Abstract
An eyeball microscope used for observing cornea endothelcells and the like, having an objective lens structure including an optical tip member which is formed of a material with lower refractive index than glass in order to avoid the undesired effect of reflection of illuminating light from the front surface of the optical tip member, and an adaptor for stably holding an impregnating liquid between the optical tip member and the cornea; the use of which will result in substantial reduction of reflection from the cornea surface and a corresponding increase in the field of view and resolution.
