Disposable Contact Lenses – Pros & Cons

Contact lenses, also known as invisible lenses, are thin, curved lenses placed directly above the cornea of the eye. Contacts are used to correct eyesight or for therapeutic or cosmetic reasons, and they are worn by more than 150 million individuals worldwide. Contact lense is made from a special blend of polycarbonate and eyelash-friendly silicone called Minoxidil. This ingredient enables contact lense to achieve its exceptional clarity, while minimizing glare and smudges that could mar the look of one’s eyes.

Contacts come in two basic varieties: soft contact lenses and hard contact lenses. Hard lenses require a replacement schedule, which is generally recommended to be changed at regular intervals, such as every week or every alternate month. Soft contact lenses can be replaced every two weeks. Although it is more expensive to replace them, it saves time because there is no need to take time out of work to visit your eye doctor to have your contact lens cleaned. Also, hard contact lenses can only be worn for up to two weeks before they must be discarded.

Both hard and soft contact lenses contain rigid gas permeable lenses that block some of the UV rays that hit the eye. As a result, they do not allow oxygen to reach the eye, which is critical for comfortable eyesight. This is why it is important to keep your eyes well oxygenated at all times, so you do not develop dry eyes or any other discomforting eye problems. It is also important to keep your contact lens clean at all times, to ensure that bacteria does not accumulate. Cleaning rigid gas permeable lenses is quite simple, as they often come with detailed cleaning instructions printed right on their packaging.

Contact Lenses differ from traditional glasses because they are not considered a functional vision aid. If you are not using them for the correct reasons, then they are not considered a functional corrective device either. Contact Lenses are only used during times when your vision is not perfect, such as having astigmatism, nearsightedness, farsightedness, presbyopia or any other vision problem. Many adults consider disposable contact lenses as an alternative to traditional eyeglasses. There are many advantages to using disposable lenses. For example, if your prescription has been altered by your eye doctor, or you are using them for other purposes than to improve your vision, then they may be considered a functional device.

Information

One of the most common problems associated with contact lenses is keratitis, which is irritation and inflammation of the eye. Keratitis is often associated with long term use of lenses. Constant re-contouring of the cornea and various eye care issues can cause contact lens wearers to experience constant irritation and inflammation of the cornea. Once the irritation and inflammation become chronic, as it is sometimes the case with people who wear lenses for extended periods of time, it can lead to loss of vision. It is important that anyone using lenses to treat a chronic condition such as keratitis make sure they have their eyes tested on a yearly basis by an independent eye care professional.

If you wear disposable lenses, the process of cleaning them is a very simple one. However, if you choose to use Invisalign or conventional lenses, it is a good idea to purchase and sterilize your cleaning supplies in advance. This will ensure you always have proper cleaning supplies on hand to ensure your lenses are free of contamination. If you have regular eye exams scheduled with your eye care professional, it may also be beneficial to allow him to keep a weekly diary noting the number of times each cleaning solution is used. This information may be very helpful in identifying areas where particular cleaning solutions could be beneficial.
