Forgot to mention the cheap magnifying led lamp visor came in. I've not really used it, but seems to work fine. It's very lite weight. I'll report back after I use it for awhile for actul work.
Great question OB so yes they can be used together and the kit comes with a head strap which works fine to replace the "legs" of the visor & allows easy use of your regular glasses or safety glasses with the visor. I had not tried using the visor with my bi focals but have them on over my glasses right now using both with their legs and no strap. I can flip the visor lens up and out of the way easily. Both glass optics remain extremely stabil in use and visor lens can be adjusted with one hand.It appears that they have a nose piece, can they be worn with eye glasses ? I’ve been using opti visors for years, at work on my bench and at home in my shop. Granted mine don’t have the headlight attachment, but the ease of lifting it up to use my regular glasses is a plus for me. I’ve worn bifocals since I got out of grade school.
