Bio-focal glasses
"cannot use - causes eye strain and blurred vision"

Enhance your style as well as your sight with Margo Pop of Power® Bifocal-Style* reading glasses.
These sophisticated readers have a versatile square frame made out of milky white tortoise polycarbonate, with similarly strong and comfortable spring hinges.
Each lens features a magnified reader segment at the bottom; the rest of the lens is unmagnified.
The whole lens helps to filter blue-violet light* from the sun and artificial sources, including digital devices.
So, you can keep your glasses on—and your vision clear—when you shift between reading and looking up to see across the room or interact with others.
*Incorporates a patented lens technology that filters at least 30% of blue-violet light. The percentage refers to the average amount of blue-violet light (between 400-455nm as stated by ISO TR 20772:2018) filtered as measured in 5nm increments. Covered under U.S. Pat. No. 8,360,574. Other U.S. and foreign patents pending.
**Bifocal style readers have unmagnified lenses which also contain inserts with the magnification of your choice in the lower portion of the lenses.
