I have needed reading glasses for about 15 years and have a script to for reading from a short distant. I have noticed for a week or so that, when I look at the tv to read any information all the letters and numbers are crystal clear for quite awhile. Just after a short time it goes back to being blurred and I need my glasses. I have had floaters for close to 15 years but only around 10 years for the eye script. Has anyone else had this happen and does it last longer or just go away.
