Edge polishing give a high sheen to the edges of the lens, which some people prefer on the lenses used in rimless eyeglass frames. In some cases people have lenses that are substantially thicker than the frame and they prefer to have a polish on the edges.

What is Edge polish on lenses?

An “edge polish” changes the appearance of the lens edges from matte to shiny. This can elevate the appearance to something more refined and almost jewelry-like, especially when you select semi-rimless / “half”-frames, or completely rimless / no-frame styles.

How do I get the white edges off my glasses?

If you don’t like the white edge you can request the edges be polished and if you really want to eliminate the reflections of the edges off the lenses you can also opt for anti-reflection coatings. Also, if possible, you might also consider getting a frame with a smaller eye size to reduce the edge thickness.

What is high luster edge polish?

Aspheric lenses improve the cosmetics of a pair of glasses by using surface curves that are flatter centrally and progressively flattened (in plus prescriptions) as one moves from lens center to edge.

What polarized lenses?

Polarized lenses have a special chemical applied to them to filter light. The chemical’s molecules are lined up specifically to block some of the light from passing through the lens. Think of it like a miniblind hanging in front of a window. Only light that passes through the blind’s openings can be seen.

Are trivex lenses worth it?

Trivex lenses tend to cost more than polycarbonate or standard plastic lenses. But if you want what many eye care professionals consider to be the best combination of safety, comfort, appearance and optical performance for most eyeglass prescriptions, the Trivex price tag may be an investment worth making.

Why do plastic eyeglass frames turn white?

Most plastic frames are cellulose acetate. While in itself this plastic is transparent to UV, in the presence of surface contaminants it can oxidize–growing pitted and, eventually, brittle. This oxidation is almost certainly the source of the cloudiness.

What is bevel edging glasses?

The bevel—that (usually) V-shaped cut on the lens edge that allows the lens to sit securely in the frame—was once the domain of lens techs with hand tools. These days, it is cut in seconds as one of many automated steps in the contemporary edging process.

Who is the father of microscope?

Antoni van Leeuwenhoek (1632-1723): father of microscopy.

What does the first microscope look like?

The early simple “microscopes” which were really only magnifying glasses had one power, usually about 6X – 10X . One thing that was very common and interesting to look at was fleas and other tiny insects. These early magnifiers were hence called “flea glasses”.

Why can I see my eye reflection in my glasses?

A common problem with prescription glasses and sunglasses is called back-glare. This is light that hits the back of the lenses and bounces into the eyes. … In bad cases, you can actually see the reflection of your eye in the lens.

Is anti reflective coating the same as anti glare?

In general terms anti-glare coatings use either diffuse particles or etching on the substrate’s surface, while anti-reflective coatings utilize film structure over the substrate surface. … There are however instances where both solutions can be used in conjunction for maximum reflection/glare reduction.

Is anti reflective the same as blue light?

Anti-Reflective vs. When it comes to the similarities of anti-reflective and blue light coatings, they‘re both AR coatings, so they have the benefit of minimizing glare. The difference is the blue defense coating has the added blue light-blocking capabilities in addition to the AR coating.

Who invented Trivex?

Trivex was originally developed for military use by PPG Industries in 2001. The company then took this ultra-strong, lightweight material and applied it to consumer optical needs. The material is a urethane-based pre-polymer, named after the three important properties of this material: Superior optics.
