The optometry field’s continuous research and advances in technology have made it possible to create various types of contact lenses. Each one has their own distinct features and functions to improve your eyesight. For your understanding, let Guilford Eye Center discuss some of them in detail.
Hard Lenses
When contact lenses were developed in the late 1800’s, they were made of a hard material known as polymethyl methacrylate (PMMA). While they provided sharp optics, they did not allow oxygen to enter the eyes, putting users at a higher risk of developing contact lens-related complications. Fortunately, soft lenses were introduced in the early 1970s. Today, some variations are even gas-permeable for your improved visual comfort.
Dailies
Also referred to as daily disposables or “dailies”, this type of contact lenses is meant to be used for a single time only. Ideally, you’ll insert the soft lenses in the morning, then remove and discard them at night. This method is an effective way to reduce your risk of having infections and are by far the most comfortable lenses on the market today.
Disposables
Disposable lenses are designed to be used anywhere from 1-4 weeks. Rest assured your trusted eye care center will provide detailed instructions on their proper care and handling for your optimum visual health and protection. That said, we may advise replacing them sooner, depending on your personal circumstances.
Extended Wear
Extended wear contact lenses first came out in 1979. They are uniquely designed for overnight wearing while you go to sleep. Some may be left in your eyes for as long as thirty consecutive days without removing them.
Scleral or Specialty
There are certain eye conditions which may not be corrected by using regular contact lenses, like keratoconus. In such cases, we may recommend using specialty contact lenses or scleral contact lenses. They have a larger diameter, allowing them to cover most of your eyes’ surface for your better visual clarity and stability.
Multifocals
These contact lenses hold different prescriptions all in a single lens, letting you see clearly at varying distances. They are often prescribed to those with presbyopia, an age-related refractive error which causes difficulties seeing objects, particularly those near you.
