I bought these thinking, "how bad can they be for $10.99?" But I am very pleased. The yellow night vision ones don't do much for me, but then again I don't have problems with night vision when driving. They subdue oncoming lights somewhat, but it doesn't help me enough to get me to put them on. HOWEVER, the dark ones for daytime are fantastic! In addition to minimizing the over-all irritation to eyes from sunlight, they reduce glare tremendously. In a parking garage where sunlight pours in from the sides and everything is in shadows, they made everything much clearer as if a low wattage light had been turned on in the building. On a street with sunlight coming 9n between heavy trees where anyone walking in the shade of those trees would be lost due to the glare, the sunglasses made the people very easy to see. Best of all, I am always annoyed by the reflection back up onto the windshield of objects on my dashboard or the dashboard itself or the air vents on the dashboard. They always interfere with my vision on a sunnt day. These sunglasses totally eliminate all of these reflections from directly in front of the driver to the center of the windshield. I even put a plain white sheet of paper on the dashboard right in front of me, which would have left a huge white reflection in my field of view while driving. With the glasses, the white sheet was totally eliminated. No reflection at all. I once had blue blocker sunglasses and while they did reduce irritation from sunlight they did actually remove all blue light. Everything you looked at was not the color it was supposed to be. These sunglasses do not alter actual colors at all. I love them.

I love these clip on dunglasses. They fit perfectly over my glasses and stay secure. I love the very nice box they arrived in and the bonus of a lens cleaning cloth. I look forward to using these for a long time.

This is the first pair of clip-ons I have purchased, so I wasn't sure what to expect. They seem a little thin and I could possibly brake them easily. I don't have any comparison for a reference though. That aside, they do the job I got them for. They cover my glasses well & don't hinder my field of view. Both the yellow and grey version do a good job. Gray in the sun & yellow in low light/cloudy days.

Nice Fit! Work Well! I have 3 different pair of glasses different shapes and sizes and I can say they fit well in every single one of them. They provide great shade. Really like the pop up feature, So you can use your glasses while not having to take of the shades. overall I can say I would give this item one thumbs up!!

When I picked up my new glasses from the optometrist I asked him about clip on sunglasses. He wanted to sell me a clip-on (but not flip) for $50. I took out my phone and went to the Amazon app and found these for nearly 80% less, AND they are polarized. I ordered them, and I am really happy I did. They clip on firmly and flip up and down easily. And the clarity is exceptional. And to add to this, I am receiving compliments on how cool they look WHILE THEY ARE FLIPPED UP!
