摘要:
It is an objective of the present invention to provide a novel polymerizable triptycene derivative that has a structure in which three benzene rings arranged at the axis formed by barrelene of the triptycene skeleton can rotate evenly and that has hydrophilicity imparted to it as compared to any of the prior art triptycene derivatives and is thus highly useful in functional materials. The above objective is achieved by the polymerizable triptycene derivative having substituents with an unsaturated bonding functional group at position 9 and/or position 10 of the triptycene skeleton, the polymerizable triptycene derivative having two carboxyl groups and the polymerizable triptycene derivative having one carboxyl group and one amino group.

The object of the present invention is to provide an annular device superior to a conventional annular device in the stability over an eyeball when being worn, which overcomes problems caused by wearing a conventional annular device. The above object is attained by preparing an annular device to be worn over the surface of the sclera, the annular device including an opening exposing the cornea and one or a plurality of approximately encircling grooves on an intermediate part between an inner rim part and an outer rim part. The annular device has a maximum thickness preferably in the intermediate part.

The present invention aims to provide a ring-shaped device superior in the wearing comfort and intraocular stability while being worn on the eye. Provided is a ring-shaped device to be worn on the scleral surface, which is characterized in that it has an opening to expose the cornea and an intermediate portion between an inner edge portion and an outer edge portion has a maximum thickness.
