reading glasses or contact lenses to see up close. This natural loss of reading vision is called presbyopia (prez-bee-OH-pee-ah), and it eventually affects all of us, even if we never needed vision correction before.
LASIK and PRK can correct eye problems such as nearsightedness, farsightedness and astigmatism. However, these optical conditions are fundamentally different from presbyopia, and often presbyopia gets confused with that of farsightedness (hyperopia) since they both affect a person’s near vision.
With presbyopia, the eye’s natural lens, which is normally stretchy and flexible, loses its elasticity and begins to stiffen. This stiffening reduces the eye’s ability to change shape in order to focus on near objects. This causes vision to be out of focus, making objects look blurry. To compensate, you move objects further away in order to focus and see more clearly.
Whereas with farsightedness (hyperopia), the loss of near vision is correlated with light not properly focusing on the retina, which makes objects appear blurry close up.
To correct vision loss due to presbyopia and rid the need for readers we offer our patients Three options: Raindrop Inlay, KAMRA™ Inlay or mono-vision.
