Foreign studies have shown that when the eyes are concentrated on a fixed target, the adjustment of the eyes is not fixed at a constant, but at a certain level. Vibrate within the range. Just like an auto-focusing camera, these changes are called adjustment micro-vibrations, which cannot be felt and cannot be controlled by themselves. This is the normal state of the eyes. As shown in Figure A, when the eyes feel fatigued, these adjustment micro-vibrations The vibration will partly disappear, which means that the adjustment ability of the eyes is difficult to maintain. When the adjustment is excessive, the amplitude of the micro-vibration is ver y small, and the eyes are in a state of asthenopia, as shown in Figure B. If you add a pair of anti-fatigue to the eyes at this time The lens, adjust the micro vibration will be displayed immediately. As shown in Figure C, comparing C and B, you can see a significant change in the amplitude, indicating that after wearing anti-fatigue lenses, the eyes have recovered to a certain extent, and visual fatigue has been significantly improved.
