Lens — the need to be able to focus something (thoughts, aspirations, desires).
You are studied by colleagues.
A lens symbolizes concentration and visionary clarity. When a lens appears in a dream we need to be clear as to whether it is enlarging the object being looked at, or is intensifying it. Enlarging it suggests taking a wider viewpoint, intensifying it requires that we pay attention to detail. A full interpretation can only be made in the light of other circumstances in the dream. It is the context of the dream that is important. Just as in everyday life a lens helps to focus the attention, so in dreams it can signify our need to perceive something very clearly.
