Many lens designs are available to correct various types of vision problems:

  • Spherical contact lenses are the typical, rounded design of contact lenses, which can correct myopia (nearsightedness) or hyperopia (farsightedness).
  • Bifocal contact lenses contain different zones for near and far vision to correct presbyopia.
  • Orthokeratology lenses are specially designed to reshape the cornea during sleep, providing lens-free daytime wear.
  • Toric contact lenses correct for astigmatism, as well as for myopia and hyperopia.

All of these lenses can be custom made for hard-to-fit eyes. Many other additional lens designs are available. Typically these are less common and fabricated for use in special situations, such as correcting for keratoconus.

Contact Lens Features

Colored Lenses. Many of the types of lenses described above also come in colors that can enhance the natural color of your eyes — that is, make your green eyes even greener, for example. Or these lenses can totally change the eye's appearance, as in from brown to blue.

Special-Effect Lenses. Also called theatrical, novelty, or costume lenses, these take coloration one step further to make you look like a cat, a zombie, or another alter-ego of your choice.

Prosthetic Lenses. Colored contact lenses can also be used for more medically oriented purposes. People with disfigured eyes, as a result of accidents or disease, can use a custom, opaque colored lens to ma

sk the disfigurement and match the appearance of their normal eye.

Custom Lenses. If conventional contact lenses don't seem to work for you, you might be a candidate for a customized design.

UV-Inhibiting Lenses. Today, many contacts incorporate an ultraviolet blocker in the lens material, to cut down on UV light that can eventually cause cataracts and other eye problems. You can't see this blocker by looking at the lens. And since contacts don't cover your entire eye, UV blockers cannot substitute for traditional sun protection like good quality sunglasses.

Hybrid Lenses. One brand of lenses features a GP center with a soft outer skirt, providing wearers with both the crisp optics of a rigid lens and the comfort of a larger, soft lens.

Which Contact Lens Is Right for You?

First, your contacts must address the problem that is prompting you to wear lenses in the first place. Your contact lenses must provide good vision by correcting your myopia, hyperopia, astigmatism, or some combination of those vision problems.

Second, the lens must fit your eye. To do that, lenses come in tens of thousands of combinations of diameter and curvature. Of course, not every lens brand comes in every "size."

At Dr. Albert Ng and Associates, wehave skilled professionals in evaluating your eye's physiology, and your eyesight, to determine which lens best satisfies the two criteria above.

Third, you may have another medical need that drives the choice of lens. For example, your ECP might pick a particular lens if your eyes tend to be dry.

Finally, consider your "wish list" of contact lens features — colors, for example, or overnight wear.

When we decide on the right lens for you, you'll be given a contact lens prescription. You'll be able to buy a supply of lenses from your ECP or from the many other outlets that sell contact lenses.
