In brief: Autorefractors

Retinoscopy, trial frame refractions, phoropter refractions, basically an eye exam at an optometrist or ophthalmologist office, maybe on an iphone in the future.

In brief: Eye exam

We use an instrument called a phoropter which contains many lenses and can generate many potential pairs of glasses prescriptions.
Sometimes the eyes need drops to get a good check for glasses. An ophthalmologist can help you out.

In brief: By eye doctor

An eye doctor will use a phoropter to rapidly change lenses in front of your eyes to determine your refractive error.
