Abstract

An improved contact lens of the present invention, which keeps the eyes moist, avoids irritating the eyes, improves the comfort of fitting, and provides stabilization, comprises: a body with a circumference; at least one pattern located near the circumference, and a maximum width of the contact lens is less than a maximum value in such that the contact lens can avoid being restricted by eye muscles while fitting onto eyes.

Claims

1. A contact lens comprising:

a body with a circumference; and

at least one pattern deposited near the circumference of the body that creates a plurality of contact portions in a radial direction between the contact lens and an eye, wherein a maximum width of the contact lens is less than a maximum value such that the contact lens avoid being restricted by eye muscles while fitting eyes, and a ratio between a maximum distance from the circumference of the body to an edge of the pattern in the radial direction passing through a central point of the body and a maximum distance from the central point of the body to the circumference of the body is between 1;

2 and 1;

400.

2. The contact lens of claim 1, wherein the maximum value is less than 18 millimeters.

3. The contact lens of claim 2, wherein the contact lens is rigid lens, and the maximum value is less than 12 millimeters.

4. The contact lens of claim 2, wherein the contact lens is soft lens, and the maximum value is less than 16 millimeters.

5. The contact lens of claim 1, wherein the ratio is between 1:

4 and 1;

100.

6. The contact lens of claim 1, wherein the pattern comprises a plurality of waves.

7. The contact lens of claim 1, wherein the pattern comprises a plurality of arcs.

8. The contact lens of claim 1, wherein the pattern comprises a plurality of angular-shaped units.

9. The contact lens of claim 1, wherein the pattern comprises a plurality of angular-shaped units with round corners.

10. The contact lens of claim 1, wherein the pattern can be formed with a plurality of square-shaped units.

11. The contact lens of claim 1, wherein the pattern comprises a plurality of square-shaped units with round corners.
