SYSTEM AND METHOD FOR MONITORING CHANGE OF INTRAOCULAR PRESSURE AND CONTACT LENS FOR SENSING CHANGE OF INTRAOCULAR PRESSURE
First Claim
1. A contact lens for sensing change of intraocular pressure, comprising:
- a first material layer, wherein the center of the first material layer has an optical region, and the optical region corresponds to a cornea area of an eyeball; and
a first pattern, formed on the optical region, the first pattern being formed of a plurality of sub-patterns arranged at intervals.

Abstract
A system and a method for monitoring change of intraocular pressure and a contact lens for sensing change of intraocular pressure are provided. The contact lens includes a first material layer and a first pattern. The center of the first material layer has an optical region, and the optical region corresponds to a cornea region of an eyeball. The first pattern is formed on the optical region. Furthermore, the contact lens may further include a second material layer and a second pattern. The second material layer is located on the first material layer. The second pattern is formed on the second material layer and overlaps with the first pattern to form a moire pattern.
