For some people it means nothing, and they can adapt to whatever lenses they get next time.  For the majority of people, however, you want to get similar lenses in future so you don’t have the worry of not adapting properly to a new kind of lens.  Changing an eye prescription carries with it enough to worry about without adding more variables.  If you are used to having an anti-reflective coating, make sure you get one the next time you order new glasses.

The neutral density (ND) filter is one of the basic gears that should be included in every landscape photographer’s camera backpack. Many beginners may don’t know how, where, and when to use them. In this article, we will introduce some basic knowledge about it.

So if you have an ND filter with strength or intensity of 2 all you need to do is turn it into a fraction by putting a 1 above it. So ND filter of 2 is going to let in half the amount of light. An ND filter of 4 is going to let in 1/4 amount of light and so on. So if it’s a 3 stops reduction, it will let in 1/8. if it’s a four-stop reduction so it’s an ND 16 it’s going to let in 1/16. if it’s an ND filter then reduce it by 5 stops that would be an ND 32 . and that’s going to let in a fraction of 1/32. and so on and so forth.

Hi Cheryl, Appreciate your comment! The anti-reflective coating does make a difference in reducing reflections and enhancing clarity.

Make sure you clean your anti-reflective coated lenses wet, not dry.  A dry cloth will rub any grit into the coating and likely scratch it.  Also, make sure not to use any harsh chemicals on your glasses.

If you don’t have the anti-reflective coating, the glare will appear the same color as the light reflecting, often white, and reflections will be strong.  No matter where you hold the glasses, reflections will be apparent.

First of all, what is an anti-reflective coating?  An anti-reflective coating is a layer applied to glasses lenses to reduce glare and reflectivity.  This can be especially helpful in making stronger prescriptions appear more attractive.  The reason for this is that the material used is often high index plastic, which is more reflective than regular plastic lenses, and therefore makes the reflections more noticeable.

The ND filter is a filter that, placed before the lens reduces the amount of light reaching the camera's sensor. It acts like a pair of sunglasses to your lens.

A stop is an arbitrary amount of light. If you have a shutter speed that’s twice as long as one before. You’re letting in twice the amount of light that is one stop. ND filters are rated in the amount of light that they reduce coming into the lens. so if we say this is an ND filter with the one-stop intensity that means it would let in half the amount of light as it did before and this is how ND filters are rated. So they have different intensities from 1-9 or 10,000?

1 stop, 2 stops, 3 stops, etc. Sometimes these are referred to as EVs, for exposure value. These are probably the most convenient measurement because they tell you how many stops they'll adjust your exposure by.

ND filters come in different strengths or darkness levels. For the photographer, the easiest way is to have ND filters that tell you how many stops of light they will darken your exposure. Most brands of ND filters label the ND filters with either a factor number or optical density number. But for the photographer, neither of them is referred to the number of stops by which the light is reduced.

I too hate the “anti-reflection” crap on my glasses. It causes reflections to be worse. I would gladly pay more to have it not applied in the first place.

Video shooting with wide aperture lenses outside is another application if you want to shoot in a 2.8 or even wider. you are doing the day when it's very bright. way too much light coming into the camera kind of locked into our shutter speed. You cannot turn the ISO down further and that is a problem you can't solve without an ND filter. many high-end video cameras have ND filters built into them.

Checking whether your glasses have an anti-reflective coating on them or not is relatively simple.  When you hold your glasses, tilt them this way and that and look for glare.  What you will see if you have an anti-reflective coating is a bit of glare, but mostly a greenish and pinkish color.  You will also notice that if there is nothing truly bright (like an overhead light) trying to reflect off the lens, it appears quite clear.

2x, 4x, 8x, etc. Sometimes these are referred to as ND2, ND4, ND8, and so on. These refer to the amount by which the light is diminished. An ND2 filter halves the light, while an ND8 filter reduces it to one-eighth.

Again if you’re trying to go with a very very wide aperture on a sunny day well cameras have sync speed limits which means you cannot really use super-fast shutter speed and so one of the best ways to manage that is to lower the amount of light coming in-camera through an ND filter.

If you have high index lenses, an anti-reflective coating can improve the appearance of the lenses since the lens itself is more reflective.  This means that not only will you be able to see better without the distraction of reflections, but that people will see you and not reflective glare on your lenses.
