Both sildenafil and you may vardenafil bring inhibition from PDE-6 isolated on retina, resulting in problem from light import owing to bravery reaction. Sight problems was limited and never well documented which have tadalafil due in order to the specificity out of PDE-5 isozyme more PDE-six isozyme (>700 minutes). 17,18
