    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day


    Fits over prescription glasses (wire frames)
    High quality optics
    Sturdy construction
    If used with sunlight or high-intensity lamp, LED not necessary.


    Fit of lens into holder could be problem, long term
    Excessive pressure on seating lens into clip could cause plastic to fail, sooner or later
    LED apparently intended for intermittent use, only
    Don't forget to turn switch off, when extral illumination is no longer needed!
    Screwdriver (included) not the right size to open battery-compartment screws.


    Plastic clip to retain lens is molded with an extremely tight fit. Understandable, since if it were the other way, the lens would slip or fall out. But, it is so very tight, repeatedly flexing clip by interchanging lenses is likely, over time, to crack the plastic clip. Solution: with a very small file, reduce peak of lens-retention bums on black plastic clip. Continue only until lens seats into clip with a faint click, under moderate pressure. Try not to flex clip itself when seating lens by keeping one finger on top of the clip, with other fingers pressing of bottom edge of lens.


    A worthwhile optical aid for anyone who does fine or detailed work. If you use it with bifocals, the distance part of the lens works best. Move (carefully, held only with single glue drop) the nose-support wires together. This will elevate the frame enough to make sure your line-of-sight goes through the upper, distance correction area, of your bifocals.
