Contact lens, also known as contact lenses, are tiny thin lenses usually placed directly on your eyes. Contact lenses are versatile ocular prosthetics used by more than 150 million individuals world-wide, and they are often worn for corrective vision, for decorative or therapeutic reasons, or both. Contact lens use has been steadily increasing among adults, with more people discovering the benefits that contact lens have to offer. But contact lens use is not without risk.
The most common dangers in contact lenses is that they will improperly fit. This results in reduced vision and can lead to eye infections or even eye trauma if the fitting is poorly done. When the contact lens does not fit well, the result can be that some areas of your eye are covered while some are not, which makes it difficult for the eye to focus on an object. If the eye does not heal correctly after the contact lens is removed, it can result in pain, discomfort and even a loss of vision.
Types of Contact Lens
There are three basic types of contact lenses: Rigid gas-permeable lenses, permeable gas-permeable lenses, and polyps. Rigid gas-permeable lenses require a surgical process. During this process, a surgeon cuts a small flap in your cornea and inserts the contact lenses. The doctor must also prepare your cornea before the lenses are inserted to make sure that the cut is clean and smooth. Once the contact lenses are inserted, the corneal tissue is gently folded over the lens to seal it. Once sealed, the corneal tissue is allowed time to recover before the next round of surgery.
Permeable gas-permeable lenses require a different procedure. The only tools you will need to perform this treatment are disposable cotton balls and a few cotton swabs. In order to prepare your lenses, you will take a sterile cotton ball and dip it into a few drops of solution that disinfecting your lenses. After which, you will insert the contact lenses while the solution soaks in your lenses.
As with rigid gas-permeable lenses, a few days later your eye doctor will remove your contact lenses and check the progress of your eye condition. However, this treatment is typically more expensive than rigid gas-permeable lenses. Polyps in particular, are difficult to remove and can cause damage to your eye’s structure and function if they are left untreated for a long period of time. Once the eye doctor detects any signs of infection, corrective eye surgery may be necessary.
If you are experiencing any symptoms or complications from your contact lenses, consult your eye doctor immediately. Eye infections can sometimes be serious. It is important that you do not delay taking care of the problem as it can significantly impact your vision. Also, keep in mind that most eye doctors prefer to give their patients a few days away from contact lenses to allow the eye infection to run its course. However, if you notice signs of infection, do not hesitate to contact your eye doctor right away.
