Disadvantages of contact lens
Once the Contact Lens are placed over the eyes, there will be increased tearing, lid irritation, excessive blinking. It is a matter of getting used to an unaccustomed set of sensations. By the end of one week the contact lens wearer is usually no longer aware of the lenses on his eye except when he thinks about it. About the only real disadvantage in wearing contact lenses is the process of getting used to them. Once the wearer has become accustomed to all day use of contact lenses, he will find it difficult to name any disadvantage of importance.
