Important Things to Consider Before Buying Contact Lenses
With so many options available to the consumer when looking for a contact lens, it might be really confusing as to which one to choose. There are many different kinds of contact lenses available in the market keeping in mind to suit the needs and wants of a person. The needs differ from a person to another and hence so many varieties are available. There are the soft and rigid varieties mostly used by the people for correcting the vision imparities. Soft lenses are easy to handle and adjust and are very comfortable when worn. They are made up of soft plastic material.
They fit the eyes properly, absorb and hold water too. Soft lenses do not pop up like the rigid lenses and also do not accumulate any dust underneath them. Rigid lenses on the other hand do not absorb chemicals, as in the case of soft lenses. They also give a clear view. Rigid lenses last longer and gas permeable lenses are less expensive than the soft lenses.
Both soft and rigid lenses are used for bifocal correction. Some models correct both near and distant visions while others, correct near vision in one lens and distant vision in another lens. It is very essential for the eyes to get rest without lenses at least for one night after scheduled removal. There are even the decorative and novelty lenses available in different shapes, colors and designs. However they should be approved by the FDA, and other-wise usage of such contact lenses might lead to even blindness. Extended wear lenses can be worn up to six nights or even up to one month’s time. However it depends on the lens’ type and the doctor’s evaluation of the person’s tolerance for overnight wear. Normally lenses are not worn during nights as they are not good for the eyes. There are rigid gas permeable lenses designed and approved for wearing all the night. Some eye care professionals prescribe disposable lenses as planned and replacement lenses, which can be removed, disinfected using the multipurpose lotion and reused again.
The right kind of contact lenses can be only determined by the eye professional after the examination of the eye. To purchase the right kind of lens you can rely on eye specialists, internet and wholesale retailers and before purchase, make sure the contact lenses suit you the most.
