@Bwee@meow.social we're not blind, but we're supposed to wear glasses (we're probably slightly short-sighted, but in such a way that it would cause too much strain to have the same correction to see close and far, so we have progressive lenses. also we see double as soon as our eyes are slightly tired, so the bottom part of the glasses are supposed to help reduce eye fatigue)

in practice our computer screen is constantly at eye level since we rarely use laptops (and if we do, it's typically at work where we have a second screen) so we mostly wear them when we buy groceries or if we bike
