About 125 million people around the world wear contact lenses as an alternative to glasses for the correction of refractive errors (spectacle numbers). Crystal Optical offers you various contact lenses options including Soft contact lenses (including disposable), Toric contact lenses, Cosmetic contact lenses, Rigid Gas-permeable (semi-soft) contact lenses.
What Are Contact Lenses?
Contact Lenses (CL) are small, thin, curved transparent discs that are designed to rest on the cornea, the clear front surface of the eye. Contacts cling to the film of tears over the cornea because of surface tension, the same force that causes a drop of water to cling to the side of a glass. Contact lenses are mostly used to correct near-sightedness, far-sightedness and astigmatism. Contacts provide a safe and effective way to correct vision when used with care and proper supervision. They can offer a good alternative to eyeglasses, depending on your eyes and your lifestyle. However, one must remember, they are health devices, not commodities or beauty aids, and not everyone can wear them. Also, their use can affect the well-being of your eyes and only an optometrist or an ophthalmologist (eye surgeon) is qualified to assess the health of your eye. Your healthy vision is the first priority.

There are basically two types of contact lenses:
1.Rigid Gas-permeable (RGP) Contact Lenses which are also known as “semi-soft lenses”

The cardinal aspect in contact lens dispensing is not the sale. It is the care of the lens by the wearer that is the critical factor. We give great emphasis on educating the patient on using the contact lens as well as the cleaning and storage of the lens.
