Abstract

[Object] To provide a contact lens and storage medium capable of adjusting light to be transmitted through the contact lens.
[Solution] Provided is a contact lens including: a lens unit configured to be worn on an eyeball; an adjustment unit configured to adjust light to be transmitted through at least one of a first region that is a central portion of the lens unit and covers a pupil of the eyeball and a second region that is an outer side of the first region and covers an iris of the eyeball; and a control unit configured to control the adjustment unit in response to input of a trigger signal.

First claim

1 . A contact lens comprising:
a lens unit configured to be worn on an eyeball; an adjustment unit configured to adjust light to be transmitted through at least one of a first region that is a central portion of the lens unit and covers a pupil of the eyeball and a second region that is an outer side of the first region and covers an iris of the eyeball; and a control unit configured to control the adjustment unit in response to input of a trigger signal.

2 . The contact lens according to claim 1 ,
wherein the adjustment unit adjusts an amount of light to be transmitted through the first region of the lens unit.

3 . The contact lens according to claim 1 ,
wherein the adjustment unit adjusts a wavelength region of light to be transmitted through the first region of the lens unit.

4 . The contact lens according to claim 1 ,
wherein the adjustment unit adjusts at least one of a color and a pattern of the second region of the lens unit.

5 . The contact lens according to claim 1 , further comprising:
an image pickup unit configured to capture an image of a subject, the image pickup unit being provided in the lens unit.

6 . The contact lens according to claim 5 ,
wherein the control unit detects a particular gesture as the trigger signal on the basis of a captured image captured by the image pickup unit and controls the adjustment unit in accordance with the detected gesture.

7 . The contact lens according to claim 5 ,
wherein the control unit detects conscious eyelid closure as the trigger signal on the basis of a captured image captured by the image pickup unit and controls the adjustment unit in accordance with at least one of a time period, the number of times, and a pattern of the detected eyelid closure.

8 . The contact lens according to claim 5 ,
wherein the control unit detects a light amount as the trigger signal on the basis of a captured image captured by the image pickup unit and controls the adjustment unit in accordance with the detected light amount.

9 . The contact lens according to claim 1 , further comprising:
a communication unit provided in the lens unit, wherein the control unit controls the adjustment unit in accordance with the trigger signal received by the communication unit.

10 . The contact lens according to claim 1 , comprising:
at least one of a pressure sensor, a magnetic force sensor, a vibration sensor, and an acceleration sensor, wherein the control unit detects a sensing result of the sensor as the trigger signal and controls the adjustment unit in accordance with the detected sensing result.

11 . The contact lens according to claim 1 ,
wherein the adjustment unit includes a dye-sensitized solar cell.

12 . The contact lens according to claim 1 ,
wherein the first region of the lens unit has a diameter of at least 8 mm.

13 . A storage medium having a program stored therein, the program causing a computer to function as:
an adjustment unit configured to adjust light to be transmitted through at least one of a first region that is a central portion of a lens unit configured to be worn on an eyeball and covers a pupil of the eyeball and a second region that is an outer side of the first region and covers an iris of the eyeball; and a control unit configured to control the adjustment unit in response to input of a trigger signal.
