Specification AgeRangeDescription : little_kid Brand : McbeAn BulletPoint1 : 【Function】You can observe the light and dark stripes of the lens, the force distribution during the injection molding process, and check the changes in installation force and the difference between genuine and fake crystal lenses. BulletPoint2 : 【How to use】 Place the glasses to be tested between the analyzer and polarizer of the stress meter, observe the stress around the spectacle lenses in the lens ring from top to bottom, determine whether the stress around the spectacle lenses is uniform, and determine Areas that need correction. BulletPoint3 : 【Durable】Desktop Polarizer It has a built-in light source, runs on AC power, and provides long-lasting, ideal illumination. The lens can be placed directly on the lens holder for observation, which is simple and easy to use. BulletPoint4 : 【One-button operation】One-button operation, plug in the power and press the switch to use. Energy saving; easy to use, fast and efficient. BulletPoint5 : 【Application】Suitable for major optical shops, vision care centers, hospitals, optometry training centers, etc. to detect the stress status of glasses, determine the authenticity of crystals, and be used for glasses production and testing.
