[0050] Example 2

[0051] This embodiment is a further improvement of Embodiment 1. In this embodiment, the wearable visual perception optimization device can be a visual perception optimization cap. Figure 1 The wearable visual perception optimization device may include: a lighting unit 200 and a wearable unit 100. The lighting unit 200 is used to project red light to the human eye. The wearable unit 100 includes a cap body 110 and a brim 120; the cap body 110 is used to be worn by a user, and the lighting unit 200 is arranged on the brim 120. Preferably, the lighting unit 200 is configured with at least a first light-emitting mode and a second light-emitting mode; the lighting unit 200 adopts the first light-emitting mode when there is ambient light, and adopts the second light-emitting mode when there is no ambient light.

[0052] The wearable visual perception optimization device provided in this embodiment installs the lighting unit 200 on the brim 120 of the hat, so that when the user wears the hat, the lighting unit 200 can be placed in front of the eyes through the brim 120, so that the lighting unit 200 can emit red light to the human eye, so that the proportion of red light in the light entering the user's visual perception is increased, and the proportion of blue light is reduced, thereby achieving the effect of eliminating or alleviating the negative impact of blue light on the human body in daily life; while achieving the blue light protection effect and improving the visual perception of the human eye, the human eye can still perceive blue light, which can avoid drowsiness or lack of energy due to lack of blue light.

[0053] Example 3

[0056] Preferably, the light emitted by the lighting unit 200 may be red light of a single wavelength or red light of different wavelengths.

[0057] The wearable visual perception optimization device provided in this embodiment installs the lighting unit 200 on the brim of the hat, so that when the user wears the hat, the lighting unit 200 can emit red light to the human eye, thereby reducing the proportion of blue light received by the human eye, thereby achieving the purpose of eliminating or alleviating the negative impact of blue light on the human body in daily life.

[0058] When using the wearable visual perception optimization device provided in this embodiment, the user can wear the wearable visual perception optimization device through the wearable unit 100; after wearing, adjust the brim 120 to the front of the forehead, that is, adjust the wearable unit 100 so that the lighting unit 200 is located in front of the user's forehead; then rotate the rotating bracket 230 so that the red light emitted by the lighting unit 200 enters the eyes.
