Abstract: The disclosure concerns a system and methods for detecting a body response to a visual stimulus. The system includes an eyewear delivering a left visual stimulus via a left side of the eyewear and a right visual stimulus via a right side of the eyewear. The system further includes a sensor configured to measure a body posture of a subject's body when the subject is wearing the eyewear. The system further includes a controlling circuit operably coupleable to the eyewear and to the sensor, so that when operably coupled, the controlling circuit: receives measurements of the body posture from the sensor, provides a body posture response information based on the measurements of the body posture, and determines a deviation of the body posture response information to a reference, where the reference is based on the left visual stimulus and the right visual stimulus.

Abstract: An aspect of the disclosure relates to an eyewear for a user seeing an image when wearing the eyewear. The eyewear may include a light adjusting means configured to provide a projection light which is perceived by a user's eye when facing a first surface of the light adjusting means, such that the user may see a modified image which is modified from an original image. The light adjusting means may be configured to provide a modified amount of positive contrast signal, for a retina of an eye of the user, in the modified image as compared to the original image.

Abstract: An aspect of the disclosure relates to a method of determining an attitude of an eyewear. The method may include: detecting a light signal reflected from the eyewear with a digital device including a light sensor for a non-visible wavelength range; and calculating, using the light signal, an attitude of the eyewear. The attitude may be at least one of: a yaw angle, a pitch angle, a roll angle. A second aspect of the disclosure relates to an eyewear including at least a first lens. The first lens may include a first coating having reflection in the non-visible range of wavelengths. The first coating may further include a pattern with an orientation. A third aspect of the disclosure relates to a computer program product including instructions, which, when the program is executed by a digital device, causes the digital device to carry out the method.

Abstract: An eyewear, comprising a first receptacle and a second receptacle; a first lens element received in the first receptacle; and a light sensor configured to detect incident light and provide a sensor signal based on the detected incident light. The eyewear further comprises an analysis module. The analysis module is operably coupled to the light sensor to receive the sensor signal from the light sensor, and operably coupled to the variable optical filter structure to provide a control signal to the variable optical filter structure. The analysis module is configured to control the optical state of the variable optical filter structure thereby adjusting an illuminance ratio of light transmitted by the first lens element to light transmitted at a position of the second receptacle. Further provided is a method for adjusting a variable optical filter system for an eyewear, and a method and computer program for controlling the eyewear.

Abstract: A system is provided, which is adapted for an eyewear and/or a spectacle lens. The system may be configured to actively control an amount of light at a point at a predetermined distance of the system, for example to switch between a first light intensity and a second light intensity. A spectacle lens is provided comprising system. An eyewear is provided comprising system. The system may be an illumination system which may comprise a light source configured to emit a first light and a second light, and further configured to emit pulses of light with a pre- determined time function. The pre-determined time function may include a plurality of packets. Each packet may comprise a pulse alternation between first light and second light. The system may be an optical filter system, which may include a band-cut filter. The band-cut filter may be configured to be in a band-cut filter state under a low light condition and not in the band- cut filter state under a high light condition.
