I'm very disappointed!
I was on like a 20 day streak (1 day before 3 weeks, my big goal) and then I lost it : ( on my birthday too, which was yesterday. (I forgot to do it on the weekend, until like 5 minutes before I went to bed.) Not only that, but I found out I'll only be able to do Duolingo 4 days a week, so I'll never get a streak! So when you see me with a 0 day streak, please don't think I'm not committed, because I'm trying. But in the midst of this I'm trying to remember to be thankful, because others may have to try to learn it on paper or books, which isn't nearly as fun. Thank you all for reading, I just had to let y'all know. : )
Well, light itself is technically radiation, even the light coming from the sun. It's unlikely your monitor had anything to do with you needing glasses. There are no credible studies linking computer monitors or other screens with eye damage. I have perfect eyesight and I stare at a computer monitor for at least 12 hours a day for the past 20 years.
