i bought a pair of oakleys this summer. Every time i put them on, the back of my head would swell up and give me massive pain. i thought they where to tight, so left them on the side never to be worn again.
forgot all about it.
went to see avatar in 3D. again same problem. so i turned the glassed round and looked through them and the same problem!! these 2 lumps on the back of my head massive pain.
i have eye tests every 6-7 months and always pass 20-20 vision
any thoughts.
