###Human: I am using laptop for a long time. Could it be the cause for my blurred vision? ###Assistant: Hello. I understand your concerns. The symptoms you are suffering from are most suggestive of dry eye disease. It is quite common in computer users. The best initial treatment for this is firstly to blink your eyes more often and second the thing is the use of lubricants such as 0.5 % Carboxymethylcellulose acetate eyedrops (refresh tears eyedrops). With this, I am confident that you will improve. In case you have already been taking these measures, or if you have any further questions, please let me know. I will do my best to help you.
