Rear view reflective glasses
A special kind of glasses. The front view is no different from ordinary glasses. After wearing, you can clearly see the situation behind you through the outside of the lens, so that the detective can look forward and backward easily and beware of being counter-tracked. As far as tracking and monitoring are concerned, it can work behind the monitored object, but also in front or side of it, which has a better concealment effect.
The chemical name of “space lens” is polycarbonate, also known as PC resin sheet. It has the following super performances:
1. 57% lighter than traditional glass sheets;
2. Safe, its impact resistance is 60 times that of glass sheets and 10 times that of ordinary resin lenses. When the thickness reaches 2.5cm, it can be used as bulletproof glass;
3. Lighter and thinner than CR-39 lens with the same optical index;
4. The ability to resist harmful rays is stronger than CR-39;
However, the “space lens” is not without its shortcomings, because its surface hardness is relatively low, so it is easy to scratch if you are not careful in use, at this point it is not as good as CR-39. However, due to the continuous progress and improvement of science and technology, the world’s major lens manufacturers are using various methods to improve this shortcoming of “space lens”. So the “space lens” already has the value that everyone expects. We might as well try the feeling of “space”!
