hello, ive been experiencing in the past 4 months blotchy areas in my vision that appear when i tilt my head from side to side, its mostly noticeable in the upper inside corners of my eyesight and the outer periphal vision.Almost like there is pressure being applied.It hasnt caused any vision loss. Its gotten slowly worse and was wondering if this is due to accessive eye strain from computer use or if it could be my new glasses.
