Make motorcycle helmet reading glasses

I've taken apart a pair of cheap reading glasses. I can see very well far away but I have a hard time reading my smartphone without glasses and even the dashboard with little light. On the road my viewing angle is always above the reading glasses and when off the motorcycle all functions of my modular helmet remain the same. I can also still use the built in sun shield without a problem! It doesn't win a beauty prize but it is really handy and cheap to make, just one 5g pack of sugru.
