Launch HN: Quadrant Eye (YC W21) – Tackling online eye exams and at-home eyecare
This is really neat!<p>A few questions after trying the prototype:<p>(1) Is there enough variation in people&#x27;s arm lengths that it would be beneficial to give another way to describe the distance to the monitor?<p>(2) Is there any impact from the monitor&#x27;s dot pitch or contrast settings on which lines people will be able to read, even at a constant size and distance? Are some monitors effectively just better quality in a way that could lead to a different result?<p>(3) Is there any impact from the monitor&#x27;s physical aspect ratio because some people are looking more straight ahead and some are looking more to one side (when using a wide-screen monitor in landscape mode)?<p>(4) How well can people who have double vision or retina problems correctly match the test images they see to one of the intentionally-distorted samples?  Could their vision problems also distort the samples so that they end up picking the wrong one?<p>(5) Could having the intentionally-distorted samples visible at the same time as the test image bias people&#x27;s perceptions, since they can guess which one is most normal (least distorted) and then optimistically claim to have seen that one?<p>(6) Will you be able to realistically simulate the effects of a proposed prescription change, even without having physical lenses for the user to look through? (I didn&#x27;t upload my prescription to the prototype, so I don&#x27;t know exactly what happens after that step.)
