when the degree of convergence of a convex lens placed in air increases, we say its convexity has increased. as the power of a lens is the measure of degree of its convergence or divergence, we can increase the convexity of a lens increasing its power
this is further achieved by decreasing its focal length.
as focal length is inversly proportional to the refractive index of lens we have to decrease in order to increase its convexity.

During close vision lens convexity is?
decreased
During close vision the lens convexity is?
decreased
What part of the eye are made of cells?
the increase in thickness and convexity of the eyes lens in order to focus the image of an external object upon the retina.
When convexity of the lens is increased and light refraction does what?
The light refraction is decreased.
What is medical convexity of the spine?
If you mean the medical term for an increase in convexity of the spine, it's lordosis, and increase in the curve of the back. Hope that helps
The suspensory ligament is what during distance vision?
During distant vision, the ciliary muscle is relaxed, the suspensory ligament is taut, the convexity of the lens is increased, and light refraction is decreased. During close vision, the ciliary muscle is contracted, the suspensory ligament is relaxed, lens convexity is increased, and light refraction is increased.
What is spherical lens?
Any convex lens bulges out from each side. It is thicker at the centre of the lens and thinner at the edges. I am supposing that a spherical convex lens has convexity on both sides, but on one of those sides the glass is so curved that it has the shape of part of a sphere.

What happens to total magnification if increase objective lens?
Total magnification is calculated by objective times ocular lens. So if you increase the objective lens is directly related to an increase in magnification.
How magnification can increase?
Use a magnifying lens. (concave)
What is dark spyro's element?
Convexity.
What is a tele conversion lens?
A tele-conversion lens attaches to a digital camera to increase the lens magnification. It enhances the telephoto effect and adds focal length.
