now we talked about already how the lens inside our eye goes from focusing at distance to then we squeeze the muscles the lens actually rounds up and allows us to focus it near some people's Optical system of their eye is actually wired uh or designed or sort of set up in length not for regular distance which would be anywhere from about 3 feet to Infinity but it's actually designed it's actually tuned for being beyond Infinity which doesn't make any actual sense when you talk about it but just the Optics of the eye at their best Focus are actually focusing the light behind the retina and and if you're doing that when you're younger you're actually using some of your focusing power to to to use those muscles strain those muscles relax that lens round up that lens and have your vision Focus From Beyond Infinity to normal distance like distance vision and so if you're a late and hyperope you are constantly using those muscles and again if you're tired it's the end of the day your muscles are feeling a little fatigued uh your latent hyperopia or by the way if you've had a drinker too uh alcohol can do this too your latent hyperopia can kind of kick in especially as we're aged and we're not as good at refocusing that lens anyway
