Choosing The Right Contact Lenses
You want to wear contact lenses. You've probably heard a lot about the different
types available today. You may even think you know what type of lens you want.
But have you considered all your options?
With today's technology, most people can wear contact lenses successfully. But
no one can wear all types and designs. Your optometrist will recommend what will
work for you based on your general health, eye health, vision and occupational
needs and lifestyle. But, if you're like most people, you'll still have choices.
Safe, comfortable, successful wear depends upon your making an intelligent decision
together with your optometrist. So take time to review your contact lens options.
Look at the types of lenses
Let's begin by looking at what's available.
SOFT
LENSES
- Made of many different flexible water absorbing plastics that allow oxygen to
pass through them to nourish the eye;
- Offer easy adaptation;
- comfortable wear
almost from the start;
- ability to switch from contacts to glasses without experiencing
any blurred vision;
- on and off wear without readaptation;
- close fit, making them
less likely to dislodge or get dirt trapped under them.
But soft lenses don't correct all vision problems, may not provide the sharp
vision some other lens types do and need replacement periodically as recommended
by the optometrist. Still, they are the most popular contact lenses worn today.

RIGID GAS PERMERABLE (RGP) LENSES
- Made of
different rigid or slightly flexible plastics that allow oxygen to pass through
them;
- Offer sharp, crisp vision;
- ability to switch from contacts to glasses without
experiencing blurred vision;
- correction for most vision problems;
- durability,
with less frequent replacement than soft lenses;
- require a longer adaptation period and consistent wear to maintain adaptation
- Can be dislodged during active
sports participation.
- RGP lenses are growing in popularity.

STANDARD HARD LENSES
- Made of tough inflexible plastic that does not permit oxygen
to pass through them;
- With proper fit, oxygen goes around and under lens;
- Offers sharp vision;
- Greatest versatility in correcting vision problems;
- Most durability, lasting several years. But require longest adaptation period and almost
daily wear to maintain adaptation;
- May cause temporary blurred vision when switching
to glasses
- Can slip off the eyes and create cornea1 abrasions if worn too long;
- The oldest type of contact lenses, standard hard lenses are rarely prescribed today.

|
EXTENDED WEAR LENSES
- Many are soft lenses made of high water content
plastics but RGP versions are also available
- Government approved for continuous
wear for up to 30 days (soft lenses) or one week (RGP lenses) but eye health protection
demands removal for cleaning and a night's rest every week;
- Require three or four
office visits a year for follow-up care and frequent replacement;
- Extended wear is rarely prescribed due to increased risks of eye infection and injury.

SPECIAL DESIGNS
Include toric soft lenses for high degrees of astigmatism;
bifocals, available in daily wear lenses only; silicone lenses; and combination
RGP/soft lenses.
TINTED LENSES
Available in soft, RGP, and extended wear lenses,
some are light identification tints but many daily and extended wear soft lenses
are darker to enhance eye color and others have clear centers surrounded by deep
tints that change eye color.

Finding what's right for you
Several factors go into determining which type of contact
lens is right for you.
Your eyes. Your vision problem,
lens prescription and eye health needs may limit your lens choices. Using the
results of a thorough eye examination and contact lens evaluation, your doctor
of optometry will advise you on these matters.
Your lifestyle. Gear your lenses to your activities.
If you are athletic, consider soft lenses. Need the sharpest vision possible on
the job? Try RGP lenses. Like camping? Travel a lot? Daily replacement lenses
may be for you. Seek your optometrist's advice.
Your personality. Impatient? Soft lenses have the shortest
adaptation. Cost conscious? RGP lenses need less frequent replacement. Fashion
oriented? Consider deep tinted soft lenses. Talk it over with Dr. Reeves.
Cost. Don't base your decision on cost alone. You want
the lens that is healthiest for your eyes and provides the best vision. Be wary
of bargain prices. Be sure the price quoted covers a thorough diagnostic examination,
the lenses, lens care kit, training on proper lens wearing and care procedures
and unlimited scheduled follow-up visits over a specified time. Thorough care
will pay off in years of safe and successful wear.
Don't forget...
Your doctor of optometry is a skilled, concerned professional
who offers a wide variety of types and brands of lenses, stresses long-term management
care and is willing to discuss the contact lens options open to you. Together,
you can determine just what contact lens is the best for you.
