Blue Light from Cell Phones Can Cause Chronic Retinal Light Injury: The Evidence from a Clinical Observational Study and a SD Rat Model

Figure 3

Introduction of the blue light illuminator model for the cell phone array. (a–c) Polyethylene PP feeding cage, with nine blue light bead illuminators on the top cover. (d) The illumination measured by the zd-10 illuminance meter at the four corners and at the midpoint of the four sides of the experimental box bottom 20 cm away from the illuminator light source was 5.0-5.2 lux, with an average illumination of 5.0 lux and a fluctuation range of 5%. (e, f) The model simulating the blue light illumination of cell phones.
