Interesting for people who are contra dominant

"Like being left- or right-handed, human beings also have a dominant eye.
As most of us have two eyes, which record slightly different versions of the same image, the brain has to select one of the two, creating a "non-symmetry."
Many more people are right-eyed than left, and the dominant eye has more neural connections to the brain than the weaker one.
Image signals are captured with rods and cones in the eye - the cones being responsible for colour.
The majority of cones, which come in red, green and blue variants, are found in a small spot at the centre of the cornea of the eye known as the fovea. But there is a small hole (about 0.1-0.15 millimetres in diameter) with no blue cones.
In the new study, Ropars and colleague Albert le Floch spotted a major difference between the arrangement of cones between the eyes of dyslexic and non-dyslexic people enrolled in an experiment.
In non-dyslexic people, the blue cone-free spot in one eye - the dominant one, was round and in the other eye unevenly shaped.
In dyslexic people, both eyes have the same, round spot, which translates into neither eye being dominant, they found."

Fovea is in the retina. The cornea is at the front of the eye. Typical Daily Telegraph error!

Interesting, my right eye is only slightly dominant at distances while my left eye is strongly dominant at close range. I'm also left handed, so I'm cross dominant. To make things even slightly more curious, I'm right footed when kicking but my left leg is more dominant when sking. But I'm not dyslexic or maybe that should be byslexic.

Right handed people with left eye dominance have to cover or 'hamper' their dominant left eye as they aim with their right eye.

Paper or electronic targets only require two dimensional vision . So no problem , or no big problem to use the non dominant eye solo .

Trap and Skeet shotgun shooters need 3D vision ideally and those right handed with dominant right eye shoot with both eyes open and enjoy three dimensional visualization of the moving target . They are at a slight advantage over those with the opposite dominant eye.
