I had an eye exam last week and opted to have ultra-widefield retinal photos of my eyes taken instead of dilating them. I asked them to email the images to me and they did!
I also had wavefront images taken; this kind of analysis was used in the past for Lasik, but it is now being used with eye glasses too. The image represents a topography of the eye and allows them to construct lenses that compensate for the irregularity.
It turns out that with my old prescription my eye sight was 20/40, but I’ll be back to 20/20 again with my new lenses; no more squinting during planning meetings!
