I'm 16yo male and for the past couple years every few months I get large blind spots in my eyes making it almost impossible to read anything without words disappearing as I read. I also sometimes completely lose peripheral vision on one side and often comes with a mild headache. When not acting up I have near perfect vision and I do not wear glasses or contacts. I have not had the chance to see an optometrist while its happening because of how infrequently it happens. Is this something to worry about? Is it worth it to go see an optometrist about it even if my vision is perfect at the time?
