TenYuaHeadband Glasses Magnifier with LED Light 8X 15X 23X Magnifying Glass for Watchmaker Jewelry Optical Lens Glass Magnifier Loupe

The product is well designed. I loved the LEDs that can be adjusted. The fit was comfortable.But there was one enormous problem: the focal length. You can see nothing literally past your nose with this device. The reason for getting it in my case was to be able to have magnification while using my hands. Since you have to literally hold the object being looked at at the end of your nose it it is not possible to work with this device. The videos adverting the product suggest that the focal length is considerably longer which is a bit misleading.The product I feel could be salvaged with a different material in the lens giving it a longer focal length. The magnification is not great - only 10 fold with a max of 20 - so the lens should be replaceable.Its a great design but with the current lens system it is pretty useless unless you want to inspect things at the end of your nose with a 10x magnification. There are handheld lens that will give you that much magnification and are much more user friendly.Until the focal length problem is fixed I cannot recommend this device.

Even if you take the detachable magnifiers off the standard lens on the glasses is a little too much for what i do. I do electronics and a lot of soldering. It's a little sketchy getting my face too close to a electronic board to solder.

You get what you pay for
