Electronic device and screen adjusting method based on condition of user's eye

An electronic device comprising:

• a display screen;
• a storage device;
• at least one processor;
• and
• the storage device storing one or more programs, which when executed by the at least one processor, cause the at least one processor to:
• obtain a pupil image of a user of the electronic device;
• determine an eye condition of the user by analyzing the pupil image;
• adjust proportions between a red channel, a green channel, and a blue channel (RGB) of the display screen according to the eye condition;
• obtain an eye image of the user;
• determine eyes of the user are closed by analyzing the eye image;
• inactivate the display screen when the eyes of the user are closed;
• determining the user has eye disease when a grayscale of a first predetermined portion of the pupil image is within a first preset range;
• determining the user not has eye disease when the grayscale of the first predetermined portion of the pupil image is within a second preset range, wherein the second preset range is different from the first preset range;
• determining the user has eye disease when a red chroma of a second predetermined portion of the pupil image is within a third preset range;
• determining the user is wearing contact lens when a blue chroma of the pupil image is within a fourth preset range;
• record a start time when the user is determined to be wearing contact lens;
• obtain a first pupil image of the user when the start time is recorded;
• obtaining a second pupil image of the user when a time length calculated beginning from the start time equals a preset time length;
• determine the user has been wearing contact lens for the preset time length when the user is determined to be wearing contact lens both in the first pupil image and the second pupil image;
• and
• transmit a prompt when the user is determined to have been wearing contact lens for the preset time length.
