Anti-reflective coating has many benefits, but it is an add-on so your anti-glare glasses will cost more. If you’re considering it, talk to your eye doctor so they can help you decide if it’s worth it for you.
The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.

Light is critical for good vision. When light enters your eye, it hits the retina — the light-sensitive layer of tissue at the back of the eye. Photoreceptors cells in the retina turn the light into electrical signals. Those cells send the electrical signals to the optic nerve, and the optic nerve sends them to the brain. The brain turns those signals into the things you see.
The more light that reaches your eyes, the better you can see. Anti-reflective coating (also called “AR coating” or “anti-glare coating”) decreases the amount of light that is reflected off the front and back surfaces of your eyeglass lenses. This lets more light pass through the lenses and reach your eyes.

When drawing what you see under the microscope, follow the format shown below. It is important to include a figure label and a subject title above the image. The species name (and common name if there is one) and the magnification at which you were viewing the object should be written below the image. All relevant parts of the drawing should be labelled on the right side of the image using straight lines. Lines should not cross. Drawings should be done in pencil, while labels should be in pen or typed. Remember that total magnification is determined by multiplying the ocular x objective.
The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus. A common exercise to demonstrate depth of focus involves laying three different colored threads one on top of the other. As the observer focuses down, first the top thread comes into focus, then the middle one, and finally the bottom one. On higer power objectives one may go out of focus as another comes into focus.

AR coating is especially beneficial on high-index lenses. These lenses are thinner and lighter than regular plastic lenses. They can reflect up to 50% more light than regular plastic lenses so less light reaches your eyes.

Most premium AR lenses include a surface treatment to seal the anti-reflective layers and make the lenses easier to clean. These treatments also repel water so you won’t get water spots on your lenses. Some lens surface treatments repel both water and oil from your skin.
The exact formula of anti-reflective coating depends on the company that makes it. In general, AR coating is made of many very thin layers of metal oxides that are applied to the lens surface. The layers alternate between high and low refractive indexes (the refractive index measures how the lens refracts — or bends — light). The more layers there are, the less amount of light that’s reflected onto the lenses of your anti-glare glasses.

You want your glasses to give you the best vision possible. Adding anti-reflective coating to your lenses is one way you can optimize your vision.
The majority of lenses with anti-reflective coating have a very light tint, which is usually green or blue. The color depends on the brand of coating that’s on your lenses.
Most regular plastic lenses reflect about 8% of the light hitting the lenses so only 92% of available light enters the eyes. AR coating eliminates almost all reflections so up to 99% of light passes through your anti-glare glasses and reaches your eyes.
