Re: Light scatter or something.
I am not sure about the issue above, but I would like to point out one safety issue I have found with prescription glasses. I have some sunglasses which I like to wear when driving. When I wear them the displays are difficult to read. I found, turning my head sideways, that things were almost normal. A very clear case of polarisation and something to be aware of when looking toward getting driving prescription sunglasses with modern digital displays.
