Modern innovations in eyewear have made it possible for practically anyone to wear contact lenses. Of course, it’s important for you to know which particular type of contact lens is best suited for you. If you have problems with your eyesight, then you definitely need contacts that aid in your vision. If you wish to use purely cosmetic contact lenses, you’ll have to make sure they don’t distort your vision in any way. Here are the eight types of lens you can choose from:
- Soft Lens – This type of lens is made from polymer or plastic. Its main characteristic is that it allows oxygen to easily pass through. Its biggest advantage is the comfort it offers and its ability to filter harmful ultraviolet rays. The disadvantage with soft lenses, however, is that they don’t last for very long. They need to be replaced every 2-4 weeks.
- Hard Lens – As the name suggests, this type of lens is diametrical to the soft lens. It does not allow the passage of oxygen, which is why it is generally discouraged. This type of lens is prescribed only for very special needs.
- Rigid Gas-permeable (RGP) – This type of lens is also made of hard plastic, but it is a bit flexible to allow oxygen to pass through. Its biggest advantage is that it combines the comfort of a soft lens with the durability of a hard lens. The disadvantage is that this type of lens slips off center more easily than others.
- Daily Disposables – The biggest advantage of disposable cosmetic contact lenses has to do with hygiene and safety, since the fact that you replace them daily means you’re always wearing a fresh pair. It is also convenient, since no cleaning is required. The disadvantage is that it may not correct vision problems and is generally costly to use.
- Extended-wear Contacts – This type of lens is made from a special material that enables you to use a pair for up to 30 days. Its biggest advantage is that you’re less likely to suffer from dry eye irritation when using it. The disadvantage is that it can increase your risk for corneal ulcers and infections.
- Colored Contacts – As the name suggests, this type of lens is tinted. This is the type that’s often used for purely cosmetic purposes, as it can give you a completely different look.
- Bifocal Lens – This is a special type of lens that’s ideal for people suffering from presbyopia. It is available both in soft and RGP versions, and can help correct both farsightedness and nearsightedness.
- Toric Lens – This is also a special type of corrective lenses for people suffering from astigmatism. They are also available both in soft and RGP versions.
Now that you know what types of corrective and cosmetic contact lenses are available, you can make an informed decision as to what type of lens is best suited for you and you can finally take other considerations such as brand and price.
