Adjustment of the upper and lower position of the nose pad
The nose pad can be pulled up and down with the pliers of the nose pad to achieve the purpose. You can use needle-nose pliers to clamp on the nose pad and apply torque in a certain direction to change the upper and lower position of the nose pad. When applying the torque, the nose pad can be pressed down or pulled up by the pliers to change the position of the deformation of the bracket, to prevent repeated deformation and fracture near the solder joint.
Do night driving glasses work?
Yellow lenses reduce the amount of light entering the eyes, thereby reducing visibility. At night, this may be harmful, not beneficial.
Night driving glasses are available in a variety of yellow and amber colors. The darkest lens filters out the most glare, but also filters out the most light, making it difficult to see in dim or dark conditions.
Some night-driving glasses wearers report that they can see better when they wear them at night. However, visual tests have shown that night driving glasses do not improve night vision, nor can they help the driver see pedestrians faster than without them.
Glasses donation is also a form of recycling.
The old glasses were donated, and the love glasses were favored and recognized by the public. It is mainly aimed at orphans, left-behind children, single-parent families, and adolescents with mental retardation in poor mountainous areas.

Encourage them to take good care of their eyesight, study happily and grow healthily. And it can enhance the self-health care consciousness of young students.

How do you identify the refractive index of lens?
In reality, this problem is often a problem for optical shop practitioners, sometimes they worry about whether the manufacturer's lenses match the nominal value of the refractive index. We need a prop, and that's the camber. Because it can be used to measure the strength of the lens. The luminosity of the lens can be calculated by subtracting the curvature of the inner and outer surfaces of the lens. The curvature difference of a lens of the same luminosity is inversely proportional to the refractive index, that is, a lens with a higher refractive index only needs a smaller curvature difference to achieve the same luminosity.
