Good frame, durable. The glasses fog up relatively easily, but if you clean them, it's okay! For their price, they are fine.

They break easily at the point where they connect, the screws constantly come loose, and the -poor quality- lenses always get cloudy in both pairs.

I would prefer them with slightly larger "glasses". I thought they would be useful for the computer, but they weren't as convenient there, my eyes would hurt after a while. But for reading and small tasks, they are good. I will try to find ones with larger glasses because I believe they will be more comfortable and relaxing. Besides, I don't think there is any reason aesthetically not to get them larger since you won't wear them on the street, but only for reading and small tasks as I mentioned.

I bought 2 pairs of +2.00 & +2.50. The main criterion I chose the E191 was the quality of the plastic. From the photo, I considered that the frame is not made of very hard plastic. Hard plastic makes the frame fragile, especially around the lenses. Now that I have them in my hands, I confirm it. The arms have metal screws and metal springs to have elasticity. The bridge distance is not indicated on the frame but is indicated on the accompanying card and is usually 62mm. They fit well and are lightweight. The lenses do not show distortions. The fit on the nose could be better. A more open curve would make the frame fit on a larger surface, making them more comfortable. For €7, I think it is an excellent choice

Clearly worth their money.
A useful backup set of glasses (for when you have forgotten your main ones and for limited use).
Although very good, I clarify that in no case can they replace quality glasses with quality lenses.
