As Dr.Swapnil mentioned you are suffering from Uveitis
, an inflammation of the inner parts of the eye and started on anti inflammatory eyedrops.
Your sudden blurring(after your treatment) is due to Homide eye drops which causes dilatation of pupil and ciliary muscle relaxation to reduce your pain. So once this is stopped by your blurring will come down.
Since your problem has recurred ,ask your eye doctor and get the required blood investigations to find out any systemic cause Sometimes this condition happens without any known cause( idiopathic) too where in it is treated symptomatically.
Get well soon.
