Dry eyes with fogginess and loss offocus

I have dry eyes and most of the time I experience blurry vision I have been prescribed a -ve power of 2.5 with cylindrical axis. I am not able to get what we called a perfect vision using cylindrical glasses. My eyes feel heavy also like shooting lazer in the eye most of the time. I have used Hylasoft/Systane Ultra/Opsion Ha/Optisoft/Optive/Zonasoft but Only Opsian Ha and Zonasoft appeared to be ok on my eyes. As now Opsian Ha is not in the market I am using Zonasoft for dry eyes. I literally not sure what to go for as I only felt ok with these 2 (Zonasoft and Opsian HA) but they are very temporary. Bluriness still occurs when I work or do nothing after few minutes. Please suggest is Zonasoft fine to use. Also, I want to know how to overcome the keeping of eye straight and wide open as Almost half of the eye remain down whenever I work or look at something it doesnt appear to be a problem but I feel Anxiety to look straight as I feel eyes out of focus in a wide area  or even in closed
