Very useful information by readers and writer on the drug I use for the last many many years i.e. Lisinopril I had laser treatment done to both eyes and my left eye is giving problem and that is BLURRED VISION as mentioned by many patient on the board. I am pleased to learn that it causes the blurred vision because I get this problem in the morning when I take the does. By the afternoon my vision is absolutely clear 100%. Thanks to you all who mentioned the problems and its a great help for me as well. Next step is to see GP and discuss with him and explain my condition. Thanks you all.
