And when the wear is very serious, the above 4 kinds of conditions, often even polishing and polishing can not save the lens, can only stop wearing change processing, so be sure to wear the mirror review on time!
4, How to prevent it
The prevention method is mainly in the cleaning step, keep hands soft and clean, nails short and smooth, finger abdomen and palm without dead skin and calluses. Rub with soft finger abdomen when washing. When storing the lens, if you find the lens stuck vertically on the edge of the lens box, you can tilt the lens box and gently shake the lens box, so that the flowing nursing solution in the box will drive the lens until the lens sinks into the lens box. If this doesn't work, try putting a few drops of the solution on the concave side of the lens and repeating the previous steps will be easier. By all means, do not use your finger to "poke" the lens down, this operation is too evil! Pick the mirror, must spread a clean towel on the table, to prevent it from falling directly to the ground, the table top. When the lens falls on the floor or table, if the concave side is up, we should wet our finger with water or nursing solution, and then gently dip our finger into the lens. If the convex side is up, gently suck directly with the suction rod.
