Vision AidMagnifying Glasses with Light for Close Work, Headband Illuminated Hands Free Magnifier with Storage Case for Coins Macular Degeneration Miniatures (requires 3 AAA batteries)

I bought these for my boyfriend's mom because she does a lot of paint by numbers that have small spots she had trouble seeing and this has helped her a lot, she loves it!

The magnifier glasses come in a sturdy black clamshell storage box that has a zipper closure. They fold neatly and securely into this box. The storage box holds yet another plastic snap close box for the five interchangeable lenses. There's a headband that can be snapped in place as an alternative for the temples that are installed as shipped. Also included is a cleaning cloth for the lenses. This storage box is really sturdy and I expect it would provide protection for the magnifiers and lenses even if dropped. I did not test this.The magnifiers themselves are made of a very tough lightweight plastic. Flexible but really sturdy feeling. Metal pins and screws are used everywhere there are joints or moveable parts.Except for adding three AAA batteries I used the magnifiers straight out of the box. The batteries are held in the magnifiers frontspiece that is touching your forehead. There is a battery cover for that clips closed on the inside of the frontspiece so it's simple to install or replace the batteries.I have no idea how long the three AAA batteries would power the LED light on the magnifiers. I used them for about 7-8 hours, almost all of the time I was working with the light on. The batteries do add weight to the magnifiers and if they were being used where there was already good lighting, the batteries could be removed.The light is a dual white LED on top of battery case on the front of the magnifiers. There is an off/on switch for the light. The LED lights are in a little holder can be positively clicked at different angle positions to adjust how the light is shining on what you're looking at. The white LED light is very bright even in a dark room. I think that having two bulbs probably helps with that and helps reduce shadows on the objects you're illuminating.Once I got used to how bright the light was, I felt it was really helpful, especially when working with some smaller photoetch parts. Even though I have two light sources on the workbench where I model, I think I'll always still use the LED light. As you turn your head to focus on your work the light follows and illuminates whatever you're looking at. Very nice!The five magnifier lenses included are 1.0x, 1.5x, 2.0x, 2.5x, 3.5x strengths. They are hard durable plastic and very clear. The lenses snap securely into a holder that is underneath the front of the magnifiers. The lens holder itself can be positioned at different angles including the ability to completely flip the lens up and out of the way.I tried all five of the lenses to do some fine scale modeling work and for the work I was doing the 2.5x was more than adequate. The focal length for my test was about 15 inches from the lenses. For the work that I was doing this was a very comfortable and "natural" distance. The 3.5x strength lens was impressive and could come in handy but I just didn't need that much magnification for what I was doing.As I mentioned there is an optional adjustable headband. To use this just unclip each temple piece and clip in the ends of the headband in the two places where you unclipped the temples. The headband is an elastic adjustable band that was okay but really for the work I was doing the magnifiers temples had quite enough spring to securely hold them. The headband might come in handy if you had to work with your head at some odd angle where the magnifiers might tend to slip?I have a "large" hat size. The magnifiers temples as out of the box were tight. They have a "rubber" pad on the inside end for more "grip". For me this was more than enough for a secure tight feeling but not "pinching". I don't know if the temple's "spring" could be adjusted as I didn't try.The only really adjustable part of fitting the magnifiers to your face is a bendable nose piece. This is how the magnifiers rest on your face. The "blades" of this nose piece can be bent inward and outward to adjust for the width and fit on your nose. There are some silicone covers included that slide over the nose piece blades. I tried the fit with and without these pads. With the silicone covers on I had to spread the nose piece much wider to get the right but it felt better with them. It took a few tries, bending the blades in and out to get it just right. I used the magnifiers a few times before I got them adjusted the way I liked them. Most of the weight of the magnifiers rest on the nose piece so adjusting it to fix comfortably is important. Taking out the batteries would reduce the weight resting on the nose piece, a consideration if you don't need to use the LED light.I used the magnifiers for a few sessions of about two hours of focused work, seated, looking down at a model on my workbench, I thought they would feel heavy or slip, especially where the nose piece rested on the bridge of my nose, but they were comfortable, secure, and did not feel loose at all for that whole time.Lastly about using the magnifiers over prescription glasses. I have "no frame" glasses so this sort of worked but wearing the magnifiers over your glasses means the nose piece can't fit as close to your face. It changes how they fit on your face. It sort of worked but I don't think it would be practical except for really short periods of time. My glasses are mostly for distance anyway so I didn't try to wear them with the magnifiers, other than just to see how it would work. Unless your prescription glasses are really small I don't think the magnifiers would fit comfortably over them.
