It can be your limbal ring. Limbal rings are usually more prominent in babies and toddlers, and can contribute to their more adorable gaze. Limbal rings typically begin to fade with age in one's 20s, but some people's limbal rings can last longer, especially for those who have lighter-colored eyes or darker-colored eyes with bluish limbal rings. Limbal rings are a normal phenomenon and have not been found to be associated with any health conditions.
