Contact Lens Types

TYPES OF CONTACT LENSES


  • SILICONE HYDROGEL:   Success with contact lenses requires that the eye stays healthy under the lens. To no small measure, the amount of oxygen that moves through the lens can determine whether the lenses are worn succcessfully. The new silicone based materials pass 4-6 times more oxygen through them than previous lens materials, improving lens tolerance significantly.
  • ASTIGMATIC LENSES:   Astigmatism means the shape of the eye is more like a football than a soccer ball. Astigmatic lenses are made to compensate for this irregular shape. They do this by matching the irregular shape of the cornea in the opposite direction. As you might expect, alignment of the contact lens is very important with any rotation resulting in blur. Newer lenses maintain this alignment better than ever before. Coupled with the new materials, these astigmatic lenses provide more consistant vision for longer hours of wear.
  • BIFOCAL LENSES:  Bifocal correction in contact lenses is the most difficult of all contact lens corrections. That said, the newest lenses from Bausch & Lomb, as well as, Johnson & Johnson, do a respectable job of providing bifocal correction. They work especially well in patients in their early to mid 40’s.
  • ONE DAY DISPOSABLE LENSES:  This has become our favorite contact lens modality. It is the ultimate in contact lens convenience and safety. Dirty, overworn contact lenses are a major source of irritation and infection in our patients. In addition, contact lens solution intolerance can contribute to eye irritation. One day disposable lenses solve many of the common eye problems we see associated with contact lens wear. While these lenses cost a bit more, there are significant rebates available to help transition into these lenses.
