The wear resistance of resin lenses mainly depends on the film layer, which has little to do with the material. Because the film layer is in direct contact with the external force, if the film layer is damaged, the lens cannot be used, and it is useless if the material is steel.
The human eye needs to use the adjustment power to see close. The closer the distance, the more adjustment, and the longer the time, the more tired. Therefore, try to keep the distance as close as possible, and do not use your eyes continuously for a long time. -3.00 degrees theoretically can only be seen clearly within 33 cm. It is recommended that people above -3.00 should wear glasses when looking at close-up. One sentence summary: "When you can't see clearly, you should wear glasses." This sentence is suitable for all myopic people.
