If the lenses of your very own 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 method to correct refractive errors, improve eyesight by putting a lens in front of each eye. Glasses for myopia refocus the light entering your eye by using 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 from your optical system - "pre-spreads" the light, causing the rays of light to diverge before they enter your cornea. A minus lens shifts the focal point of a picture 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 is thicker in the middle than around the edges. Such a plus lens - which adds power to your optical system - "pre-bends" the rays of light, causing the rays to converge more speedily before they reach your cornea. A plus lens brings the focus from behind your retina forward onto its photoreceptors.
Contact Lenses
Contact lenses can correct eyesight by refocusing light through a clear, hard or soft hydrophilic disk (one with a high water content) which floats on the surface of your own eye.
Similar to spectacles, discount contact lenses for near- or farsightedness shift the focal point of light, placing images directly on each retina. Rigid gas-permeable lenses (RGPs), normally provide better, crisper vision compared with soft contact lenses (SCLs). By making a spherical refracting surface, rigid lenses can correct not only near- and farsightedness, but also astigmatism. Many people though, are unable to tolerate hard lenses.
Many patients find SCLs A lot more comfortable than RGPs, but SCLs - which mold to the surface of the eye - often fail to rectify astigmatism. Even though specially-designed "toric" soft lenses fix astigmatism, not everyone will be able to wear them.
Allowing improved oxygen transmissibility, extended-wear soft contact lenses provide increased comfort and can be made to rectify astigmatism. Disposable soft contacts, which many people can't feel in their eyes, are particularly convenient because you could throw them away at the end of the day.
Sadly, they fail to correct significant astigmatism. Interestingly enough, every now and then even a soft lens without toric correction would mask up to one diopter of astigmatism, depending on the contact's capability to hold its shape. Some soft lenses are thicker when compared to others. When a patient could wear a soft contact that has sufficient body. or "memory," even a spherical lens without toric correction may offset low amounts of astigmatism.
