How to Clean Anti-Glare-Coated Glasses Use warm, never hot, water and mild soap to clean your anti-glare-coated glasses. As is true for any eyeglass lenses, your primary objective when cleaning anti-glare lenses is to avoid scratching them. Using the same steps as you would clean regular eyeglass lenses: Wet your lenses with clean water or an approved eyeglasses cleaning solution. Using a clean microfiber cloth, gently wipe each side of the lens in a circular motion to remove residue. Repeat steps 1 and 2 until the lenses are clean. Available Anti-Reflective Treatments and Lens Options An anti-reflective coating is available for all types of eyeglass lenses, including reading glasses. To include the premium AR treatment, choose either the Standard or Premium option when adding lenses to your frames. You can select these treatment options for single vision, progressive, bifocal, reader, or plano (non-prescription) lenses. Standard Lens Option The Standard lens option includes DuraClear™, a premium anti-reflective treatment that lets in 99% of available light and improves clarity and contrast. Lenses coated with Duraclear help prevent eye strain and are easy to clean, thanks to the superhydrophobic coating. Premium Lens Option The Premium lens option includes Blue-Violet Light Filtering with BlueReflect™ to filter blue-violet light, as well as premium anti-reflective treatment and UV protection. BlueReflect provides clearer vision while you use digital devices. Buying your glasses online can be less expensive than visiting your local optician, and we make the process simple. Are Anti-Reflective Lenses Worth It? For most glasses wearers the benefits of lenses with an anti-reflective coating far outweigh the disadvantages. The long lifespan and everyday vision improvements AR-coated lenses offer are well worth the minor addition to the overall price tag of a new pair of glasses.

Anti-reflective coatings help to reduce eye strain and fatigue and increase comfort while using screens and driving. This is extremely important if you spend any significant time driving at night, whether commuting, working, or going out to dinner. With fewer reflections, more light can reach your eyes, improving visual acuity and reducing many risks associated with nighttime driving.

This objective lens will achieve the greatest magnification and has a total magnification of 1000x (10x eyepiece lens x the 100x objective equals 1000).

Polarization, which is an anti-glare coating that is used on sunglasses only. Many top sunglasses makers, including Maui Jim, will infuse their lenses with polarization and anti-reflective technologies in order to provide the brightest, clearest vision.

Combined with the eyepiece lens, this lens will provide the lowest magnification power. For example, 10x eyepiece lens, multiplied by the 4x objective lens gives a total magnification of 40x.

The objective lens and the ocular or eyepiece lens are in combination responsible for magnification of the specimen being observed.

The minor disadvantage to an anti-reflective coating is that it can become marred or scratched over time. Clean your lenses properly and often in order to avoid scratching caused by normal wear and tear, and always store glasses in a case. Besides the minor cost increase the coating adds and a minimal chance for scratching, an AR coating offers no real disadvantages.

The objective lens is at the bottom of the eyepiece tube and is responsible for both total magnification of the specimen, as well as the resolving power of the microscope.

Resolving power is also a very important metric since magnification power is of little importance if the resolution is not high. Resolution is defined as the ability to distinguish 2 points as two points.

Light microscopes are relatively complex pieces of equipment in nature with multiple different parts, some which are more complex than others.

While the total magnification is determined by both the objective and ocular lens, the resolution is determined by the objective lens alone.

Ensuring your lenses are are kept clean will increase the performance and clarity of your microscope’s images.  There are many products on the market but nothing specifically made for microscopes.  We found a good quality Digital Camera Cleaning Kit was a great option, something with wipes for removing grease and oils and a puffer bottle for blowing away dust.

As previously mentioned, the ocular or eyepiece lens is located at the top of the eyepiece tube and is where you position your eye to observe the specimen. The ocular lens typically has a low magnification (10x) and works in combination with the objective lens to achieve a greater magnification power.

Because glass and air have different refractive indexes, light bends at different angles when it passes through each of them. When using the 4x, 10x, 40x objective lenses, the light refraction that occurs when looking through the lens to the specimen on the glass slide is not very noticeable. However, when using the higher power objective lenses, for example the 100x, the light refraction is much more obvious.

A drop of special oil which has a similar refractive index to glass, is placed on the cover slip over the specimen.  The oil immersion objective lens is immersed in the oil, rather than air, enabling a clear image of the specimen.

Often overlooked is the cleanliness of your optics. Daily use in any environment will attract dust and small debris, and when handling your lens, oils from your body can be transferred. This is particularly the case around the eyepiece.

Premium anti-reflective treatments also include a superhydrophobic coating that repels dust and resists water, oil, and fingerprints so your lenses are easier to clean. FramesDirect.com offers premium anti-reflective treatment as part of both the Standard and Premium lens options.

The lenses of the microscope are fundamental to its function as they provide the magnification power that allows the microscopic specimen to be seen or observed in greater detail. The two main types of lenses found in light microscopes today are called the objective lens and the ocular lens, which is also called the eyepiece.

For example, if you are looking down a microscope, the resolution power relates to the space you can see between two points. A very low resolution would result in a blurred image and would prevent proper observation of the specimen.

This objective lens is the next lowest powered and is often the most helpful when it comes to analyzing glass slide samples. The total magnification for this lens is equal to 100x magnification (10x eyepiece lens x the 10x objective equals 100).

This objective is often referred to as the scanning objective lens since the low power provides enough magnification to give the observer a good overview of the entire slide and sample.

The primary purpose of an anti-reflective (AR) treatment for prescription eyewear lenses is to allow more light to pass through the lens and therefore reduce glare. The coating reduces reflections on the lens to reduce distractions and allow you to see more of what’s ahead of you. It also increases your eye comfort while you use digital screens, read, or drive and helps prevent eye fatigue. We strongly recommend an anti-reflective treatment for all lenses.

Disadvantages of anti glareglasses

Anti-glare coatings shield your eyes from external light sources, while anti-reflective coatings react to both external and internal light. Lenses with an anti-reflective coating also work better to filter blue-violet light from sunlight and indoor light. Whether you choose anti-glare or anti-reflective lenses, you’ll appreciate the benefits of reduced glare and reflections in your vision.

Since it still provides a good amount of magnification at a good distance from the slide, there is a limited risk of it breaking the glass and potentially ruining the sample. That’s why this objective lens is often preferred before going for a high powered lens.

The majority of compound microscopes come with interchangeable objective lenses, which have different magnification powers. This commonly includes 4x, 10x, 40x, and 100x objective lenses.
