I mainly use them while working in the workshop and I was pleasantly surprised by their comfort. I often wear them on my nose for several hours and feel no discomfort or pressure. I also appreciate that there is no need to keep adjusting them. At this price, it's really a good purchase.

The glasses are very comfortable. They fit well on the head, don’t slip during movement, and remain comfortable even after prolonged use. The tint is appropriate, and they look ordinary, not like typical protective work glasses. I am really satisfied with them.

They are lightweight, comfortable and fit well to the head. They do not cause pressure even with prolonged use, and their appearance is quite attractive for safety glasses. The lenses are clear, do not distort the image, and provide great wearing comfort. At this price, it's really an excellent choice.

I bought this model for everyday use, needed simple but reliable glasses. The transparent frame looks tidy, without unnecessary aggression, and suits any outfit. The tinted lenses protect well from bright sunlight and my eyes don’t get tired in them, even after several hours of driving or walking outdoors. The plastic is strong, the assembly is high-quality—nothing creaks. They sit securely and do not fall off when bending over. Good, utilitarian glasses for a reasonable price.
