Contact Lenses - A Non-Surgical Option 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 already know, glasses, which are the safest way to correct refractive errors, enhance eyesight by putting a lens in front of every eye. Spectacles 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 - that subtracts power from your optical system - "pre-spreads" the light, which causes the rays of light to diverge before they go into your cornea. A minus lens moves the focus of an image from in front of the retina onto the image receptors of the retina.
Glasses and even cheap contact lenses correct farsightedness by refocusing the light that goes through your eye with a convex lens (it bows outward) that is thicker within the center than around the edges. 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 focus from behind your retina forward onto its photoreceptors.
Contact Lenses
Contact lenses may rectify eyesight by refocusing light through a clear, hard or perhaps soft hydrophilic disk (one with a high water content) that floats on the surface of the eye.
Like glasses, discount contact lenses for near- or farsightedness shift the focus of light, putting images directly on each retina. Hard gas-permeable lenses (RGPs), usually offer clearer, crisper vision than soft contact lenses (SCLs). By making a spherical refracting surface, rigid lenses would rectify not only near- and farsightedness, but also astigmatism. Most individuals however, are not able to tolerate rigid lenses.
Most patients find SCLs A lot more comfortable than RGPs, however SCLs - which mold to the surface of the eye - usually fail to correct astigmatism. Even if specially-designed "toric" soft lenses correct astigmatism, not everybody can wear them.
Allowing improved oxygen transmissibility, extended-wear soft contact lenses provide improved comfort and may be made to correct astigmatism. Disposable soft contacts, which most people cannot really feel in their eyes, are extremely convenient because you could throw them away at the end of the day.
Unfortunately, they fail to fix significant astigmatism. Interestingly enough, occasionally even a soft lens without toric correction would mask as much as 1 diopter of astigmatism, depending on the contact's potential to hold its shape. Some soft lenses are thicker than others. If a patient could wear a soft contact that has enough body. or "memory," even a sphere-shaped lens without toric correction could offset low amounts of astigmatism.
