Finding the right vision correction for mountain biking can be tough. Glasses fog up, contacts dry out, and trying to wear glasses under goggles is a nightmare. I needed a better answer. That’s why I decided to try prescription goggle inserts for mtb from Cinily Co Uk. I've been using them for three months now, through all kinds of trails and weather. Here's my day-by-day breakdown of how they performed.
The package arrived promptly. Inside, I found the prescription inserts. I ordered the "Wide-View Square Shield" lens type with a polarized finish, similar to what you’d find in high-quality sports sunglasses. The inserts felt sturdy but light. They looked exactly like the picture online.
My first task was to fit them into my mountain bike goggles. Cinily Co Uk has a great system where you can get just the lens help, even if you provide the frames or, in my case, need inserts for your specific goggle model. I had sent them my goggle’s measurements during the order process, and they seemed to have nailed it. The inserts clipped into my existing goggle frame easily. There was no wobbling. They sat close to my face but didn't touch my eyelashes. The field of view was fantastic; the "Wide-View" claim was real. No distortion, just clear, sharp vision right away. I was pretty happy with this first look.

Verdict: The inserts arrived well-made and fit my goggles perfectly. Setting them up was simple.
My first week with the Cinily inserts involved several short rides on local trails. This was the 'getting used to them' phase. At first, I was a bit worried about how they would feel during a bumpy ride. Would they shift? Would they fog up more than usual?
Here’s what I found:
There was a slight learning curve, mainly just adjusting my perception that I was now seeing through two layers of lenses (the insert and the goggle lens). But this quickly became natural. The folks at CINILY UK US clearly know their stuff when it comes to optical quality.
Verdict: They felt natural and performed well, especially with glare reduction. No issues with movement or increased fogging.
After a month, these inserts became part of my mountain biking routine. I was riding 2-3 times a week, hitting various trails from technical climbs to fast descents. The initial concerns about durability started to fade as they held up to real-world use.
