Transition lenses contain photochromic molecules that darken when exposed to UV light, and become lighter when the UV light diminishes. This allows the lenses to automatically adjust to different lighting conditions, providing both clear vision indoors and UV protection outdoors.
The objective lens and the eyepiece lens work together to magnify the image of an object in a microscope. The objective lens magnifies the image first, and the eyepiece lens further magnifies the image for viewing.
A two lens microscope uses a combination of an objective lens and an eyepiece lens to magnify an image. The objective lens captures the image and magnifies it, then the eyepiece lens further magnifies the image to allow for viewing. This combination of lenses allows for high magnification and resolution of the specimen being observed.
It is actually work not force...
A double-convex lens is a type of lens that is thicker in the middle and thinner at the edges. It converges light rays to a focal point on the opposite side of the lens. This type of lens is commonly used in magnifying glasses and camera lenses.
A convex lens works by refracting light that passes through it. As the light enters the lens, it bends inward and converges at a focal point on the opposite side of the lens. This convergence of light helps to form a real or virtual image, depending on the object's distance from the lens.
Photochromatic lenses are commonly called transition lenses. The lens is clear, but when exposed to the sun's UV rays, they will darken like sunglasses.
It may be possible to coat your existing lens with a transition coating, but it is important to consult with an optician or optical laboratory to determine if your specific lens material and coating are compatible. Additionally, the quality of the coating and process may vary depending on the original lens material and quality.

It depends if the camcorder has the physical settings to attach the lens.
Transition glasses darken in sunlight and stay clear indoors, offering convenience and UV protection.
Yes. If the lens is a EF or EF-S lens, it should work fine with the t1i
What some people call Transitions, a registered trademark, lens are designed and built to react to light levels. Low light the lens stay transparent, when bright light hits the lens the way the lens are made makes the lens change to the apropriate level of dark in a fraction of a second.
biology
NO. The lens is required to focus the image on the CCD sensor.
Each concave lens bends light to make the object appear larger
The amount of curve (convex) in the lens determines the strength of the lens, thereby determining the effectiveness (or strength) of the lens. This is how the prescription strength of contact lenses is determined.
The magnifying lens that a watchmaker uses for detail work is called a loop.
