- ScottBurson 10y agoAt a price, though: high-index plastic has much higher dispersion than the lower-index materials. This causes a greater "prism effect" near the edges of the lens, which interacts very badly with the new RGB-backlight monitors [0].

- jtchang 10y agoMaybe that is why I see yellow all the time on the edges.
- roberthahn 10y agoYeah, I have a pair of those for when I'm not wearing contacts and the chromatic aberration drives me nuts.
- NickNameNick 10y agoI had a bit of that when I got my next-most-recent pair of glasses. It took less than a week before I stopped noticing it entirely. I don't think my current pair have the problem, but I'm not sure I could tell any more.
- roberthahn 10y agoI never got Coke bottle lenses. Those are for people who have no peripheral vision. The Coke bottle design is supposed to bring the peripheral into the area the patient can perceive. What drive me nuts about my glasses is that it effective took my peripheral vision away, making me seem way more clumsy and uncoordinated than I would otherwise have been.
