you either misunderstand the word opposite or you misunderstood the post. thats exactly what the post is about lol

also its normal to have a headache after starting to use glasses for the first time. i got lucky and didnt have that but its very common. i heard it happens because of how different it feels to look around just with your eyes (not turning your whole head around) when ur not used to glasses. i could be very wrong, i just remember whoever worked at the place i got my glasses from said that i might get a headache unless i move my head everywhere iook
