@ Don....I wear a Hawk modular as my full helmet - I have the same problem with glasses, but with the Modular, I put the helmet on, lift the chin bar, put the glasses on, and lower the chin bar...good to go.
@ Stig....you are of course correct, Sir, and I bought the Full face modular with the intent of not ever wearing the 3/4 again. However, with 3 fused back vertabra and limited ability to turn my neck, I have opted for having better visibility when riding in the city. On the highway, I can make due better with the decrease in peripheral vision.
I also do a lot of bicycle riding. Anyone else feel that the itty, bitty bike helmets leave you feeling unprotected... Almost want to wear my 3/4 wen riding the bike as I can hit 30+ going down hills with no problem....LOL
