ive not been able to find this anywhere but i see you doing it with your glasses on. So this is ok? doing the exercise with your glasses on? i was doing it without my glasses but i found it slightly difficult getting the last bead to split so to say - i have managed to get the last bead to get that v showing 2 yellow bead and 2 green bead but doing it wit my glasses has been much easier and quicker. also i thought that max time was 5 mins? ive actually been doing the exercise for 6-9 minutes (3mins per bead) is this bad??
