1. At least one non-transitory machine-readable medium having stored thereon data which, when used by at least one machine, causes the at least one machine to perform operations comprising:
adjusting a refractive index of an optical lens from a first refractive index value to a second refractive index value, wherein the refractive index changes in response to a change in an electrical property of the optical lens;
in response to adjusting to the second refractive index value, receiving a first communication regarding a first eye accommodation of a user;
determining a first amount of time between adjusting the first refractive index value to the second refractive index value and receiving the first communication regarding a first eye accommodation of the user;
adjusting the refractive index from a third refractive index value to a fourth refractive index value;
in response to adjusting to the fourth refractive index value, receiving a second communication regarding a second eye accommodation of the user;
determining a second amount of time between adjusting the third refractive index value to the fourth refractive index value and receiving the second communication regarding a second eye accommodation of the user;
wherein the first amount of time is less than the second amount of time.
