Contact Lenses

Contact Lenses
Wearing contact lenses is one of the most popular ways of correcting a range of vision issues. Dr. Berke is well experienced with providing contacts for patients. Here are some of the most frequently asked questions we get here at Super Vision Center regarding the use of contacts among our patients.

Contact Lenses Q & A

Super Vision Center

What are Contact Lenses Made From?

Contact lenses are made out of several different types of plastics.  Soft contact lenses are made out of flexible gel-like hydrophilic (water loving) plastic.  There are also hydrophobic rigid gas permeable (RGP) lenses that allows oxygen to flow through the lens to the cornea.  There is a category of RGP contacts known as hyper oxygen permeable contacts.  These are used for corneal refractive therapy and Ortho-K for overnight vision correction.  They are so oxygen permeable (even more so than soft contacts) they allow the cornea to breathe when worn like it isn’t even there.  Ortho-K lenses are a revolutionary alternative to regular contacts that actually may stop the progression of Myopia and allow patients to see without irritation.

How Long Do Contacts Lenses Last?

Even with proper care, contact lenses must be replaced regularly to prevent deposits from building up and minimize the risk of contamination.  Soft lenses are available in different varieties, according to the duration of time they can be worn safely.  These include:

  • Disposable- these are discarded every 2-4 weeks.
  • Daily- these are discarded nightly and should only be worn once.

Rigid Gas Permeable lenses can last a lot longer because they are not as susceptible to deposit accumulation.  RGP lenses can last 1-3 years or occasionally longer.

What Eye Conditions are Treated Using Contacts?

While some contact lenses are worn cosmetically to change eye color, the vast majority of contacts fitted today are to correct refractive errors like myopia (near sighted), hyperopia (far sighted) and or astigmatism.  You can also use contacts for orthokeratology as a way to treat refractive errors overnight.  If you need to have bifocals or progressives you can also use contact lenses called multifocal CLs.  They offer an alternative for individuals suffering from age-related vision loss (presbyopia) and who prefer not to wear bifocals or trifocals or progressive lenses to be able to see clearly.  Other eye conditions treated using contacts include color vision deficiencies which can be improved in some patients with contacts.  Therapeutic scleral lenses are used to treat keratoconus and other corneal disorders including post surgical mishaps.
