Product description
Photochromic Reading Glasses Men Progressive Multifocal Reading Glasses TR90 Glasses
The intelligent color-changing feature provides good light-transmittance and clear vision.
Principles of discoloration: In ultraviolet light, the radiation will cause a chemical reaction that changes the lenses uniformly.
Progressive multifocal lens means that the diopter from the bottom(see near) to the top(see far) of the lens is gradually increased, and the diopter at the top(see far) of the lens is 0. The degree you buy is the degree at the bottom of the lens (look closer) .The PD (pupillary distance) value is 62±2mm/2.44±0.07inch.
For new wearers,How to adjust quickly to your new Progressive Lenses:
Stop wearing your old glasses.
The top region of your lenses is for distance vision, and it provides the most visibility. As you look further down, the lenses magnify,allowing you to see better up close.
To look at an object, turn your head and look directly to ward it (do not just turn your eyes). Then simply raise or lower your chin until the object comes in to focus.
Adaptation process: first try to sit in front of a clear TV-then sit and read a book-then try to wear it when walking indoors-then go up and down the stairs-and finally wear it when walking outdoors.
Take a break from your progressive lenses if it feels like they're hurting your eyes. Then, reapply them. It'll get more comfortable to wear them over time.
When you first get this type of eyewear, you may experience blurry or distorted vision. However, the more you wear the lenses,the faster these symptoms will subside. Give them a chance to work. You'll be happy you did.
