The Craftsman Long Life LED/Lighted Safety Glasses work well enough for me to have the lenses replaced with prescription windows. The cost will be well worth it as my eyes are old, but my desire to complete projects safely and accurately remains fresh. Battery replacement is a breeze and inexpensive, especially as they last longer than I would expect. The frames have proven sturdy and durable. They fit me well, but I often use a strap to make sure they don't slide when I'm sweaty or upside down.
Like another reviewer, after about the 3rd time using these one of the LEDs would no longer turn off. Instead it would just go to a dimmer setting when the switch was turned to off. Although I thought these glasses were very handy and useful, I cannot recommend them due to the lack of quality control.
worked great the first few times, then the light part broke. one of the sides wouldnt turn off. i had to remove the battery. so now to use it, i have to install the battery for each use, as apposed to just using the on/off switch.
