Out of the many types of contact lenses on the market,
soft contacts are one of the most popular and widely-used varieties. Many
people prefer soft contact lenses thanks to their flexibility, which provides a
higher level of comfort than rigid gas permeable contacts. Soft contacts are
thin, gel-like lenses that fit comfortably in the eye and are virtually
invisible once inserted. The soft lens bends light according to your
prescription to correct refraction errors and clarify your vision.
Many soft contact lenses also provide built-in UV
protection. Shielding your eyes from harmful UV rays keeps them healthy and is
believed to slow the development of certain conditions such as eye
cataracts.
Types
of Soft Contact Lenses
Some types of soft contact lenses are designed for
daily or one-time use, while others are worn for extended periods of time. Each
type provides unique benefits which you can match to your lifestyle needs. If
you are unsure of what type of soft contact lens to wear, your certified eye
care specialist can help you make an informed decision.
Single-use
soft contact lenses. Single-use lenses are the most
expensive type of soft contact lens, but they are convenient for people
with active lifestyles. A new pair is inserted each morning and then
disposed of at the end of the day. Single-use soft contact lenses do not
require the use of any special solutions throughout the day, as they are
packaged with an adequate amount for the amount of time they’re intended
to be worn.
Daily
wear soft contact lenses. These soft contacts
are also disposable, but they are intended to be re-used daily for 1 to 4
weeks. Contacts designed for seven day use tend to be more flexible than
pairs designed to withstand the full 4 weeks. Daily use contacts are
inserted every morning and removed before going to sleep. Because proteins
and microorganisms can build up and cloud the lens, it’s important to
follow recommended cleaning guidelines. Daily wear lenses are less
expensive than single-use contacts, but they do require daily maintenance,
cleaning, and upkeep.
Extended
wear soft contact lenses. Extended wear contact
lenses can be kept in the eye for up to seven straight days without
removal, thanks to their ability to allow oxygen to the cornea, even during
sleep. Extended wear contacts have a controversial reputation, and some
eye care specialists question the safety of wearing corrective lenses for
prolonged periods of time. Although oxygen can pass to the retina, a
certain percentage does not pass through. Overnight wear is another
disputed habit, as some doctors argue it can increase the risk for corneal
disease and complications as microorganisms and other pollutants build up
on the lens.
Colored
soft contact lenses. Many colored contact lens
are used to change the natural color of your eye, while others are tinted
for a range of specific purposes. Visibility tint contacts do not change
the color of your eye, but make it easier to find a contact that is
accidentally dropped. For athletes, soft contacts with a light-filtering
tint make it easier to see by enhancing certain colors and muting others. Aesthetic
tints may completely change the color of your eye, or provide a subtle
tint that enhances and highlights your natural color.
During the initial eye examination, your eye
doctor will be able to recommend the appropriate type of contact lens for your
needs. Make sure to discuss any special lifestyle needs that you have which may
influence the decision. For example, if you’re active, busy, or forgetful, the
type of contact lens prescribed to you will be changed to suit your
circumstances. Take advantage of new lens technology to find an option that
fits your eyes and your daily life like a glove.
