Family Vision Source in Tucson offers many options for contact lenses.
There are a number of reasons why you might prefer contact lenses to standard eyewear: a glasses-free look, hassle-free vision correction, wearing non-prescription sunwear and goggles, or the convenience of not having to worry about misplacing your glasses. If you have a high prescription or astigmatism, contact lenses may provide more enhanced vision correction than glasses. Today, you can even replace your bifocal glasses with bifocal contact lenses.
Your eye care provider can recommend the best contact lenses for you based on a complete eye examination and a review of your visual needs both at work and play. Since most people can wear more than one type of lens, it’s important to know what the choices are and the advantages and disadvantages to each.
“Why is my contact lens prescription different from my eyeglasses prescription?”
A contact lens prescription is for the purchase of contact lenses only. This prescription is determined through additional testing by the doctor including exact measurements of shape, slope and contour of your corneas. The exact power of the prescription may vary from your eyeglasses prescription since a contact lens sits directly on your eye.
“Can I wear contacts if I have astigmatism?”
This once-true statement is now a myth. If you have astigmatism – a common condition where the eye isn’t perfectly round but more football- or egg-shaped – then you’ll need a special design of contact lenses called “toric” lenses for clear vision.
Toric contact lenses are available in both soft and rigid gas permeable (RGP or GP) lens materials. Most contact lens wearers who need toric contacts choose soft toric lenses.
These lenses are comfortable to wear and must be replaced monthly, bi-weekly, or daily depending on the type prescribed to you. Soft lenses are often recommended for sports because they fit closer to the eye and are more difficult to dislodge. They can provide correction for most prescriptions including astigmatism.
Gas-Permeable (GP) Lenses
Made of moderately flexible plastics, GP lenses offer sharp vision and correct most vision problems. Like hydrogels used for soft lenses, materials used to create GP contact lenses also are “gas permeable,” allowing oxygen to pass through the lenses to the cornea. They are more durable than soft contact lenses and can be easier to handle and care for, but require a longer adaptation period and consistent wear to maintain adaptation.
In both soft and gas-permeable designs, multifocal lenses offer patients both distance and near vision correction. Bifocal contacts lenses have two prescriptions in the same lens. Multifocal contact lenses have a range of powers (similar to progressive eyeglass lenses) in each lens.
The term, ‘multifocal contacts’ is used as a catch-all term for all contact lenses with more than one power, including bifocal contacts.
How Multifocal Contact Lenses Work:
Bifocal and multifocal contact lenses work in several different ways, depending on the design of the lens. The designs fall into two basic groups:
- Alternating vision (translating) lenses are so named because your pupil alternates between the two powers, as your gaze shifts upward or downward.
- Simultaneous vision lenses require your eye to be looking through both distance and near powers at the same time. Although this might sound unworkable, your visual system learns to select the correct power choice depending on how close or far you’re trying to see.
Color Contact Lenses
Enhance your eye color or even change it completely. Colored contact lenses are fun and come in a variety of colors for both light and dark eyes.
There are 3 types of tint available for colored contact lenses:
- Visibility Tint – This is typically a light color tint present on the lens for the sole purpose of ease of use – seeing the lens itself during insertion and removal or if the lens is dropped. These do not enhance your eye color, and are function only.
- Enhancement Tint – The tint on enhancement lenses is darker and intended to augment your current lens color. If you have lighter eyes to begin with and are looking for a small adjustment in lens color these are the lenses for you.
- Opaque Tint – These colored contact lenses can drastically change the color of your iris. If you have a naturally dark eye color such as hazel or brown you may require an opaque tint to see a true difference in your eye color.
Synergeyes contact lenses combine the superior vision of a gas permeable lens with the comfort and ease of wear of a soft contact lens.
