A method is discussed for calculating the gravitational lensing of light passing through a wormhole from one universe to another. Fundamental and characteristic features of radiation traveling through a wormhole are identified, allowing new methods for observing wormhole-specific characteristics and yielding techniques for determining the parameters of wormhole models.
