About

We were inspired by the characteristics of eagle eyesight when creating the Degrees of Interest system as a tool for evidence and case data investigation.

• Visual Acuity—Eagles can see clearly from a distance of 20 feet what a human with normal vision can only see at 5 or 4 feet. This exceptional vision allows them to hunt tiny prey from hundreds of feet in the air.
• Color Vision—Eagles see a wider range of colors than humans. They can perceive ultraviolet (UV) light, which helps them spot traces left by prey.
• Field of Vision—Eagles have a wider field of vision than humans, with a binocular field of around 180-200 degrees, compared to humans’ 180 degrees.
• Depth Perception—Eagles’ eyes, with their overlapping fields of view, provide binocular vision and stereopsis, allowing them to perceive depth and distance accurately.
• Eye Movement—Eagles have a third eyelid (nictitating membrane) that sweeps across their eye like a windshield wiper, keeping debris from entering the sensitive tissue.
• Hunting Advantage—Detecting prey from great distances, tracking movement, and pinpointing small targets.
