The Fantasea Line 46mm PinkEye Filter M46 is a color correction filter with a 46mm thread. It fits over an underwater housing's lens port and can be installed and removed during the course of the dive. The PinkEye Filter restores the pink color absorbed by green water and enables the production of vivid and colorful underwater images and videos. In shallow depths, this filter can serve as an attractive alternative to artificial light sources. It can be mounted on 46mm threaded lens ports or on other lens ports by using an adapter.
