Prescription contact lenses are important devices that could significantly improve your vision and correct certain eye problems. These are very convenient and practical to use, which are the reasons why many people prefer these. But it’s also important to take note that you should always depend on your eye care specialist for the correct prescription contact lenses that you should wear.
Prescription contact lenses are made up of different types of materials, such as silicone, polymethyl methacrylate, polymacon or polymer materials. These are light in weight and virtually transparent, so it’s hardly noticeable. The three basic functions of contacts are to correct refractive vision defects, used in the treatment or management of certain medical eye problems, and as accessories for theatrical or movie purposes.
The common types of refractive eye disorders are hyperopia (farsightedness), myopia (nearsightedness), presbyopia (associated with aging), and astigmatism (corneal curvature defect). Depending on the policy of your country or state, optometrists and ophthalmologists are the only ones authorized to fit and prescribe any types of contacts based on your current problem.
Aside from its medical benefits, contacts are preferable because of the fact that these are more convenient to use. These are not affected by humid weathers or create mists, which are common problems with spectacles. Contacts also allow more freedom to do other activities with a wider field of vision (not just a straight and front angled vision). Besides, there are certain eye conditions that are not correctable by mere use of eyeglasses.
Contact lenses are regulated products, which mean you cannot buy these without acquiring any prescription from your eye doctor. As what has been mentioned, ophthalmologists or optometrists will evaluate your current condition; prescribe the correct fit, material, and brand that you should buy. You have the options of either buying directly from your eye care specialist or from a separate optical retailer store – just make sure that they strictly follow the prescription, including the brand (e.g. Acuvue, Biomedics contact lenses, Boston Xo contact lenses).
Common complications related to contact lenses with no prescription verification and improper care practices will often involve swelling, inflammation, pain, scraping of the cornea, and even blindness. That’s why (and it couldn’t be stressed enough) prescription and proper contacts handling should always be observed at all times.
Before and after handling your contacts, make sure that you’ve already done your hand washing. You should follow the prescribed way of wearing and cleaning of the lenses (that includes being aware of the proper wearing time and expiration date). Never wear your contacts when you sleep, unless they’re the extended-wear types. And wearing of UV-protected sunglasses is quite helpful in avoiding sunlight sensitivity.
Contact lens prescriptions pretty much expire after one to two years. That’s why you should visit your doctor at this time to update your prescription and check of any adverse effects caused by prolonged and continued use of prescription contact lenses.
These are just a few of the options available in prescription contact lenses.
