It contains four different texture types, closeups of each below. Please note that as this is an accessory, you need to add it for each outfit category. It is enabled for all categories currently supported by the game, but doesn't stay on when nude. It is not enabled for random, so you shouldn't get townies generating in them. It comes in a Glasses version and an Earrings version for Teens to Elders, and as an Earrings version for children. Just like my TS3 version, this is a Head Accessory mesh made from the default eyes, which fits over the sim's underlying eyes. (I also decided to go the extra mile and add a children's version, which my TS3 item didn't have.) So use it if you want to, or don't use it if you prefer the other mod, or you can mix & match them if you want a bit of variety. So, at the time I felt there wasn't a point in releasing mine, but having now dusted mine off and added a few extras to make it more versatile and use it myself, thought I'd upload it anyway in case anyone else might find it useful. This is a conversion of my old TS3 '2 Different Colour Eyes' - I actually converted it a year ago but then discovered that someone in Tumblr-land had already made a heterochromia mod for TS4.
