While anti-glare and reflective lenses are often marketed as the same or indistinguishable products, there is at least one key difference: anti-glare lenses protect against just external light sources, while anti-reflective lenses protect against both external and internal light sources, protecting the wearer more thoroughly from harmful light rays.

Focusing a microscope typically will involve starting with a lower magnification objective and then working ones way up to a higher magnification. A common mistake is to not follow this sequence, either never bringing magnification up to a high level or, more commonly, to skip attempting to first focus at the lower levels of magnification. Note that it often is possible to skip the lowest level of magnification. If you are having difficulty focusing your microscope onto the specimen, however, then one thing you might try is to start over at the lowest magnification.

The terms anti-glare lenses and anti-reflective lenses have been used interchangeably since their inception. The average person has a general understanding that both anti-glare and anti-reflective lenses help to reduce the light entering the eyes and provide a clearer vision for the wearer. While this is a fine general understanding, there are some small differences between anti-glare and anti-reflective lenses: here’s what you should know.

While anti-reflective lenses work similarly to other lenses, diffusing rays that enter the lenses, they actually are slightly more effective as they protect against both external and internal light, while anti-glare glasses only protect against external light. Internal light refers to when light rays are in a transitional state between your lens and the air, and can cause damage to your eyes over a long period of time.

Anti-glare lens coatings work to reduce the amount of light entering the eyes to prevent damage and help improve eyesight and surroundings. They do so by equipping the lenses with a diffusive property. This means that instead of a light ray bouncing off your lenses, it is instead broken down into smaller, weaker, and mostly unnoticeable rays that are not harsh on the eyes.

Once we understand the key difference between anti-glare and anti-reflective lenses, it’s easy to determine which one is more effective, safer, and more worth the purchase. The answer, of course, is anti-reflective lenses over anti-glare.

The eyepiece has several major functions: ○ The eyepiece serves to further ... eyepiece: ​the lens light passes through before getting to your eye.

The lens (or lenses) that sit immediately above the specimen (as found on a slide) is called the objective lens (or lenses). The reason for the name is that the specimen is also known as the object and the objective lens is immediately adjacent to the object (rather than immediately adjacent to one's eye or eyes) The pathway of light is: light source → condenser → iris diaphragm → stage → object/specimen → objective lens → ocular lens → eye or camera. The objective lens will have certain associated magnifications such as 4×, 10×, 40×, and 100×. See also Parfocal.
