Progressive multifocal lenses refer to lenses where the diopter gradually increases from the bottom (near vision) to the top (far vision), with the diopter at the top of the lens (far vision) being 0.The degree you purchased is the degree at the bottom of the lens (look carefully).PD (pupillary distance) value is 62±2mm/2.44±0.07inch. For new wearers, how to quickly adapt to new progressive lenses: Stop wearing old glasses.
The top area of the lens is used for distance vision, it provides maximum visibility.As you look further down, the lens magnifies, allowing you to see more clearly up close. To see an object, please turn your head and look directly at it (don't just move your eyes).Then simply raise or lower your chin until the object is in focus.
Adaptation process: first try sitting in front of a clear TV, then reading while seated, then try wearing it while walking indoors, then going up and down stairs, finally wearing it while walking outdoors. If you feel that the progressive lenses hurt your eyes, please take a break.Then, reapply them.As time goes by, wearing them will become more comfortable.
When you first wear this type of glasses, you may experience blurred or distorted vision.However, the more lenses you wear, the faster these symptoms fade away.Give them a chance to work.You'll be happy you did it.
