Donegan Optical OptiSIGHT Magnifying Visor-Purple, Other, Multicoloured

They work fine but the additional rubber strap is too small if you have a slightly larger head but it stays on OK without it anyway

very nice for the price. did the job very well.

The all plastic construction and reduced material makes it lighter, easier to wear in hot weather, offers minimal obstruction to your regular and peripheral vision and overall lower cost compared to Donegan's flagship OptiVisor Donegan OptiVisor Headband Magnifier 2 1/2X Magnification . Its simply made, which means little can go wrong, easy to clean, easy to adjust visor or headband tensions and the lenses are very easy to interchange and mount. I have no trouble wearing this item on my head for hours on end, unlike the OptiVisor which is worn like a crown and thumbscrewed for comfortable tightness on your skull, you can wear the OptiSight in different positions you find secure and comfortable as it slips on like eyeglasses. I wear it propped like sunglasses atop your head, and pull the lens way down to allow me to see straight ahead easily. Other times where I shift between magnified vision and my unassisted eyes, I wear it like eyeglasses, with the headband resting nearer to the back of my ears. The headband strap is optional for smaller heads or if you like the headband tight, I don't use it. A reason for choosing Donegan over similar looking competition is their reputation for good optics. While glass for optics is preferred, plastic can be as good and weighs less, if _made_ properly. Lenses have to be free of subtle aberrations to prevent eye fatigue or worse, headaches, and it may not be noticeable until you work for hours with cheaper lenses that look OK by initial inspection. If you buy a cheapo magnifier, you'll have to find how good the lenses or the headband construction is by buying it and working with it for hours. For buying an item sight unseen, the Donegan is a better bet because of consistent quality in both lenses and visors across all their models. Lighter acrylic lenses mean a lighter visor, and like eyeglasses, can be worn for longer durations. Donegan uses the beefier Optivisor for its glass lenses with loupe attachment options, or acrylic lenses in the OptiVisor LX, both at higher cost. Optisight ships with 3 lenses, allowing users to optimize magnification for various types of work. Optivisor and LX ship with one choice of lens. As magnification increases, the distance between the lens and the working object decreases, as expected. However, properly made visors must have the same distance between the lens and your eyes; some cheaper models don't and it makes their interchangable lenses blurry and useless. For those who care, Donegan states all its visors are designed and made in USA. One drawback is a stowage pouch for the extra lenses. Without one, its easy to lose them.

These are pretty decent. The color if fun. My 3-y-o wanted a flip-up goggle to play "Ghostbusters" and we're building a mock night-vision scope around these. As a magnifier, they work pretty well. I use magnifying goggles all the time in my work because of my aging eyes. I can tell you that you can do much better for $20, though. These should sell for about $5. They don't have headband padding and the closure is a crummy slotted rubber strap that goes across the flanges on the two back bands. It has a lot of range -- goes from my 3-year-old's small head to my big man's head, but it doesn't fit as nicely as my $7 cheapo black visors (with Velcro closure) that have two flip-down sets of lenses PLUS a loupe. Velcro closure of the bands would be better. Screw-down knob on the head-adjustment bands would be better. The tensioning screws are a plus, though.

Very lightweight. Well balanced and comfortable, they wear very well. I wear glasses and they don’t interfere with them. I can see around the magnified area. One complaint-the adjustment band provided is a couple of inches too short to be useful if you have a large hat size. It was very tight even at the largest setting. However, tension from the frame and its light weight compensate. It wears comfortably without a tension strap, at least for now.

I did NOT receive (3) interchangeable lens plates (3X, 4X and 5X) and I did NOT receive and fitted plastic carrying case, other than the packaging it arrived in. Is that supposed to be the "fitted" case? I didn't have to cut it to get it open (like an electronic gadget) so perhaps that is why the seller calls it a carrying case. Or I didn't receive the right item. I wonder if the "good" reviews received everything they were promised by this seller? This product is okay-- it magnifies my counted cross-stich projects. That's the reason for 2 stars. It DID magnify. That is the PRO. Now for the CONS. -The item is CHEAP, cheap, cheap!!! It is NOT sturdy. The little black rings and knobs fall off frequently with normal use. It should be $5 at MOST. I paid $28.00 (apparently the "purple" is $4.00 more than the black?) -Lens is plastic and kinda blurry. Really not good quality. It is NOT "polished"!!! -Very hard headband. It pinches the side of my head and gives me a headache after about an hour. -Did NOT come with all the stated items.
