Abstract: The photochromic helmet visor includes a transparent piece, an adhesive layer attached to the transparent piece, a flexible base layer attached to the adhesive layer, a self-repairing layer attached to the flexible base layer, and a number of photochromic elements integrated with the flexible base layer or the self-repairing layer. The self-repairing layer includes a. PU layer and a. Siloxane layer attached to the PU layer. The photochromic elements are integrated with the flexible base layer or the self-repairing layer. The flexible base layer is made of PU, TPU, PVC, or PET, and may be tightly and smoothly joined to the transparent piece along with the adhesive layer. The self-repairing layer allows self-repairing to scratches or abrasions under a high temperature, thereby preventing the malfunction of the photochromic elements out of wear and usage and the resulted constant replacement, and enhancing the visor's durability.

Abstract: The invention is related to the structure of the screen protector adhered on a screen. The screen protector comprises a surface film layer made of PET or PMMA. The peripheral bottom of the surface film layer is covered by at least one printed adhesive layer. At least one ventilation portion is defined between the printed adhesive layers, wherein the printed adhesive layer comprises a printed layer covered beneath one side of the surface film layer and an attaching adhesive layer covered beneath one side of the printed layer. A gap is defined between the surface film layer and the screen, wherein the gap is connected with the ventilation portion. The design of the ventilation portion and the gap may help the air flow to prevent introducing the Newton ring besides protecting the screen and so as to achieve the practical improvement.
