OPC Extreme San Salvo Sunglasses with Polarisation - Matt Black/Blue Revo

The glasses are extremely comfortable and interesting. They work great when driving in cloudy and rainy weather, as well as at night. The polarisation works very well. I definitely recommend them.

Extremely comfortable and, importantly, durable – only the first minor scratch appeared after more than a year of daily use. So far, this has been the best choice among all the glasses I have purchased. The set also includes a very practical case.

Very good quality glasses – comfortable and come with all required certificates. Ideal for those considering a purchase – highly recommended.

These glasses are fantastic – they do not darken the image but eliminate glare and do not dazzle with light. They do not cause reflections and are great for driving, cycling, and the shooting range. The warm yellow tint clearly enriches the view. In cloudy weather it is even brighter, the image is more contrasted and sharper. They also work brilliantly indoors. Unlike sunglasses, you don’t need to take these off. I definitely recommend them, very good product.

These glasses are worth their price – they work excellently. Very comfortable and well made, they fit the face perfectly and don't slip down the nose. The lenses darken perfectly, and the polarisation is a big advantage. They are great both for trips and for driving. Additionally, a durable case is included, which I consider a big plus. I definitely recommend them.

Advantages: - Very comfortable for both cycling and driving - Very good visibility despite strong sunlight - Very flexible - Stay in place well when cycling - Thanks to the design, they provide a wide field of vision - Subtle darkening and effective protection from polarisation and UV filter Disadvantages: - They scratch easily when mountain biking - After a year of use, the frames broke (even though they’re flexible), maybe there was a manufacturing defect - The case doesn’t have internal protection for the zipper, which may scratch the glasses without an extra cloth, so it’s not practical for everyday use - At this price, the glasses could be more durable

Detailed opinion: 1. Lenses: polarisation works correctly 2. Frames: look more massive in pictures, in reality they are not too thick; not a premium product, but better than cheap Chinese goods 3. Size: lenses about 13.5 cm wide, frames 15 cm – good for petite people, but too small for me and limit visibility; not suitable for driving a car or bike 4. Set includes pouch, cleaning cloth, and semi-hard case (won't withstand sitting on it) – a plus 5. Price: on promotion below 150 PLN, for a Polish product the quality/price ratio is OK Would I buy again: no, they're too small.

The glasses look great and have effective polarization, which makes walking and driving on sunny days very comfortable. They also work excellently at the shooting range. I definitely recommend them.

At this price, you can buy without hesitation. The glasses are light, don’t pinch the nose, and are simple. The set includes a case and a pouch. They're not too dark, which for me is an advantage.

The frames are fine, nothing particularly exciting, but I have no complaints either. A plus is the sturdy case and the delicate design, and the lenses themselves effectively protect and improve sharpness of vision on sunny days. The smartcare technology works well, as even with frequent use there are no signs of wear.

OPC brand glasses are a very high-class product. The polarisation makes a big difference. I bought them for my brother, who normally doesn't use sunglasses, but after trying mine he wanted the same, and now uses them every day. I used this model myself for a while and I find that they protect the eyes very well from the sides and are extremely comfortable – even after wearing them for a long time there’s no pain behind the ears. I recommend them.

The glasses work great – they sit perfectly on the nose thanks to the adjustable nosepiece with an internal wire, which allows you to fit them to different nose shapes and prevents them from sliding down to the cheeks.

The glasses were bought as a gift, used mainly for driving, especially when lighting conditions are poor. The person using them is so far very pleased.

Very good glasses. I used them this summer and autumn. The lenses and filter were well chosen. They offer effective protection from bright sunlight, but they're not too dark. I also bought a strap for them, which works well for various activities. The price is attractive. I recommend them.

These glasses are on par with other models in this class and price range. Without the manufacturer's logo you could mistake them for Arctica brand. The polarisation works very well and the tint is Cat.3. Lightweight, flexible frames – although they are a bit narrow, their flexibility compensates for it. However, people with a very broad head should take note of this.
