Floater, Sparkle, Afterimages.

I have a lazy left eye and have power in both eyes. 8 have floaters too in both eyes. There are many web like, tail like, bubble and dot like. For 20 days I have been seeing afterimages of objects like grills, clock, text and images on phone, laptop and tv. Sometimes in Sky I see sparkle glitters like jugnus too many. Sometimes persistent afterimages for the bulb for 3-4 mins if I close my eyes it becomes multiple. Today I noticed a little bit of a light sensitivity also. I got a dilated retina exam at Shroff eye centre 3 days ago and my retina is fine. The doctor is saying the afterimage phenomenon is normal. This did not exist 20 days ago How is it normal? I worked in IT, I am using refreshed tears eye drops. Also, I start to feel tiredness, little pain and burning sensation in my eyes very soon while working on my phone and laptop. Can anyone tell me what to do? Lazy eye, floater now afterimages/ghost images, sparkle, light sensitivity. Shall I consult neuro or other opthomologist?
