Eyes, like I said no screens, and increase Vitamin A intake, more carrots and fish in your case. Other then that rest your eyes and blurry eyes can be caused by low sugar levels, low blood pressure, etc. Do not only focus on eye sight being related to eyes.
But yes if it continues with increased diet, go n get ur eyes checked.
Improve calorie intake, rest eyes, make sure to take enough iftar, and then tell me what is up with ur eyes exactly. is it periodic or continuous, does it go away after food, is it something that happens when u get up from sajood.
