Modern Car Headlight Bulbs; Short Lived?

[ppppenguin]

Terry, I think you've worked it out. When you have a cataract done the astigmatism usually remains. THis can be fixed by using a toric intraocular lens instead of the usual lens. Unfortuantely not available on the NHS.

You can have the reading part of a varifocal cranked up a bit for close work but you don't get much field of view. So if your short sightedness allows you to do close work without glasses this is a useful option. The main requirement is that you don't have too much astigmatism.

Varifocals are great but they are not perfect. There's much more distortion of images towards you peripheral vision. Sometimes I drive using a pair of normal distance glasses (rather than the varifocals) and it's lovely having a wide and undistorted field of view. Unfortuantely I can't read a map, can barely read the satnav and the speedo etc are little blurred.
