Contact Lens
Contact Lenses are simple to wear and care for, and are almost undetectable. They are thin discs of plastic, curved on the inside to fit properly onto the surface of the eye, and shaped on the outside to correct and improve defective vision, for bandaging the eye after surgery, and cosmetic benefits, e.g., to cover white scarring of the eye or to change the color of the eye for fashion. With advancing technology, Contact Lenses can correct all forms of visual defects including Astigmatism safely and comfortably. There are basically two types of contact lenses: Rigid and Soft. Both types come in varying materials with different levels of oxygen permeability. The higher, the oxygen permeability, the better it is for the eye.
With major advances in materials, millions of people have discovered that contact lenses are a safe, comfortable, convenient and affordable alternative to spectacles. Contact lenses are thin, domed discs made of complex plastic materials, and are positioned in front of the transparent outer layer of the eye called the cornea, to focus images onto the retina at the back of the eye. There are basically two types of lenses:
Rigid Gas Permeable (RGP)
RGP lenses are semi-rigid lenses made usually from acrylate and fluorosilicon, a plastic that allow oxygen through to the eye. They are clinically the best as they allow maximum oxygen to reach the cornea being smaller in size. They are easy to care for, durable and give good clarity of vision. They can be prescribed for all types of vision correction, including high astigmatism, bifocals, post surgery (RK, PRK and Lasik), therapeutic, and cosmetic for all age groups. In certain cases, these lenses are also prescribed for myopia control.
Soft lenses
Soft lenses are made from water-absorbing plastics, which make them pliable and membrane-like for maximum comfort. They are ideal for sports as they cannot be easily dislodged from the eye.
New silicon based soft lenses allow maximum oxygen to the cornea, enabling overnight continuous wear safely for a month. With modern manufacturing techniques, soft lenses can be made to correct all types of refractive errors and many types of lifestyles. Soft lenses are available in toric (to correct astigmatism), bifocal, weekly disposable, monthly disposable, daily disposable, extended wear and cosmetic to cover corneal scars, as well as to change the color of one's eyes for fashion.

Contaminated contact lenses are very dangerous and a serious threat to the eye. Careless handling can be sight-threatening. A good Contact Lens Specialist will spend time to properly educate the patient regarding the cleaning and disinfection of their lenses and have, at their disposal, proper instruments for fitting and supply of contact lenses. It is this combination of good advice and services that make it possible to adapt to contact lenses successfully and safely. Always take advice from a properly qualified Contact Lens Specialist to tell you, which lenses are suitable for your eyes after examining them thoroughly.
