12 years ago, I walked into a second hand eye glasses shop in India and they had one of these machines. It was amazingly effective. I felt duped by all the optometrist appointments asking me about A or B.
- mixmastamyk 5y agoDuped, because they are doing it the old-fashioned way?
- dr_dshiv 5y agoBecause they are making theater to justify their cost.
- comeonseriously 5y agoDid the machine tell you if anything else was wrong with your eyes? Could it?
- dr_dshiv 5y agoIt could determine my index accurately. It couldn’t tell if I had symptomless eye cancer, however.
- fn-mote 5y agoTo me, the tradeoff of an expensive modern machine vs an cheaper iterative process seems logical. I think it's funny that a second hand shop has the fancy equipment... but they must know it sells glasses more effectively. Here, the machine results are used as a starting point, validated by A/B but I don't know if the human part is effective or just theater.
- dr_dshiv 5y agoWell, assuming the optometrist charges around $50 per hour, after 10 patients it would pay for itself. I assume the machine is simply cheaper, which is why it was used.
