Hi tech adjustable strength reading glasses in a modern plastic frame work by adjusting 2 dials that focus each eye independently.
5-18" x 1-1/2" for SMALL faces to small-average
SHOULD NOT BE USED FOR DRIVING OR OTHER HIGH RISK ACTIVITIES!
Packaged in hard plastic case
Power ranges from -6.0 to +3.00. For long-sightedness, short-sightedness and presbyopia only
How does it work? 2 layers of lenses slide over each other with the twist of a dial, changing the overall thickness and consequently focus.
Not intended for astigmatism, and not intended to replace the need for regular eye health examinations.
Who should use this? Someone who uses different reading glasses throughout the day for different tasks, ie- viewing the computer, reading the newspaper, fixing jewelry require different focus. You can adjust the strength of these glasses for the different tasks. Also, someone who lost their distance glasses and needs an emergency pair. This is intended as a SHORT TERM temporary fix if used for distance wear.
The lenses are NOT scratch resistant, so handle with care!
Though these glasses are NOT UV or anti glare, some people may like to use them for the computer because you can adjust the strength a little weaker. People on average need less magnification to view their monitors as they do for regular close up reading.
