Can shining of the phone flashlight be detrimental to my retina?

Hello doctor,

Nine months ago, I used my phone flashlight to check my pupils in the mirror. I had the light extremely close to my eyes and was checking my pupils due to other issues I was experiencing. After I did this, every light source I saw was extremely different. Beams were coming down from every corner, all traffic lights were no longer circular, they were like starbursts. All car headlights were extremely bright now and the light was no longer flat in my view. This went up and down, like up towards the sky and then it fades off. When this happened, my eyes were blurry and burning. Now they no longer burn but I still experience the same thing. I have seen a retina specialist and a cornea specialist, both have said nothing is wrong. I am extremely frustrated because I know something is wrong. When I go to a bathroom, beams of light shine into the mirror. The best way to describe it is to picture a laser tag room but this happens from every light source that comes across. Please help. What could this be? Will it go away or get better over time? I am so confused as to what I have done. What I see is not normal.
