Contacts & Solutions

Contact lenses are small plastic water permeable membranes worn on the surface of the eye over the cornea primarily to correct vision. There are also lenses worn primarily for cosmetic purposes.

Contact Lenses are frequently improved with the latest advancements in technology to provide the best comfort and quality vision. Contact lenses, when used properly, are very convenient and are extremely comfortable. After the normal adaptation period you will hardly know you are wearing them, but you will certainly notice how clear and your vision is without your glasses.

We recommend always having a backup pair of eye glasses in conjunction with your contact lenses. This allows you to best meet your overall lifestyle needs while protecting the integrity of your overall eye health. Even though contact lenses are a cosmetic convenience they are not suitable for every situation, such as dusty environments, ocular irritation, recent eye infections, and etc.

Many patients choose contact lenses for their cosmetic benefits, as well as the capability of performing certain activities and events where they would rather not wear their glasses. Even though many patients choose contact lenses for the primary reason of getting out of their glasses all patients should have glasses as a backup option.

Contact Lens Types

The types and variety of contact lenses available have expanded greatly in the past few years. There are lenses available for almost everyone. Many of our patients were told in the past that they could not wear contacts, or they tried and were unsuccessful. You owe it to yourself to see what is new. We carry many options, and promise to do our best in selecting contact lenses that you will love wearing. Choose from the following list for a brief look at some of the options available to you.

Conventional Soft Lenses

Soft lenses are comfortable and come in a variety of types, depending on the wearer’s needs. Conventional soft lenses are designed to be worn during the day, cleaned, and stored at night. Usually once a week the lenses must receive an additionalcleaning using an enzymatic cleaner, which removes protein deposits. These lenses can last for upto a year if your prescription stays the same and you take good care of them. As technology improves, this older type of contact lens is being replaced by frequent replacement and disposable soft contact lens. Special customized contact lenses fall into this category.

Disposable Soft Lenses

Disposable soft lenses are much more popular than conventional soft lenses. These lenses are worn for a period of time and then, of course, thrown away. The most well-known disposables last for two weeks or one month but that is quickly changing to the one-day disposables These are perfect for many patients who were told they could not wear contact lenses because of allergies or mild dry eye conditions. They have a low cost per lens, are extremely convenient and reduce the risk of contact lens related eye infections making them ideal for teenagers, college students and any busy adult. They are also popular for athletes and hobbyists who do not necessarily want to wear contact lenses every day.

Tinted Soft Lenses

Next, you have tinted soft lenses, available in conventional, disposable, or frequent replacement types. With tinted soft lenses, you can change your eye color or enhance your eye color. Even if you don't need corrective lenses, you can use "plano" tinted lenses to change your eye color.

Multifocal Soft Lenses

Recent technology has greatly improved the bifocal soft contact lens to a new and improved multifocal lens. These contact lenses function similar to progressive or no-line bifocals by providing multiple ranges instead of just two distances. Now, patients past their 40s who need bifocals can enjoy the comfort and benefits of soft contact lenses.

Toric Soft Lenses

Toric lenses are used to optically correct astigmatism. Astigmatism is a vision condition where a non-uniformed shaped cornea affects the vision. In the past, the only options for those with astigmatism were either glasses or hard gas permeable contact lenses. But toric soft contact lenses, which are lenses with a special design, now offer a fantasticalternative. There are several types of toric lenses to choose from–with a design to suit most visual requirements including disposables.

Extended Wear Soft Lenses

Extended wear lenses, the result of advanced technology in lens materials, transmit more oxygen to the cornea of the eye. Some of these lens materials are approved for up to 30 days of continuous wear. Extended wear lenses can last one week, two weeks, or one month, depending upon the lens material and your doctor’s recommendations.

Rigid Gas Permeable (RGP) Lenses

As the name implies, these lenses are hard and gas permeable. If you’ve been told you cannot wear soft lenses, RGP lenses are often a great alternative. RGP lenses are available in specialized designs to correct just about any vision disorder. RGP contacts are also very useful in managing eyes or prescriptions that are uncommon after such as after eye injuries, surgeries, Keratoconnus, etc.

Solutions

There are a variety of solutions available from many different manufacturers. The important thing to remember is that not every solution is right for every type of contact lens. Some contact lenses require the use of multipurpose solutions, while others require separate solutions for the four steps in contact lens care: disinfecting, cleaning, rinsing, and enzyming. Use only the lens solutions that are recommended by your eye doctor. If you wish to change brands, check with our office first.

Ocular complications and/or long-term corneal damage are the consequences of contact lenses that are worn longer than recommended. Oftentimes, your lenses will still feel good even when you are over-wearing them. Do not wear your lenses overnight unless they are approved for extended wear and your doctor has discussed this with you. Overnight wear increases the risk of infection and other complications.

Caring For Your Contacts

Deposits and infectious organisms such as bacteria, viruses--etc., can build up on the surface of all contact lenses. For this reason, it is very important to keep them clean and disinfected. The best way to care for your lenses is to follow the advice of the optometrist on how the take care of them!

There are Five steps in contact lens care—follow the care prescribed for your lenses:

  1. Cleaning removes dirt, mucous, and other debris that gets on the lenses during wear.
  2. Disinfecting kills bacteria (germs) on the lenses. Disinfecting is essential to prevent serious eye infections.
  3. Rinsing removes the other solutions from the lenses and prepares the lenses for wear.
  4. Enzyming uses enzyme drops or tablets to remove protein and other deposits that build up over time on the lenses.
  5. Replacing your lenses as directed. You can’t keep a worn out lens comfortable and safe by trying to clean it beyond when it is recommended to be replaced.

The best way to properly care for your lenses is to develop a care routine, then stick to it.  Remember to:

  • Follow the directions outlined by your eye doctor. Oftentimes instructions are also listed on the packaging or the package insert for the contact lens solutions prescribed for you.
  • Multi-purpose solutions can be used for more than one step in contact lens care. Read the label to see which functions the solutions can be used for.
  • Many solutions can not be used together, and not all solutions are appropriate for all types of lenses. Only use solutions recommended by your eye doctor, and check with your eye doctor if you want to switch brands.
  • When you remove your lenses, they must be cleaned, rinsed, and disinfected before they are worn again.
  • Enzyming and cleaning are not a substitute for disinfecting.
  • Lenses that have been stored for more than 24 hours should be cleaned, disinfected, and rinsed again prior to wear
  • Make sure solution containers are kept closed tightly, stored upright, and kept in a clean, dry, cool place when you are not using them. Keep your case clean and replace it every 3 months to prevent bacterial growth. In addition, cleaning the case with warm soapy water once a week, rinsing, and allowing it to air dry helps prevent bacterial buildup.
  • Don’t touch container bottle tips to any surface to prevent them from becoming contaminated.
  • Throw away expired solutions. (Look on the bottle for the expiration date!) A single contact lens wearer who wears contacts most days should be using about 8 bottles (12 fl oz) a year of multiple purpose solution to clean and store soft contacts. If you using substantially less than this, you are probably not adequately cleaning your contact lenses.
  • Use new solution in your contact lenses case every day sufficient to fully submerge the contact lenses in its case.
  • Discuss with your eye doctor the care for your lenses if you wear them while swimming in a pool, lake, or hot tub.
  • Only use approved rewetting drops for lubricating or wetting your lenses. Never place the lenses in your mouth. (Yuck!)
  • Do not use tap water to rinse soft contact lenses.
  • Be careful with makeup, lotions, creams and sprays--consider putting on lenses before makeup and remove them before removing makeup. Also, water-based makeup is less likely to damage lenses than oil-based makeup.

Here’s what you need to watch for: Redness, blurriness, light sensitivity. Remove your lenses if you are experiencing any of these 3 things. If severe symptoms are present, contact our office immediately. Otherwise, if your eyes have not returned to normal after 24 hours, please contact our office. If you have any change in vision, comfort, or irritation, immediately remove your lenses. If there is no improvement within a couple of hours, please contact our office.
