Sort of. There's a device called an autorefractor which can get a pretty good estimate out of your refractive error. However traditional eyesight tests tend to provide better results. I believe wavefront guided LASIK uses some kind of automatic method of determining refractive error called an aberrometer. Some ophthalmologists have a device called an i-profiler that they use as part of their assessment which appears to be an aberrometer. Everything I've read on the matter seems to me to indicate that there is possibly some kind of hybrid automated autorefractor/aberrometer type technology that could be created to give fairly objective and accurate measurements of refractive error with no human operator, but given that legally an ophthalmologist would need to sign off the prescription anyway the upside is probably limited.
