The invention discloses an optical film with an anti-dazzle self-repairing function. The optical film comprises a base material layer, a bottom coating layer and an anti-dazzle self-repairing layer which are sequentially stacked, according to the optical film provided by the invention, excellent anti-dazzle and self-repairing performance can be provided through the anti-dazzle self-repairing layer, and meanwhile, the anti-dazzle and self-repairing performance can be improved through optical activity provided by carbon dots in zirconium oxide-based composite anti-dazzle particles of the anti-dazzle self-repairing layer (active oxygen substances with an antibacterial effect are generated under illumination) and the antibacterial effect provided by zinc particles; the optical film can be endowed with long-acting antibacterial performance; the effects of blocking, buffering, improving adhesive force and the like can be provided through the bottom coating; according to the invention, through the barrier and anti-aging enhancement effects provided by the priming coat, the accelerated aging of the substrate layer caused by the entry of active oxygen substances generated by the anti-dazzle self-repairing layer under illumination into the substrate can be effectively avoided.

The invention discloses photocatalyst fluorescent ink, and relates to the technical field of ink. According to the invention, the self-made fluorescent agent is frozen into microspheres, and titanium dioxide is adsorbed on the surface of the self-made fluorescent agent by using plasma, electrostatic spraying and microwaves, so that the stability of the ink is improved; then, through low-temperature plasma assisted radio frequency magnetron sputtering, cerium oxide is coordinated and chelated on the surfaces of the titanium dioxide microspheres, so that the visible light activity of titanium dioxide is improved, and ink can be catalytically degraded under visible light; wherein the self-made fluorescent agent is prepared from veratrone, pyrenecarboxaldehyde and boron trifluoride, so that the ink can display patterns only under infrared wavelength irradiation, is not easy to decompose by illumination under long-time infrared irradiation, and has better light stability. The photocatalyst fluorescent ink prepared by the invention has the effects of good confidentiality, light stability and degradability.

This application discloses a method for monitoring eye use behavior, smart glasses, and a readable storage medium, relating to the field of wearable device technology and applied to smart glasses. The method includes: collecting user eye use behavior data through a multimodal sensor, and accumulating the near-field eye use time based on the eye use behavior data; outputting an alert signal when the accumulated near-field eye use time reaches a preset alert threshold; responding to the alert signal, monitoring the user's relaxation behavior through the multimodal sensor, including distance viewing, outdoor activities, and light activity; and resetting the accumulated near-field eye use time to zero when the duration of any relaxation behavior reaches a preset threshold, so as to re-monitor the user's eye use behavior. This application improves the accuracy of eye use behavior monitoring.
