"Zera" Frame in Matte Black
These great readers have built-in different magnification zones so you can wear the same readers all day and not have to take them on and off numerous times!
The same pair of readers can be used for:
Across your desk: Half normal strength – half magnification for across the desk viewing (weak strength)
Computer: Slightly less than normal strength – slightly less magnification (medium strength)
Reading: Normal reader strength – reading books, smartphones, other close up work (strong strength)
They have a 5-layer anti-reflective coating to reduce glare, and UV380 protection.
For the 2.75 strength readers, the strength on the top of the lens is +1.38, and at the bottom they are +2.75.
For the 2.00 strength readers, the strength on the top of the lens is +1.00, and at the bottom they are +2.00.
