I typically go mountain biking or travelling and these glasses are great for all conditions

I purchased the Rockbros Light Weight Full Frame Photochromic Sunglasses as I haven’t upgraded glasses for many many years. I was concerned that these may look overly large on my face but am very happy. They fit well and stay in place. The photochromatic works seamlessly and as yet I haven’t noticed the transition negatively at all. I have also used the prescription glasses option that I haven’t done before and it fits and works perfectly - and I can see! It would be great if it could be a larger insert to take advantage of the beautiful large view but I am still really happy. Highly recommend these budget minded glasses that seem way more expensive that what I paid.

So far so good.

Yes, they are ok...Just.
Pretty cheap make, like, say, a $10 pair of sunnies from a Servo, and the photochromatic ability only just works, as in, they change from clear to a teeny tiny bit darker when you are in full sunlight. So I guess that explains why they are so cheap to buy!
You get what you pay for.

High quality product and it looks great. Delivered on time.
