Contact lenses are miraculous pieces of plastic that allow you to see without glasses. In most cases, contact lenses are used as a substitute for eyeglasses, allowing less of them. Contact lenses can also be used to treat certain diseases of the eye or can be used for cosmetic purposes to change the apparent color of eyes.
Success-contact lenses requires a "partnership" between the editor, ie, an ophthalmologist, an optometrist, or possibly an optician, and you, the wearer.
The installer must first decide if your eyes are healthy enough to wear contact lenses. In this case, the installer then fits the correct lenses for your eyes and your needs and teaches you how to use and care for them.
The installer must be available in case of problems to develop, if not available, then the installer must have a system in place to deal with these situations.
You must follow the care instructions, and wear your lenses properly, and return as required for routine care and emergency services.
