Similar to eyeglasses, prescription contact lens serves to correct refractive errors that the wearer has. However, contact lens is not a one-size-fits-all item. Different kinds of contact lens are suitable for different users. I-Vision Optometrist offers an assessment and fitting of contact lens to find the contact lens best suited for you. Contact lenses are considered as medical devices and must be prescribed by an eye care professional such as an optometrist or ophthalmologist. Since contact lenses have direct contact with the cornea, any mishandling can lead to infections which may ultimately lead to vision loss. New of existing contact lens wearers who do not have an eye check-up in the past six months will have to undergo the assessment for contact lens fitting. Complications for contact lenses may accumulate without symptoms, thus, it is important to detect any abnormalities early.
