  • Publication number: 20140159397
    Abstract: Disclosed is a contact-lens putting support tool including a rod-like handle portion held by fingers of a wearer of a contact lens and a head portion for causing the contact lens to adhere thereto through a liquid to take out the contact lens from a container, the contact lens having a front surface thereof wet with the liquid. A lower part of the handle portion is flat such that the contact-lens putting support tool is softly placed on a flat surface. The head portion is directed obliquely upward with respect to an axis formed by the handle portion, is curved downward, and has a spoon-like shape of which upper and lower surfaces are rounded. A convex surface of the contact lens having a concave surface thereof adhering to the lower surface of the head portion is placed at a predetermined position of a contact-lens putting tool.
