Contact lenses is like sunglasses too!
Contact lenses, also known as translucent lenses placed directly upon the cornea of the eyes. Contact lenses are used by more than 150 million individuals around the world, and they are often worn for aesthetic or corrective reasons or to correct vision. There are different types of contact lenses available, and these include full eye wear, disposable wear, and wear over the eye like sunglasses. Some people even wear contact lenses to correct their vision.
The first thing to consider when choosing contact lenses is what type of vision correction the patient needs. There are three options – one that covers near vision only, two that cover either distance or both. Each type of corrective will have a different correction method, such as increasing the power of the lenses as the patient blinks, decreasing the time the contact stays in place during the wearer’s waking hours, providing higher levels of protection from UV light, eliminating some reflections, etc. It is important that the optometrist or doctor determines what correction method is most suitable.
Next, it is important to consider which areas of the eye need correction. Some patients may benefit from gas permeable lenses, which allow some amount of light to pass through the lens, improving visual clarity. Other people may require toric contact lenses, which help the patient see near objects clearly but give little visibility over distant objects.
Consult an optometrist that will determine a proper lenses that fits for you
Once the individual has determined what correction method they are seeking, they can either choose to wear corrective contact lenses throughout their life, or they can choose to wear a contact lens solution. Both methods provide the same benefits, but contact lenses that are worn continuously for an extended period of time may be more expensive than those that are only worn periodically. In addition, contact lenses that are constantly worn tend to lose strength over time, which requires that the wearer replace them more frequently.
One important issue that must be addressed is infection. Infections, while rare, do occur with contact lenses and may cause significant discomfort. The most common infections are microbial, which usually occurs when an individual wears a non-disposable contact lens for an extended period of time without properly cleaning the lenses.
infections can lead to infections of the eye itself and even blindness
A physician or optometrist can diagnose these infections and treat them accordingly. To prevent infections, individuals are advised to clean their lenses regularly with multipurpose solutions such as multipurpose solution and Oxiclean.
As with any contact lens, proper care and hygiene must be taken to ensure that vision is not impaired and that the patient receives maximum visual benefit, regardless of whether they wear corrective or non-corrective lenses. While contact lenses can provide many benefits, individuals are strongly cautioned against wearing them for extended periods of time, as they may reduce the patient’s ability to properly focus on their surroundings. For this reason, many patients choose to wear rigid gas-permeable lenses for all times, until their eyes have fully recovered from their eye injury or illness.
