It is better to use 0.5% drops because 1% drops are thicker and can cause blurring while you work...also follow 20-20-20 rule i.e. Take 20 secs of break every 20 mins and look 20ft far and use 0.5% drops twice a day.

Hii.. I am assuming you have been using 0.5% cmc three times a day for some time now.1% is thicker, and has more retention capacity, so you might not need to use it as frequently.
Next Steps
I would suggest you to continue using for three times a day and see if you are feeling better for a longer time period after a single use, then you can reduce the frequency upto two times a day.
