Contact Lens Clinic

As the use of contact lenses has grown exponentially in recent years, so has the demand for contact lenses that can enhance vision without the need for eyeglasses. The most common types of contact lenses include soft lenses and rigid gas permeable lenses. Contact lenses have become increasingly popular as people have sought to correct their vision without the need for eyeglasses or other types of corrective lenses. Contact lens enhance the vision of the wearer by reducing spectacle aberrations and increasing the visual field, thus giving a natural vision.

Contact Lens Materials

Contacts are made up of different types of materials. When considering contact lenses, you need to select material that will best satisfy your needs. According to material used, there are five types of contact lenses -

  • Soft lenses - made from hydrogels - gel-like water-containing plastic. Soft lenses are very thin and pliable.

  • Silicone hydrogel lenses - these are advanced version of soft contact lens material. Silicon hydrogel lenses allows more oxygen to pass through the lens. Silicone hydrogel contact lenses are most popular type of contact lenses.

  • Gas permeable lenses (GP or RGP lenses) - rigid contact lenses that maintain their shape on the eye, enabling them to correct astigmatism and other refractive errors. Gas permeable contact lenses typically are smaller in diameter than soft lenses and are made of highly oxygen-permeable materials. It usually takes some time for your eyes to adjust to GP lenses when you first start wearing them; but after this initial adaptation period, most people find GP lenses are as comfortable as soft lenses.

  • Hybrid contact lenses - have a rigid gas permeable central zone, surrounded by a "skirt" of hydrogel or silicone hydrogel material. They are designed to provide wearing comfort that rivals soft or silicone hydrogel lenses, combined with the crystal-clear optics of GP lenses.

  • PMMA lenses - rigid contact lenses that look like GP lenses but are made of a plastic material that is not oxygen permeable. PMMA lenses were commonly prescribed years ago, but essentially have been replaced by gas permeable lenses.
