Contact lenses act as the first surface incoming light rays hit when entering the eye.

They work to correct ones vision by properly focusing incoming light onto the retina, thus producing clear vision. Others may use contact lenses for aesthetic purposes. For instance, actors and actresses may wear contact lenses to change the colour of the eyes for a particular role, or you might decide to see how you look with a new eye color. Cosmetic contact lenses are becoming increasingly popular. Taking care of your contact lenses is quite simple.

Wouldn't it be great if you could correct your eyesight and reduce your dependence on glasses or contact lenses — without having to undergo eye surgery? It might sound far-fetched, but it's a reality for many people. It's called orthokeratology, or ortho-k. Orthokeratology ortho-k is the fitting of specially designed gas permeable contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye cornea so you can see clearly the following day after you remove the lenses when you wake up. Ortho-k lenses are also called "corneal reshaping contact lenses" or "overnight contact lenses to correct or control myopia. But ortho-k can be safely and successfully performed with other gas permeable GP lenses and corneal reshaping fitting techniques. Only highly "breathable" GP lenses that have been FDA approved for overnight wear should be used for orthokeratology. Paragon CRT Paragon Vision Sciences is a specific brand of corneal reshaping lenses that has a proprietary lens design and fitting methodology, called corneal refractive therapy CRT.

Contact Lenses at Work

Many patients with vision problems heartily embrace the idea of enjoying vision correction without having to wear eyeglasses or contact lenses. Not all of these patients, however, are good candidates for PRK or Lasik surgery, the two standard surgeries used to alter the way the cornea of the eye refracts light. To understand the benefits of Ortho-K, let us first consider how the cornea works. The cornea is a transparent, spherical bulge that sits over the lens of your eye.

Handbook of Visual Optics offers an authoritative overview of encyclopedic knowledge in the field of physiological optics. It builds from fundamental concepts to the science and technology of instruments and practical procedures of vision correction, integrating expert knowledge from physics, medicine, biology, psychology, and engineering. The chapters comprehensively cover all aspects of modern study and practice, from optical principles and optics of the eye and retina to novel ophthalmic tools for imaging and visual testing, devices and techniques for visual correction, and the relationship between ocular optics and visual perception.

Vision Correction

The need for some type of vision correction is very common. Common vision defects are easy to understand, and some are simple to correct. Nearsightedness , or myopia , is the inability to see distant objects clearly while close objects are clear. The eye overconverges the nearly parallel rays from a distant object, and the rays cross in front of the retina. More divergent rays from a close object are converged on the retina for a clear image. The distance to the farthest object that can be seen clearly is called the far point of the eye normally infinity. Farsightedness , or hyperopia , is the inability to see close objects clearly while distant objects may be clear.

Corrective Lenses

Refractive errors can be corrected with glass or plastic lenses mounted in a frame eyeglasses or with a small lens made of plastic floating or resting on the cornea contact lens. Good vision correction is possible with both eyeglasses and contact lenses. For most people, the choice is a matter of appearance, convenience, cost, risk, and comfort. Aids for coping with vision loss referred to as low-vision aids can be an enormous help to people with only partial vision. Low-vision aids for reading, writing, watching television, and engaging in outdoor activities include the following:. Eye doctors working with other health care practitioners can usually evaluate how vision loss affects a person.

Thanks to the existence of contact lenses, it can sometimes be impossible to tell if someone has a visual impairment or not. These lenses can make huge differences to the lives of their wearers, providing a certain level of freedom that traditional glasses are unable to. While they might feel like a relatively modern invention, rigid contact lenses made from plastic were first manufactured in the US between and

Blurred vision can be a result of many things, such as a refractive error, but regardless of the reason it needs to be corrected.

A corrective lens is a lens typically worn in front of the eye to improve vision. The most common use is to treat refractive errors : myopia , hypermetropia , astigmatism , and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye.
