Zusammenfassung:The utility model relates to a contact lens anastomotic with a cornea. A cornea of an eyeball is divided into a plurality of blocks by a virtual axis from the center of the eyeball; a plurality of reference points are arranged on each block according to the concave-convex structure on the cornea of the eyeball; then forming a rear mirror surface contact lens with a smooth curved surface along eachreference point; the contact area between the cornea and the contact lens is increased in a concave-convex combination manner, so that the goodness of fit between the lens of the contact lens and thecornea is increased, the contact lens is prevented from moving when blinking or rotating eyeballs, and the contact lens is kept at a position required by human eyes. 本实用新型涉及一种吻合角膜的隐形眼镜,其主要是利用虚拟轴以眼球中心将眼球的角膜分隔出多个区块,并于每个区块上依据眼球角膜上的凹凸结构设置多个基准点,然后沿着各基准点形成具有平滑曲面的后镜面隐形眼镜镜片,以通过凹凸结合的方式增加角膜与隐形眼镜的接触面积,进而增加隐形眼镜镜片与角膜的吻合度,防止眨眼或转动眼球时,隐形眼镜出现位移的状况,以将隐形眼镜保持在人眼的所需位置上。
