Colored Contact Lenses: What Are the Different Classes of Contact Lenses?

Contact lenses, or just contact lenses, are small translucent lenses usually placed directly upon the cornea of the eye. Contact lenses have been used for over 15 years in the treatment of vision problems, including to correct nearsightedness and farsightedness and also to improve eyesight when the patient has had no other treatments of its kind or before beginning a lens regimen. Currently, approximately 150 million people around the world have the use of contact lenses to address their vision needs. To this day, more people continue to use contact lenses than ever before for one reason or another.


Reduce the development of cataracts and other eye problems

One of the primary reasons that people choose soft contact lenses is the fact that soft contacts allow for more oxygen flow within the eye. The oxygen that is allowed to flow freely within the eye is important because it helps to sustain the health of the eye and can even help to reduce the development of cataracts and other eye problems. Additionally, the oxygen that is permitted to enter the eye must be able to stay within the eye for the duration of the wearing time.


Soft contact lens

There are several different types of soft contact lenses, but in most instances, your optometrist will be able to provide you with an accurate answer as to which type of contact lens you are currently requesting. If you are currently wearing glasses, then you are likely going to be a candidate for a soft contact lens. If you currently wear glasses only because of a vision deficiency such as nearsightedness, then soft lenses may not be necessary for your situation. If you wear glasses for your entire eyesight needs, then you may be a good candidate for a bifocal contact.


Scheduling your initial consultation

Typically, all patients who want to change their eye colors or other features of their vision will be advised to see an eye doctor so that the appropriate contact lenses can be provided for them. When scheduling your initial consultation with your eye doctor, you will be asked questions about your current eye care and any past issues you may have had with your vision. These questions will also allow your eye doctor to make a better assessment of how your current vision condition is affecting your ability to retain peripheral vision and to make appropriate contacts for your specific situation. This information will ultimately help your optometrist to determine how much contact lenses should be recommended for you based on your current vision condition.


Different levels of strength of lenses and function differently in the eye.

There are three primary classes of contact lenses available from your optometrist. All of these categories have different levels of strength of lenses and function differently in the eye. They include Standard, intermediate, and superior contact lenses. The classification of your prescription will determine the strength of the contact lenses you are requested to use. Generally, stronger, higher power lenses require that you use fewer, less powerful prescriptions to cover the area that you need to be covered.


The classification of your prescription will also determine the level of correction that will be needed for your eyes. Typically, a patient who is in the Standard Strength category will not require as much correction to their eyes as someone who is in the Intermediate or Superior group. Your eye doctor is the best-qualified individual to determine what level of correction is most appropriate for your particular situation so that you can get the most benefit and minimize the wear on your contact lenses. Always discuss this issue thoroughly with your eye doctor before beginning the contact lenses regimen.
