It's possible that he may have black eyes instead of brown. The only way you'd be able to know for sure is if you examined his genetics in SimPE. If the dominant eye colour is 12d4f3e1-fdbe-4fe7-ace3-46dd9ff52b51 then he has alien eyes, but if the dominant eye colour is 32dee745-b6ce-419f-9e86-ae93802d2682 then he has brown eyes. Because only aliens are supposed to have alien coloured eyes, if the alien eye colour is used on anything other than an alien or mannequin, they won't show up properly. Instead the brown eye colour will show up on normal Sims, and a pale brownish grey eye colour will show up on mannequins.
