Thanks to Karen who recommended Promethease on my genetics post. I ran myself and got some fun results. Well, this one isn't so fun- I have a rare genotype, Rs12536657(A;A), associated with hypermyopia. Indeed, myopia and retinal detachment issues are common in my family. I thankfully seem to have halted my vision decline around the time I improved my diet, but that could just be vision stablization associated with age.
