A dome port is a concentric lens that adds an optical element to the camera lens. When the curvature of the dome's inside radius center is situated as close to the nodal point of the lens as possible, the dome port greatly decreases refraction, radial distortion, axial and chromatic aberrations.

What are the advantages of using a dome port?
Advantages
- The image is not magnified due to the refraction of water, which means you retain the "wideness" of the lens
- Colour and sharpness is better with a wide angle lens, since you can get closer to your subject due to advantage #1
- Water particles are pushed further away from the camera lens allowing for better focus, clarity and sharpness in images
- Less chromatic aberration (colour fringing)
