YOCTOSUN LED Headband Magnifier, Rechargeable Illuminated Magnifying Visor -1X to 14X Zoom, Hands Free Head Mounted Magnifying Glasses with Lights for Close Work, Sewing, Crafts, Jewelry, Watch Repair

These things are great! I use the 2 highest magnification lenses together, but it is very important to get the lenses lined up for proper focus and also to allow your eyes to superimpose the left/right image to get the 3-D effect.A little optics 101: If you are using 2 lenses in combination It is important the 2 lenses be parallel and overlap each other (you want the centers of each lens aligned) The only way to do this is to make sure both lenses are at 90 degree angles on the sliding mounting bracket in the headset. Start with the lenses aligned and parallel, then slide the mounting bracket as far back as you can to bring the lens in back as close to your eyes as possible. To get the 3D effect working I have to sometime look above/below the lenses, let my eyes adjust to normal vision, then keeping my eyes relaxed, look through the lenses. This is especially important at high magnifications. If you don't get everything right all you get is a headache

I got this to paint my Flames of War Miniatures. Before I had to hold it close and lean into my light to see what I am painting. With this headset, the light alone is super helpful, and the magnification helps SO much. I can ACTUALLY see what I am doing now.I dont know why some people are saying this fits poor, as I was able to adjust its size/tightness and fit very easily.Overall, 11/10

I bought this magnifier out of a desire to have a better way to see splinters that I often get when working on wood and metals in my shop. My illuminated jewelers loupe has more magnifying power, but the splinter-less hand needs to hold it, leaving no available hand to operate the tweezers. So, a head-worn device was required, and LED illumination and adequate magnification was also a MUST.This product also seems ideal for inspecting printed circuit boards and doing soldering of tiny SMD components, and similar tasks. The Stereoscopic view gives the user much better depth perception than a single-lens magnifier.The build quality on this product seems quite good, and I can imagine a professional using it, although hardcore head-worn magnifiers probably incorporate more advanced optics than this device.The headband adjusts over a wide range, using a locking knob on the rear, so it should fit almost any head size.The LED illumination module, which includes three LEDs arranged side by side, swivels sideways and tilts up/down to get the light where it is needed. A button turns the light on/off, and also toggles between two brightness settings. The module can be removed from the headband assembly, and used as a hand-held illuminator. It has an integral rechargeable battery, and it comes with a very short USB-A to micro-USB cable, perhaps 4.5 inches long; the mini-USB end plugs into the module, and you are expected to provide a USB power source such as a computer, power bank, etc; in order to charge the battery. An LED next to the module's on/off/brightness button indicates red for charging and green for charged. Due to the short length of the charging cable, it is best to remove the module from the headband when charging is required, but of course the user can substitute a longer cable. I took a generic USB power supply/charger (wall wart) and assigned it to remain with this device for the purpose of battery charging (one of my photos shows the USB power supply that I use.....THIS IS NOT INCLUDED WITH THIS PRODUCT!)Underneath the illumination module, and in front of the wearer's forehead, are two snap mounts, one in front of the other, and both can be ratcheted forwards and rearwards somewhat. The user selects one or two of the five provided stereo lenses, and their top-center tabs are what plug into the two snap mounts. So, the user can attach one or two lenses, adjust their front-to-rear position, and tilt them somewhat for best effect and optical clarity/focus. If two lenses are attached, the front one can be partially tilted to be out of the line of sight. The selected/installed lenses multiply, so a hypothetical 2x lens and a 1.5x lens would add up to a x3 magnification. The box states that the user can arrange to have magnifications between 1x and 14x, although I have not verified this.There is also a third possible lens, looking like a small magnifying glass, and it can be swung down from its "out of the way" position to be in front of the user's right eye, either by itself or in conjunction with one or two 'normal lenses'; in this instance, the left eye (if open) will see a different magnification than the right eye. Since the five main lenses are 'stereo', they actually each incorporate a left lens and a right lens, and stereoscopic views are obtained, unless the user engages that third small lens.A two-piece plastic box & lid is included for storing the protecting the five stereo lenses, and a small swatch of microfiber cloth is also included to wipe the lenses.The included printed manual is pretty poor, using rough "Chinglish", so the user will have to figure out almost everything through intuition and experimentation.The box that this product comes in is sturdy enough, and the form-fit clear plastic molded support seems reasonably durable, to allow storing the product along with its lens box and the charger & cable all in one place until needed.

I have Macular Degeneration and it helps immensely with close sewing that I do in quilting.

Works as advertised but you had better be a self learner and not need instructions. Simply the worst instructions I've ever come across. Like scrabble tiles dumped on the floor and randomly assembled into a word salad. I can't believe in this day and age you can't find a single Chinese-English bilingual translator. And I don't mean someone that learned English watching cartoons. Might have gotten more stars if you had a functional instruction manual.

I love it! It’s made well, easily adjusted to fit any size head. Interchangeable magnifiers slip on and off easily. Fits perfectly, even with your glasses on.
