well, if my eyes would just converge properly i wouldn't even need them. i got another pair, more expensive, frameless, but they are 1.25 and it's so strong it would probably be dangerous for me to wear them driving a car. text is not blurry, it's doubled, slightly right and upwards and my right eye is the one that is weaker, it is *slightly* blurry. it was caused by kidney damage from sucralose and acesulfame-k
