Wearing glasses while looking through your camera's viewfinder has always been a challenge, but this Glasses HoodEYE Eyecup from Hoodman more than meets the challenge. This oversized eyecup accommodates HoodEYE use with glasses and links your eye to the camera for improved viewfinder optics. A unique self-locking mount system keeps the HoodEYE eyecup securely in place, and the eyecup rotates to accommodate both right- and left-eyed shooters. It fits any of the Hoodman Eyecups, which (between the 5 models) fit all Canon and Nikon digital SLR cameras.  One of the 5 HoodEYE Eyecups (not included) is required to use this Glasses HoodEYE eyecup.
