A physiotherapeutic apparatus for preventing and treating near sighted eye has a convex lens used as objective lens, lens cone, eyepiece, headgear and lens set.
In addition, a sufficient condition of convex fuzzy-valued function getting minimum value is presented, and the method of convexification for a usual fuzzy-valued function is also given.
On the other hand,we use a new method of moving neighborhood to simplify the proof for the continuity of a subconvex function defined on a convex in a normed linear space.
This is made possible through something called a lenticular lens – a corrugated sheet in which each ridge is made up of a convex – or outward-curving – lens.
These mirrors are convex, causing rays to converge into a real image, which is then magnified through an eyepiece or projected directly onto a digital sensor.
While Galileo used a concave lens for his eyepiece, the standard refracting telescope uses a convex, converging lens for both the objective lens and the eyepiece.
And if the molecules in the liquid are more attracted to each other than to the container, as is the case with mercury and glass, they'll form a convex meniscus.
Light comes in through the cornea and pupil and hits the lens — the convex, transparent disc that focuses that light and projects it onto the retina, which makes up the inner layer of the back of the eyeball.
They keep a Whale's Rib of an incredible length for a Miracle, which lying upon the Ground with its convex part uppermost, makes an Arch, the Head of which cannot be reached by a Man upon a Camel's Back.
