The amount of people being prescribed glasses is growing each year due to phone and computer use. I have poorer vision in low light conditions then when I was younger. My optometrist has confirmed my sensitive eyes and advised to wear blue light filters but I choose not to. I have friends who need glasses to drive legally at night for similar reasons. Don't give people the wrong impression without first asking professional advice as you could do harm by misleading someone.

While it is true that incidences of myopia are increasing, we don't quite have the evidence to assert that it is due to phone and computer use. Indeed, many studies suggest that the reason might actually be a lack of bright light (i.e. sunlight) and that deliberate exposure to bright light may actually be a good intervention to prevent myopia (see e.g. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0110906 https://journals.plos.org/plosone/article?id=10.1371/journal..., https://www.nature.com/articles/s41598-018-26635-7 https://www.nature.com/articles/s41598-018-26635-7, https://iovs.arvojournals.org/article.aspx?articleid=2355431 https://iovs.arvojournals.org/article.aspx?articleid=2355431)

    From what I remember when I last looked into it: We underestimate how bright sunlight is. Screens just aren't bright enough. They only appear to be bright to us because they are one of the few light sources in indoor environments.

> The amount of people being prescribed glasses is growing each year due to phone and computer use. I have some hope the use of VR gear might start to reverse that trend. The focal plane is normally set a couple meters away from you -- I think six meters for the Quest. Anecdotally, I find it comfortable to look into; it has a 'night' mode that reddens the light, too. I don't know how provable it is, but I've always heard that nearsightedness may be caused by looking at things that are too close, too often. Right now there's a concern in that the focal plane is always six meters, but light-field displays will be coming at some point, probably before these become a mass-market product.

  Word, that sort of claim begs for an associated reference to a study.
