Thanks Mark. Do you have convergence insufficiency and does your work entail a lot of reading? I wonder if that can explain the difference in recovery time between us. I do not jump back to work, I actually take a long leave but perhaps the long impact is due to my eye condition and the fact that my work is = reading + writing ....

Anyone else can relate to that story? Have you come across any PCS saying that watching movies on place made them much worse? The trick is that it happens with a lag, so there is no real time signal/warning that you are overdoing it...

Thanks
