Eye health : about healthy contact lens

Today just about everyone can wear contact lenses, and there are more healthful and convenient contact lens options than ever before. It has been estimated that about 125 million people use contact lenses worldwide (2%), including 28 to 38 million in the United States and 13 million in Japan. The types of lenses used and prescribed vary markedly between countries, with rigid lenses accounting for over 20% of currently-prescribed lenses in Japan, Netherlands and Germany but less than 5% in Scandinavia.

A contact lens is a corrective, cosmetic, or therapeutic lens usually placed on the cornea of the eye. Contact lenses usually serve the same corrective purpose as conventional glasses, but are lightweight and virtually invisible. Cosmetic lenses are deliberately colored for altering the appearance of the eye.

Types of Contact Lenses:

  1. Bifocal Contact Lenses : provide both near and distance vision
  2. Colored Contact Lenses : give your eyes a subtle or dramatic change
  3. Disposable Contact Lenses : enable a healthier wearing experience
  4. Monovision : an alternative to bifocals for presbyopia
  5. Orthokeratology Lenses : for overnight corneal reshaping
  6. Prosthetic Contact Lenses : mask eye injury or disfigurements
  7. Silicone Hydrogel Contacts : transmit more oxygen to your eyes
  8. Special-Effect Contact Lenses : let you become a leopard or cheetah
  9. Specialty Lenses : for the "hard-to-fit" patient
  10. Toric Contact Lenses : provide good vision if you have astigmatism

Proclear contact lenses

Proclear contact lenses let you enjoy an unrivaled level of comfort all day long. It’s an exceptional level of comfort made possible by PC Technology, which creates a unique material containing molecules of phosphorylcholine (PC), a substance found naturally in human cell membranes. These molecules attract and surround themselves with water, keeping Proclear lenses moist and comfortable, even after 12 hours of wear.

Proclear Compatibles offer distinct advantages because they are the only contact lenses made with PC:

  1. PC enables Proclear Compatibles to be more readily accepted by your eyes
  2. Materials made with PC have a high affinity for water. Proclear Compatibles are very resistant to dehydration, so they stay moist and comfortable on your eyes.
  3. PC materials have a permanent water layer on the surface, which acts as a barrier to protein and lipid adhesion. Proclear Compatibles resist deposits that can cause discomfort and block the flow of oxygen through the lens.
