Fairbssays...How do they know what prescription to wrap on this little rodent?
deathcowI think they approximate it by measuring the shape of the everything by shining light through. The shape of the cornea, lens, and retina and how projections through it render on the retina.

LiquidDriftsays...That is a super cute video!
Kind of weird how the sign in the background is perfectly framed though. Damn my cynical video watching filter!!
antI think you need a prescription if you think that human is a rodent.

SycraftThere are automatic refraction machines. Most optometrists have them these days and will use them before you go in for a manual refraction. They aren't as accurate as a manual refraction, and can't control for your preference, hence why manual is still done, but it quickly lets them know where to start.
Also, for people who have difficulties communicating, such as a baby, it can get you a pretty good result.
