Spanish is my first language. With in Spanish is Con, without is Sin, so for me it’s easy to remember c and S because its almost like if it was the first letter of the actual word. The same with OD, OU and OS, OD is easy to remember because Right eye in spanish is Ojo Derecho so it starts with O and D, I just single out the U to always both and the only one left for left is OS

Thank God I came across this excellent, clear & didactic youtube channel ! God Bless You !
