The word 见到 is formed by combining two individual characters, each contributing its core meaning to create a new, specific concept. The first character, 见 (jiàn), carries the fundamental idea of "to see" or "to perceive visually". The second character, 到 (dào), fundamentally means "to arrive" or "to reach". When paired together, their meanings fuse not as a sequence but as a single idea: the act of seeing is brought to a point of completion or successful contact, thus forming the compound meaning "to catch sight of", "to meet", or "to have seen (and made contact with)".
