Contact Lenses- Doyelstown

Bifocal/Multifocal lenses

These lenses provide clear vision for those who have trouble seeing at more than one distance. Bifocals can improve both close vision, as for reading, and distance vision, as for driving. Multifocals also provide clarity in the middle range, such as is necessary for doing computer work.

Monovision Lenses

Monovision lenses are an ingenious way to correct both nearsightedness and farsightedness in patients for whom bifocal lenses are not comfortable. With this solution, the lens in one eye corrects your near vision and the lens in the other eye corrects your distance vision. These lenses are not for everyone, however. While the majority of patients adapt to the monovision lenses, approximately 20 percent do not.

Rigid Gas Permeable Lenses

Rigid gas permeable (GP) lenses are rigid lenses quite different from the old-fashioned hard contact lens, now obsolete. GP lenses, made of durable plastic that transmits oxygen, are more flexible than their predecessors and also allow oxygen to permeate. These attributes provide advantages to the patient, both in terms of comfort and in terms of eye health.

GP lenses are useful for many eye conditions, including:

• Astigmatism
• Presbyopia
• Keratoconus

Both astigmatism, a very common condition, and keratoconus, a rare hereditary ailment, are caused by a misshapen cornea. Because the harder GP lenses exert some pressure on the cornea, they are helpful in correcting the problem. GP lenses come in various bifocal and multifocal designs. They are especially useful for patients who require extremely precise vision and for those who want their contact lenses to last for a long time.
