In the last 6 month, 4 time it happened for 5 minute each duration .. when i see sunset like situation (basically see all things in pink color kind of background) Already consulted eye expert, he did all 'relevant test' like eye pressure, eye test, etc. and said it's not a case seen in his entire career. I don't have any problm of bp, thyroid, migrane, etc. He suggested take propr sleep. I trust him as he is a Mbbs with 20 year experience. Still, if i get ANY SECOND opinion here by any other expert, would be appreciable.
