"According to the Vision Council of America, approximately 75% of adults use some sort of vision correction. About 64% of them wear eyeglasses, and about 11% wear contact lenses, either exclusively, or with glasses. Over half of all women and about 42% of men wear glasses." Apparently I am not alone and this statistics shows that smartwatches are not suitable for a significant part of population. In other words they will never be as poppular as smartphones. As to bigger screen suggestion, depending on how bad your vision is, you man need such a huge screen to read without glasses it becomes impractical.

>depending on how bad your vision is, you man need such a huge screen [...] Upper limit of the minimum requirement is probably the size of the screen of the phone being used by the individual? Or do many people always use a phone with reading glasses (eg to check the time in a nice big font)? Those stats you've listed don't look so great. They seem to include those who are short-sighted and can read just fine without glasses. (Eg most children to people under about 40 who wear corrective glasses). Somewhere in middle age every single one of us needs reading glasses as our corneas harden. Long sightedness. This is the relevant thing for smart watches & smart phones. Either all of the middle aged to elderly must put on reading glasses to view their smart watch or they don't use one is the status quo. It really looks capable of being disrupted to me in a market that appears to be growing. Especially given the potential for health benefits of smartphone monitoring etc. which is more attractive to middle aged to elderly given the greater prevalence of medical conditions.
