These thin plastic discs correct, improve all types of defective vision.They are also used for bandaging the eye after surgery and for cosmetic purposes to change the colour of the eye. They come as Rigid and soft lenses with varying levels of oxygen permeability- the greater the permeability the better.

Types of contact lenses

Rigid Gas Permeable (RGP) : Lenses are semi-rigid lenses made usually from acrylate and fluorosilicone, a plastic which 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,& 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 colour of one’s eyes for fashion.

Irrespective of the type all lenses accumulate deposits from the secretions of the eye and the environment. All soft lenses are contaminated within 24 hours, when not in the eye, due to the water contained in the material. This makes contact lens care of vital importance.

Contaminated lens can cause

  • Recurrent infections
  • Red eyes
  • Papillae (pimples) on the inner lining of the upper eye lids
  • Reduced vision
  • Contact lens care
  • Lens should be kept clean, disinfected and hydrated
  • Hypoallergenic solutions formulate for sensitive eyes
  • Papillae (pimples) on the inner lining of the upper eye lids
  • Clean daily by rubbing in the palm of the hand with a surfactant cleaner
  • Protein cleaning should be done once a week

Frequent Replacement Lens

Build up of contaminants over a period of time, from three months onwards, is inevitable. A new system called Frequent Replacement has been introduced. Lenses are replaced on a Daily, Weekly, Monthly or Quarterly (once in three months) basis. Frequent infections are eliminated and the eye gets more oxygen. Vision and comfort are greatly enhanced and simple cleaning systems like multipurpose solutions can be used.
