Contact Lens Information

In years past contact lens wear was for the rich and patient. Lenses were expensive, very uncomfortable, did not correct vision sufficiently, and caused many eye infection problems. This is no longer the case. In fact many prefer contact lenses to eyeglasses, for price, comfort, and efficiency. Today contacts can correct all types of vision problems that glasses correct and some that glasses cannot. Unfortunately, due to their prior bad reputation, the full potential of contact wear has not yet been realized.

BENEFITS OF CONTACTS OVER SPECTACLES

  • Feeling good about yourself. Of course seeing is vital. But if you can see well and feel natural looking, all the better. It is no secret how important good self esteem is, contacts can be apart of that.
  • Relieve pressure on your face. The constant pressure on your nose, cheeks and ears is eliminated with contact lenses. You know the relief you feel when you take your glasses off every night, imagine that relief all day.
  • Convenience. Avoid the constant cleaning of glasses all day long. Put your contacts in and forget them. They are that comfortable.
  • Play sports without worry or embarrassment. Wearing regular glasses during sports leaves you with constant distraction of worrying that your glasses will break. Sports glasses are safe but bulky and leave you constantly self-conscience of your looks, distracting you from the game.

CONTACT LENSE TYPES

Contact lenses can be separated into two categories based on the material they are made of and the amount of oxygen they allow to flow through them (gas permeability).

  • RGP (Rigid Gas Permeable), commonly known as hard contacts, contain no water and are a little uncomfortable initially to the new wearer. However, they allow the greatest oxygen flow to the eye, which is important for proper eye function. RPG lenses can correct the most types of vision problems, last longer than other types of contact lenses, cause the least amount of problems and are easy to care for.
  • Soft Contact Lenses seem to be the more popular type of contact, primarily due to increase initial comfort to the new wearer. They have a high water content. There are three main sub-divisions to this category.
  • DAILY WEAR CONTACTS. Most people who wear contacts use these. They are inserted every morning and removed every night.
  • DISPOSABLE CONTACT LENSES. Disposable soft contact lenses cause the least amount of infections of this category of lens. They are generally worn for a specific period of time (most doctors recommend 7-14 days) and then discarded.
  • EXTENDED WEAR CONTACTS. These are worn from 7 – 30 days, day and night. They allow a greater oxygen flow, but can cause greater problems due to the extended wear.

WHAT ABOUT THESE EYE PROBLEMS?

There are two main eye problems contact lens wearers’ face, corneal infections and reduced tear production. The reduction of oxygen flow to the eye can result in corneal infections. However with advances in oxygen permeability these infections have decreased. The addition of a foreign object in your eye reduces its mobility, which in turn results in decrease tear production. As tearing cleanses the eye, this can lead to infection.

Proper lens and eye care as prescribed by your eye doctor can prevent most eye problems caused by contact lens wear. It is worth the perceived inconvenience, to gain all the benefits of wearing contact lens.
