A seemingly very reliable and inclusive consideration of the contact lens which presumably provides optically superior vision although throughout who can or cannot, should or should not, wear them is indicated. The introductory section is devoted to the eye as a camera and the early history of this lens -- back to da Vinci. Most of the book deals with the everyday practicality thereof from the initial eye examination and fitting to the purchase (costs, insurance also); from adjustment and adaptation to care and upkeep as well as how long to wear them and when not (brushing your teeth -- using hairspray). At the close Miss McDonald deals with the vastly overstated soft lens -- she believes that it will ""probably not"" replace the hard lens although she does indicate its advantages -- for certain people and certain situations. A truly helpful book since certainly no professional could take the time to explain all this so well to the potential user and there are already ten million of them.
