If you're seeing annoying color effects it could also be the anti-reflective coating that is bad. Or just that you're not used to having it.
There are alternatives to the phoropter exam called autorefractors and wavefront sensors which use lasers to measure your eye. I'm pretty sure the UK must have clinics who use them. Startup companies in the US are trying to make "kiosks" for eye exams based on such technologies, but run into state laws that restricts prescribing lenses to licensed optometrists. Also there are startups trying to scale such technologies for the developing world where they don't have sufficient eyecare so people with bad refractive errors are basically just left blind.
- dan-robertson 7y agoIt’s true that these exist but they are rare and not typically advertised. Studies have also shown that one doesn’t necessarily get better outcomes from the kind of objective refractometry that an autorefractor gives (because eyesight is a combination of the optical properties of the eye and things happening in the brain/optical nerves)
