instruction: hello doctor I began to see streaks of light across my vision in the dark and realized I have a gray shadow in the left peripheral vision of my right eye since yesterday evening I have been spending time on my laptop or phone for more than 10 hours a day and sometimes I watch the screens in the dark I slept for 12 hours and still seem to have the shadow area it disappears if I look directly at it please tell me what to do
output: hello using a computer for a long time causes dry eye syndrome due to decreased blink rate take frequent breaks and look at far objects as the eyes are strained looking at close object for a long time keep the brightness of the system to minimal use tear drops twice a day along with antiglare glasses about the peripheral shadows there is a jelly like substance in the eye called vitreous and as age progresses it starts to liquefy and you start seeing floaters you should go to an ophthalmologist immediately in case if there is an increase in the number of these floaters or if you are seeing flashes of light because these are the signs of retinal detachment get your retina checked once the lockdown is over
