i have a dicces called ocular albanism and its not nothing to big but it makes my eyes shake i never notice it but other people do i laugh about it but my vision is 20/80 and it happens to 1 in 60 000 babies and me and my sister have but are parents dont have it so i think we are adopted but they dont admit but thats my biggest thing in my life ... sad life haha
you parents dont need to have it. Both parents may be carriers of the gene for your ocular albanism, which means their children have a 100% chance of getting the problem which is why both of you have it. I doubt you're adopted :P
