After finding out I needed prescription glasses, I wanted to find a pair that were practical, stylish and unique. The blackcap frames fit the bill. It was important to me to find glasses that I could guarantee were sustainably produced and I was assured of that with Bird. Working in forestry it was an extra bonus to get a pair that I can say are made of beech and bamboo. I had to adjust the glasses slightly when they arrived to hook around the ears and head more but I was guided through the process on the online chat and got the fit perfected. I have had so many people compliment the glasses since I started wearing them, people seem to love wooden frames as much as me!
