Contact Lenses - A Non-Surgical Solution For Better Eyesight
In case the lenses of your eyes fail to focus images in your retinas, you have the option of wearing glasses or contact lenses to see well. As you know, glasses, which are the safest option to correct refractive errors, enhance eyesight by putting a lens in front of every eye. Eyeglasses for myopia refocus the light getting into your eye with a concave lens (it bows inward) that's thinner in the middle than around the edges. Simply put, such a minus lens - which subtracts power out of your optical system - "pre-spreads" the light, which causes the rays of light to diverge before they go through your cornea. A minus lens transfers the focus of an image from in front of the retina onto the picture receptors of the retina.
Glasses and even cheap contact lenses correct farsightedness by refocusing the light that enters your eye with a convex lens (it bows outward) that's thicker within the center than around the sides. Such a plus lens - which adds power to your very own optical system - "pre-bends" the light, which causes the rays to converge more rapidly before they enter your cornea. A plus lens brings the focal point from behind the retina forward onto its photoreceptors.
Contact Lenses
Contact lenses may rectify eyesight by refocusing light through a transparent, hard or perhaps soft hydrophilic disk (one with a high water content) that floats on the surface of your own eye.
Like glasses, discount contact lenses for near- and farsightedness transfer the focus of light, putting pictures directly on each retina. Hard gas-permeable lenses (RGPs), usually offer clearer, crisper vision than soft contact lenses (SCLs). By creating a spherical refracting surface, hard lenses would rectify not just near- and farsightedness, but also astigmatism. Some people however, are not able to tolerate rigid lenses.
Most patients find SCLs more comfortable when compared to RGPs, however SCLs - which mold to the surface of the eye - typically fail to fix astigmatism. Even if specially-designed "toric" soft lenses correct astigmatism, not everybody can wear them.
Allowing increased oxygen transmissibility, extended-wear soft contact lenses offer improved comfort and could be made to fix astigmatism. Disposable soft contacts, which most people cannot really feel in their eyes, are very convenient because you can throw them away at the end of the day.
Sorry to say, they fail to fix significant astigmatism. Interestingly enough, now and again even a soft lens without toric correction could mask as much as 1 diopter of astigmatism, depending on the contact's capability to hold its shape. Some soft lenses are thicker than others. If a patient can put on a soft contact that has enough body. or "memory," even a round lens with no toric correction could offset low amounts of astigmatism.
