Eye safety and clinical treatment of eye disease.

1, the lens transmittance and optical uniformity test method: hand-held lens from the eyes about 30 cm, from the lens to observe the distance. If the vision is clear, no deformation, and slow movement without jump, indicating that the lens transparency and optical uniformity is better.
2, the optical center position test method: white paper with a fine line to draw a big cross, strokes to be clear and straight. Hand-held lenses, with one eye from the lens to observe the shape of cross-stroke. If the mirror mirror outside the stroke is not a line, can move the lens, so that the lens inside the cross strokes and the mirror into a line. With a soft pen in the lens observed in the center of the cross point a small point, this point is the optical center. After the two lenses point out the optical center,Acetate Eyeglasses observe the two sides of the optical center is symmetrical, and then use the ruler to measure the distance between the two centers is consistent with the prescription of the pupil distance. If the cross pen in the lens is bent, there is a quality problem with the lens.
