But since different lens brands have different distribution patterns, they may work differently for different people.
The ones I tried today are great for long and mid range vision but not so god for short range, I had some trouble reading. The previous ones were great for reading but I couldn't see my computer screen very well when working  |
hm, very interesting, thank you for the explanation ! the brain is a fascinating thing. it's quite amazing, if you think of it, that it can make sense of an image it will receive in "stripes" or pieces. i hope you manage to find a pattern which will work well for you at all distances. i am just going to count on the presbytie i'll probably suffer from in a few years countering the myopie i currently suffer from. if i get lucky, and it all balances out just right, maybe i won't need glasses at all anymore.
