What are the Different Types of Contact Lenses?
When it comes to contact lenses, there are a variety of different types to choose from. In this blog post, we will discuss the different types of contact lenses , such as hard contact lenses, soft contact lenses and color variation. Each type has its own benefits and drawbacks, so it is important to understand what each one entails before making a decision. Let's take a closer look at each type of contact lens.
Hard Contact Lenses
The first type of contact lens is the hard contact lens. This type of lens is made from stiff plastic and fits over the entire cornea. There are two main types of hard lenses- conventional hard lenses and rigid gas-permeable (RGP) lenses. These types have different oxygen permeability, which is an important factor to consider.
Conventional Hard Lenses (PMMA)
Conventional hard contact lenses are the most common type of hard lens. They are made from a polymer called polymethylmethacrylate (PMMA). These lenses have been around for many years and are known for their high oxygen permeability. This means that they are a good option for people with dry eyes.
Rigid Gas-Permeable (RGP) Lenses
Rigid gas-permeable contact lenses are made from a different type of polymer called polysiloxane. These lenses have a higher oxygen permeability than conventional hard lenses, which makes them a good option for people with sensitive eyes.
Soft Contact Lenses
The second type of contact lens is the soft contact lens. These lenses are made from a flexible plastic and fit over the cornea. There are three different types of soft lenses, these are daily-wear lenses, extended-wear lenses and disposable lenses. Each type has different wear time and cleaning requirements.
Daily-wear contact lenses is a common type of soft lens. They are made from a flexible plastic and fit over the cornea. These lenses can be worn for up to 12 hours per day and must be removed at night for cleaning.
Extended-wear contact lenses are a type of lens that can be worn for up to 30 days. These lenses are made from a flexible plastic and fit over the cornea. They do not need to be removed for cleaning but should be checked regularly for deposits.
Disposable contact lenses are another type of soft lens. They are made from a flexible plastic and fit over the cornea. These lenses are thrown away after each use.
Another type of contact lens is color variation. This type of lens comes in three different types which are opaque, enhancers and visibility tinted. Each type has a different purpose.
Opaque contact lenses are lenses that are used to change the color of the eye. This have different variety of colors and can be used to create a dramatic look.
Enhancers are used to enhance the natural color of the eye. They are available in a variety of colors and can be used to create a subtle or dramatic look.
Visibility tinted lenses are used to make the lens more visible in the eye. These are available in a variety of colors and can be used to create a subtle or dramatic look.
Now that you know the different types of contact lenses, you can make an informed decision about which type is right for you. It is important to consult with an optometrist to find the best lens for your needs.
