Claims

[Scope of utility model registration request]

So that each linear part is located on the center line that divides the contact lens for astigmatism into left and right halves.
The linear portions extend from the upper and lower edges of the lens toward the lens center of the lens, respectively, to provide an upper center mark and a lower center mark, and the lower center of the lower half of the lens. On both sides of the mark, linear portions form a predetermined angle with the linear portion of the lower center mark, and the linear portions extend from the periphery of the lens toward the center of the lens, 1. A toric contact lens, characterized in that the angle marks are provided with at least one angle mark, and the shapes of the angle marks and the lower center mark are made different from each other so that they can be identified from each other.
