Benefits of MR Lenses

It is made of MR series material of Mitsui Chemical, Japan. The biggest advantage is that it is both thin and has good optical properties. Besides, the material has good impact resistance and toughness, so it is not easy to be deformed or broken. Wearing such lenses not only looks more beautiful, but clear and comfortable, and safe at ease. Using a lower density polyurethane material, the lens is lighter and thinner, making it more comfortable to wear. The higher machining success rate increases the processing efficiency and reduces the processing cost. The film compatibility and dyeing properties of MR™ are better than those of ordinary materials, which can improve the quality of functional lenses like photochromic lenses and myopic sunglasses. MR-8™ combines high refractive index, high Abbe number (for better imaging), and better processing performance, suitable for rimless, half-frame, and other glasses, which are less broken and safer. MR-7™ provides better dyeing performance, faster and more uniform color application, and can be used for myopic sunglasses. MR-8 Plus™ is safer and further improves the impact resistance of the lens while maintaining the high Abbe number of MR materials.



Buy Glasses For Kids - Proper Lens

The size of the lens mainly determines the size of the eyeglasses. The outer edge of the rim of the lens should be on the outer edge of the orbital bone. If it is larger than the face, the rim of the lens frame will be too big. If the lens is only as big as the eye, the frame can easily deform. Resin and hard lenses should be considered first because glass lenses are fragile and easy to damage children's eyes. Resin lens mainly needs the accuracy of the axis of scattered light. The matched luminosity must be accurate. There are no scratches, no bubbles, and no impurities on the lenses. The degree of the lens selected for the child must conform to the quality testing standards promulgated by the state, and the error of the diopter should be within the range of the requirements of the national standard.
