Each person has a different distance between their eye and eyebrow. Some people actually pluck their brows to be farther away.
maintain distance between your eye and and eye piece of the microscope it helps
About 300 yards.

The ratio of the spacing of the fingers and the distance from your eye will be the same as the ratio of the height of the object to its distance from you, so Hf/Df = Ho/Do and Do = HoDf/Hf
The max. distance between the two boys will be 36.6 ft. if they are lying with their faces on the ground. The min. distance between them depends on how tall they are (height of eye). Say height of eye is 5 ft. then the distance between them will be 32.94 ft.
It's roughly 120km from a birds eye point of view, not by road.
The parts of a fish hook are the point, the barb, the shank, the gap (the distance between the point and the shank), and the eye.
healthy eye can see minimum distance of 25 cm and can see up to infinite distance without any tension of eye.
Formula for working out height of a tree is (distance from eye to base of tree/distance from eye to base of stick) x length of stick = tree height.(distance from eye to base of tree/distance from eye to base of stick) x length of stick = tree height is the formula for working out height of a tree.
Between three and four times the diagonal width of the screen (which is the manufacturer's size measurement).
There are different ways to answer this question. The smallest separation observable with the unaided eye is about 0.01mm The smallest observable distance between two points is about 0.4 nm, which is the resolution of the most powerful Scanning Electron Microscope. The smallest theoretical distance between two particles would be the distance between two quarks inside a neutron, which is 10-18 m. The shortest mathematical distance would be 1/infinity.
