Mirror Coating

[majucalicut]

Dear friends

I would like to know the below things and the answers will be highly appreciated.

1. What is the benefit of mirror coating and what are the materials used while coating and how the process takes place.

2. How mirror coating benefited over polarised lens and how can we compare polarised and mirror coating

Please help me to the answer:hammer:

Mirrors and polarizing lenses are two different animals.
Mirror coats make the lenses darker to look through (and to look at). They do this by reflecting light, thereby reducing transmission. If you mirror coat over a tinted lens, you are reducing transmission by both absorption and reflection. A blue mirror won't make the lens blue to look through; a silver mirror won't make the lens silver to look through.
Polaroid/polarized/polarizing lenses allow light waves vibrating in one meridian (usually vertical) to pass through the lens, and block waves vibrating the opposite way (usually horizontal). The polarizing effect also "darkens" the lens, but independently of any absorption or reflection that may also be present.

Adding to finefocus's answer:

The original function of a mirror coating is to reduce infrared transmission (heat) and to decrease light transmission of lenses without increasing thickness of lenses, when only glass was available for tint purposes. Metal oxides were used and application was typically applied to a heated lens in a vacuum chamber.

I would believe that a cricket player might have a slight advantage when their eyes are not visible to the opponent, and mirror would add a slight tint, over and above the tint, of their base lens?

Only by blinding their opponents with flashing reflections. Otherwise, no more effective than other tinting methods.

Great questions , besides being very profitable for any practice Mirror coatings do serve a practical purpose as well as being very fashionable today. Customer has the best customized sunwear for them.

We coat thousands of mirrors a week so we do know a little about the subject.

For fielding in Cricket, mirror coated lenses can help reduce extreme glares from various light sources such as sunlight and stadium lights, making the job easy for the fielder. Hey, may be more efficient catches and no misses...right?

Polarized lenses do also help reduce glare (most in the polarizing plane its made in) and reflectiosn off the shiny surfaces, but adding mirror coating to the polarized lenses can create an ultimate eyewear that helps eliminate reflections and glare altogether.

Mirror coatings on sunwear lens ,polarized lenses are a plus factor in reducing all levels of glare and blinding sunlight. It's all about safety and comfort of the individual.

Mirror coating on RX lenses is possible? can you make them ruby or ice mirror coat? I'm from Malaysia, any idea which lab can provide that?
Thanks

I just got my polarized, silver mirror, AR (backside) coated lenses in from KMARS optical. Wow! Great quality

Think you will find all you want to know about the application of mirror coatings and the manufacture of same in any eighth or ninth grade science book.
Look under electroplating, mirror plating.
