FRAZALAPolarized Clip-on Sunglasses Anti-Glare Driving Glasses for Prescription Glasses

I bought these Fish Man's clip-ons-for-eyeglasses to help my wife with night driving. They are supposed to block horizontally polarized light and filter out blue light. They do these things, but not very much, maybe a perceived ten to twenty percent effect at most (the eye actually has a logarithmic response).I ran two performance tests of the clip-ons versus my existing amber polarized sunglasses. The first test was with polarized filters and a polarization-check test image and the second test was in the field staring at oncoming car headlight while parked on the shoulder of an arterial.The first test strongly suggests that the clip-ons are, at most, only ten to twenty percent polarized (by eye, logarithmic response, remember). They also seem to provide a similar reduction in blue light (which is the most annoying part of glare). Note that typical polarized sunglasses provide a 99+ percent reduction in horizontally polarized light. The filter strips in the attached images are completely polarized in the short direction (just like polarized sunglasses).The first three images are of the clip-ons and the last two are with my existing amber polarized sunglasses for comparison (the very last image was taken with the sunglasses right up onto the camera lens - the colors in the image suggest circular polarization - interesting but of no consequence to this review).In the night glare test, my existing amber polarized sunglasses performed far better at reducing glare, but they did that in good part simply by reducing overall light. Interestingly, for reducing headlight glare in the field, by itself, the vertically polarized filter strip seemed to be no more effective than the clip-ons (probably because the overall transmitted light level was still too high).I suspect the goal for night vision lenses is to not reduce too much of the total light while filtering out as much glare as possible. For city driving with lots of traffic, bright street lamps and high overall ambient light levels, clear, amber, not-too-aggressive polarized sunglasses might be a better choice (assuming your issued is glare and not poor night vision). These clip-ons seem to be of overall high-quality construction, but I do wish the designers had chosen to filter out more light since good clip-ons like these can quickly be flipped up and down like a light switch as needed.Bottom line, these clip-ons are a good quality-built product that filters glare - just maybe not enough to be truly useful for most users.

I spent a lot of time looking for fit-over sunglasses and could find none that were big enough to go over my new frames. So I went to clip-ons, saw these and the many good reviews. They fit very well and I'm very pleased. The sunglasses are fine but I was particularly wondering about the night-driving lenses. I have become increasingly annoyed at night by approaching high intensity headlights that are more and more common. I've only had these for a couple of night driving experiences. They are not magic and I really didn't expect them to be. But they cut the high intensities enough so that I don't always have to look to the side of the road as the cars go by. I'm very happy, particularly since they are easier to use than the old fit-overs I used which were bulky and hard to keep handy.

I got the YELLOW AND GOLD. After reading some reviews I decided to try these due to my freak accident that detached/tore my retina in my right eye. When my vision was in question I really woke up to that whole issue. The eyes are so so important and delicate that any protection you can give them is just common sense. Then you add that to the fact that these lenses are so reasonably priced and you have a must have item times 2. I just got them and cleaned them all up. I placed them on two different pair of glasses for faster use. If they are already on then I will not forget about putting them on the frames. The daily protection of my valuable eyesight is a no brainer. Reducing the strain and glare of everything you look at is a good way to help keep your vision in good shape. Why not do something positive for your two important eye balls. You only get one set of eyes, When I lost my vision for a couple of days in one eye I really thought about how the other could go out at any time as well. I got a deal on mine, money well spent.The 200 plus other reviews informed me that these are not junk with no value. I would still use a larger protective set of glasses or goggles for doing the lawn and edging. Side protection is a good idea.

These are very nice clip ons and the fact they flip up when you want them to even better. The yellow polarized lenses are great for adding contrast to the night driving and rainy days and they do reduce the glare of oncoming cars. People who drive at night with early stages of cataracts would see benefits from these lenses (not a cure for the problem but it helps). The Polaroid sunglasses are also very nice, I have the orange color and they are plenty dark for a sunny day. You have to be creative and patient about getting them on in the most comfortable way since they are generic but wow they work well and I really like mine. You can not beat the price. This is a good deal and so much better than glasses over glasses for night vision.

I have owned a number of clip ons. What makes these great is that they attach at the bridge instead of the sides. I live in Seattle and when the sun comes out we are wimps. These are great because they are flip. When driving and need to go to underground parking they flip up and don't need to use two hands. Great design and price. Well work it in my opinion.

If you're wearing low-profile or slim lens eyeglasses, the only clip-on shades that will fit are those with short clamp arms, as this eye shade has. Clip-on sunglasses with long clamp arms will interfere with the nose pads on your eyeglasses. These sunglasses come with an impressive case. I will be wearing these on a trip to LA next Monday, driving home at night. If all goes well, I will up the rating to 5 stars. UPDATE 7-24-2019: I wore these clip-on sunglasses (Yellow) driving home from LA on a one-lane highway thru the California and Arizona desert after sundown. These shades were wonderful for reducing the glare from oncoming cars as long as the oncoming driver wasn't using his brights. For those few cars using brights, you need to flash them quick, and still look away at the right side of the road. But these clip-on shades made my night trip much easier than it's ever been. "Don't leave home without them."
