Contact lens, also known as contact lenses, are thin thick lenses usually placed directly on the cornea (the colored part of the eye). Contact lenses aren’t just for those with weak eyes; anyone who has a nearsightedness, farsightedness, astigmatism, or presbyopia can benefit from contact lenses. They are comfortable to wear, and most are disposable. There are a variety of styles and designs, including custom fit and size custom fit.
Contact lenses are therapeutic devices prescribed by an optometrist or ophthalmologist and may be prescribed for one or more reasons. One of the most common reasons is that vision has been diminishing gradually, with age. A doctor may prescribe corrective lenses to address the problem. For instance, when people lose weight, the muscle strength in their eyes drops, which impairs their ability to focus. Another common reason is that as we age, there is a gradual loss of lubrication in the eye, which weakens the lens and decreases its effectiveness.
Contact Lenses have two components – the lens itself and the optometrist’s gas permeable (GP) lenses. The GP lens is similar to regular glasses, in that it has a wafer layer and a soft silicone layer. The lens has a sealed surface and is designed to prevent moisture and air from reaching the eye; it also ensures that there is no significant loss of light through the pupil, so it retains most of the light that comes through the pupil. The soft silicone allows the oxygen to transfer from the eye to the lens, rather than the other way around. All this contributes to the higher comfortability of GP lenses for the patient, resulting in less eyestrain.
People often choose to wear contact lenses to correct their vision. This might be because they have seen a major improvement in their vision, such as a correction of one eye that has left them with astigmatism. It might also be because they have a long history of eye-sight issues, such as nearsightedness or farsightedness. Perhaps they are new to wearing eyeglasses, or perhaps their previous eyeglasses no longer provide the required vision correction. Whatever the reasons for wearing contacts, if you are considering doing this, then it is important to ensure that you have your eyes examined by a professional before you begin.
Because the eye is a sensitive organ that can easily be infected, it is important that contact lens wear is performed with care. It is essential that you follow recommended procedures for disinfecting your hands and ensuring that you are using sterile equipment to clean and store them. Remember that any infections, such as infections from bacteria, fungi or viruses, can result in additional risks, including pain and discomfort. If you are experiencing any of these symptoms, it is advisable that you contact your eye doctor right away to find out more about the possibility of harmful infections.
An alternative to traditional disinfecting and cleaning, which are often used by optometrists and ophthalmologists, is the use of a prescribed solution. Usually, there is an appropriate solution that will kill the bacteria and remove other microorganisms that are present on and in the eye. There are a number of solutions available, including antibiotic solutions that are applied topically. In addition, there are a number of eye drops that are specifically designed for this type of application. Once again, it is important to remember that these are prescribed and should only be used under the supervision of your doctor.
