Near-infrared vision in humans enabled by upconversion contact lenses (sciencedirect.com)
Humans cannot perceive infrared light due to the physical thermodynamic properties of photon-detecting opsins. However, the capability to detect invisible multispectral infrared light with the naked eye is highly desirable.

Cross Views (wordpress.com)
Your camera has the ability to take three dimensional photos. Your screen has the ability to display three dimensional photos. You’ve probably never used either. This isn’t a hidden feature of some new phone hardware release, it’s a feature of your brain. All your brain needs to see in 3D is two pictures, and you can trick your brain into seeing 3D on a flat screen using just your eye muscles. I will teach you how.

The secret behind sharp vision: the benefits of tiny eye movements (medicalxpress.com)
Even when we think we are holding our gaze perfectly still, our eyes make tiny, involuntary movements. While these "fixational eye movements" might seem like they would blur our vision, new research reveals they actually help us see fine details more clearly.

REM Sleep as a Mechanism to Prevent Takeover of the Visual Cortex (2021) (nlm.nih.gov)
Regions of the brain maintain their territory with continuous activity: if activity slows or stops (e.g., because of blindness), the territory tends to be taken over by its neighbors.
