Blurr vision
Sometimes in the class when i used to see the blackboard the handwritten lines are seem to be blurred. Also sometimes tear comes in my eyes but this is rare. But when i rub my eyes, for few seconds it is clearly visible and after that when eyes got blinked it burred again.
You need to get your refraction done. If it is normal then this can be evaporative dry eye where tears evaporate at a fast rate and with lack of roper tears our vision becomes blurred and we rapidly blink and again start seeing clearly
Next Steps
Blink frequently. After evry 20 min of continous activity involving concentration take a break for 20 seconds atleast and look at things atleast 20 feet away. Known as 20-20-20 rule
