I have ptosis and astigmatism with some HOAs. When I look at a screen I see blur or tails coming out of it which disappear when I open my lid a little wider. That happen also when I blink. Is that usual? or it is due to ptosis?
Another thing I notice is that if i didn't open my lids wider and kept them as they were by default and with these tails my eyes get tired after about 15 minutes of reading on a screen, but if i opened my lids I could stay for 2 hours without feeling my eyes are tired!
