Contact Lenses - A Non-Surgical Option For Better Eyesight
If the lenses of your eyes fail to focus images on your retinas, you've got the option of wearing glasses or contact lenses to see well. As you already know, glasses, which are the safest solution to correct refractive errors, improve eyesight by putting a lens in front of every eye. Eyeglasses for myopia refocus the light entering your eye with a concave lens (it bows inward) that is thinner in the center than around the edges. Simply put, such a minus lens - that subtracts power out of your optical system - "pre-spreads" the light, causing the rays of light to diverge before they go into your cornea. A minus lens transfers the focal point of an image from in front of the retina onto the picture receptors of the retina.
Eyeglasses and even cheap contact lenses correct farsightedness by refocusing the light that goes through your eye with a convex lens (it bows outward) that's thicker in the center than around the sides. Such a plus lens - which adds power to your optical system - "pre-bends" the light, causing the rays to converge more speedily before they enter your cornea. A plus lens brings the focus from behind the retina forward onto its photoreceptors.
Contact Lenses
Contact lenses can rectify eyesight by refocusing light through a transparent, hard or soft hydrophilic disk (one with a high water content) that floats on the surface of your own eye.
Similar to glasses, discount contact lenses for near- or farsightedness move the focal point of light, putting pictures directly on each retina. Rigid gas-permeable lenses (RGPs), usually provide better, crisper vision than soft contact lenses (SCLs). By making a spherical refracting surface, hard lenses can rectify not just near- and farsightedness, but also astigmatism. Many people however, are unable to tolerate hard lenses.
Most patients find SCLs A lot more comfortable compared with RGPs, but SCLs - which mold to the surface of the eye - usually fail to fix astigmatism. Even though specially-designed "toric" soft lenses correct astigmatism, not everyone will be able to wear them.
Allowing improved oxygen transmissibility, extended-wear soft contact lenses offer increased comfort and may be made to fix astigmatism. Disposable soft contacts, which many people cannot feel in their eyes, are exceptionally convenient because you could throw them away at the end of the day.
Regrettably, they fail to correct significant astigmatism. Interestingly enough, occasionally even a soft lens without toric correction could mask up to 1 diopter of astigmatism, depending on the contact's capability to hold its shape. Some soft lenses are thicker when compared to others. If a patient could put on a soft contact that has sufficient body. or "memory," even a sphere-shaped lens with no toric correction may offset low amounts of astigmatism.
