Many people are inflicted with a sight disability known as astigmatism, a condition in which the cornea of the eye is curved irregularly, leading to vision reduction. One of the best solutions to this problem is to obtain special contact lenses...
Toric contact lenses correct a common eye condition called astigmatism. The American Optometric Association describes astigmatism as a vision problem caused either by an irregular shaped cornea, which is the clear outer layer of the eye, or...
Astigmatism, which is an irregular curve of the cornea, is so common that more people have it than don't have it. The University of Michigan's Kellogg Eye Center notes that astigmatism is not a disease, but rather a visual disturbance caused by...
Toric contact lenses are usually prescribed to correct astigmatism, a common vision problem. Toric lenses have special curves to help compensate and correct for astigmatism.
Toric contact lenses, designed for people who have astigmatism (irregularly shaped cornea), are similar to ordinary soft and RGP (Rigid Gas Permeable) lenses. In fact, the only difference is the shape. Toric contact lenses curve at different...
Astigmatism is a very common visual disorder created by abnormal or irregular curvature of the cornea, which causes light to bend irregularly as it passes through the lens of the eye, generating distortions in the formation of the visual image on...
According to the University of Michigan Kellogg Eye Center, astigmatism usually occurs when the front of the eye -- the cornea -- is curved more in one direction than the other. The resulting distortion in one's vision is much like looking in a...
A cataract describes a clouding of the eye lens, which focuses images on the nerve tissue at the back of the eye. A significant cataract causes loss of visual clarity and dimmed vision. The definitive treatment for a cataract is the removal of the...
A contact lens is a thin piece composed of various plastics placed directly over your pupil to correct nearsightedness, farsightedness or astigmatism. There are many different types of contacts, including Toric (for astigmatism), bifocal (for...
In people with the eye disorder astigmatism, the light coming into the eye becomes focused in two places instead of being pinpointed down to a single spot at the back of the eye. This can induce blurry vision, headaches and eye strain. Astigmatism...
Imagine a world where your vision is blurry. You go to the optometrist and are diagnosed with astigmatism, a defect in the cornea (surface layer of the eye) that can wreak havoc on your vision. You refuse to wear glasses and your doctor provides...
Focus contact lenses include the DAILIES line produced by Ciba Vision. DAILIES are disposable lenses designed to wear for one day. Focus contacts also are available in weekly or monthly disposable versions. The lenses are made with a moisturizing...
Toric contact lenses correct astigmatism caused by a slightly irregular-shaped cornea. They differ from regular lenses in that toric contact lenses have two powers: one to correct astigmatism, the other to correct near-sightedness or...
Aspheric contact lenses are a newer design concept, filling a niche for clearer, crisper vision for certain patient populations. From the early days of hard, unbreathable lenses to the highly oxygen-permeable soft contact lenses of today, aspheric...
Eyes become irritated for a variety of reasons, including dust, smoke, lack of oxygen to the eye surface, eyelid abnormalities, allergies and inability to produce adequate lubrication. People with sensitive eyes may find it difficult to wear...
Soft contact lenses are the most popular type of contact lens prescribed in the United States. Toric contacts are a type of lens that corrects for astigmatism, a common vision problem. Any type of contact lens may become dried out or feel stuck on...
About Astigmatism of the Human Eye Overview Astigmatism is a common eye condition, but severe forms can cause blurred vision. Astigmatism usually coexists with one or more other eye problems, such as myopia or hyperopia. It is easily diagnosed...
Cataracts, clouding of the lens that adjusts to help people see objects close up and far away, develop with age. Over half of all people 80 and older have cataracts or have had cataract surgery, according to 2009 data from the National Eye...
In order to understand what astigmatism is, and more specifically regular (versus irregular) astigmatism, let’s first get a basic understanding of what astigmatism is in general. The normal human eye has several structures that are...
Eye contact lenses were first developed in the 1960s, and have continually improved. The early contact lenses were known as hard contact lenses. That is, these lenses were rigid. They were made of a plastic called polymethyl methacrylate (PMMA)....
Contact lenses, or contacts, are thin pieces of rigid or flexible plastic that can be applied to the cornea of the eye. They can be used to serve a variety of purposes. They may be used correctively in the same way as glasses, therapeutically to...
Contact lenses help athletes see better because the lenses sit right on the eye and provide a more natural field of vision than glasses. But that's not the only reason to wear them for football. The American Academy of Ophthalmology notes that...
