The distance between the lenses is for a "standard" person. Generally, this will not be a problem, but if a patient is sensitive or has more closely set eyes, for example, it may pose a problem. Persons buying ready-made ocularhealthcontactlenses sunglasses or reading glasses should hold them up to see if they appear clear. They should also hold ocularhealthcontactlenses the lenses to see an object with straight lines reflected off of the lenses. If the lines don''t appear straight, the lenses may be warped or inferior.Patients may sometimes need a few days to adjust to a new prescription; however, problems should be reported, because the glasses may need to be rechecked.contact The primary drawback to wearing contact, especially for children, is the requirement that they be cleaned and disinfected daily in order to prevent an infection, which could result in permanent damage to the eye. Careful choice of lenses and consistent lens care will minimize the risk of infection. Wearers of best lenses are the least ocularhealthcontactlenses prone to infection but the lenses are much less comfortable, more expensive, and can pop out of the eye more easily than lenses. Daily wear lenses put the wearer at a slightly higher risk of infection because they absorb more external liquids and airborne contaminants. (Lenses made from polycarbonate, the same type of plastic used for the space shuttle windshield, are about 50 times stronger than other ocularhealthcontactlenses lens materials.) ocularhealthcontactlenses Also, ocularhealthcontactlenses people at risk of receiving electric shock should avoid metal frames.People employed in certain occupations may be prohibited from wearing contact, ocularhealthcontactlenses or may be required to wear safety eyewear over the contact. Some occupations, such as construction or auto repair, may require safety lenses and safety frames. Physicians and employers should be consulted for recommendations. Description Eyes are examined by optometrists (O.D.) or by ophthalmologists (M.D. or D.O.--doctor of osteopathy). Prescriptions, if necessary, are then given to patients for glasses. The glasses are generally made by an optician. A separate ocularhealthcontactlenses lenses-fitting exam is necessary if the patient wants contact, because an lenses prescription is not the same as a lenses prescription.
