What They See

This is the biggest update since launch, and it is timed for World Sight Day on October 8. Ten new vision conditions you can see live through the camera: glaucoma, macular degeneration (dry and wet), retinitis pigmentosa, diabetic retinopathy, keratoconus, presbyopia with an age slider from 40 to 70, floaters, visual snow, night blindness, and a drunk vision mode that shows how alcohol affects sight. Five animals join the animal section: deer, shark, octopus, fly, and spider. Deer vision arrives just in time for hunting season; deer are red-green colorblind, so blaze orange looks dull to them. Sharks are colorblind as well, with eyes built for dim water. Octopuses cannot see color either, but they can see polarized light. Flies see through a honeycomb of 4,000 lenses. Spiders have a razor-sharp center with a motion-sensing surround. Floaters drift slowly and react to your phone's motion, lagging behind like real floaters. Tool strips now page with arrows, so new filters are easy to find. Photo import: pick any photo from your library, apply any filter, and save the result. Nearsighted blur is more accurate at higher prescriptions now, based on feedback from optometrists and users. Achromatopsia now includes the reduced sharpness and light sensitivity that come with it. Every new condition has its own deep dive page covering what it looks like, how it works, and what helps. Thanks to everyone who sent in feature requests through the in-app form. Several of these came straight from you.
