Are the crystalline lens as effective as the yellow?

As effective? That depends on what you mean... As effective against eye strain.. No. Period.This is readily confirmed at Gunnar's website:http://www.gunnars.com/view_crystal_lenses.php"The CRySTALLINE lens tint and coating formula is designed specifically for the graphic designer, video/film editor, or creative visual artist that requires an equally balanced color spectrum. If your profession does not allow for a shift towards the warmer part of the color spectrum, with enhanced contrast ie. your tasks require you to design or work in true color, then this lens option is for you. However, if your profession does not require you to perform many daily tasks in true color, then AMBeR is the most effective lens choice." As effective? That depends on what you mean...

I don't think there is a difference in my opinion but if your going to be shooting outside any I would recommend yellow tinted lens they work great inside and out

Absolutely. I wear tri-focular lenses and only lose a small portion of the field of view. Slow panning is the thing you use when looking for game in the brush or trees and the field of vision is not noticeable.

No, they are all the same color. Two of us got them with no amount of magnification and I got a C3. They all look exactly the same. Actually they have a very light yellow color tint to the lenses which, when on, is barely noticeable.

From the little bit of research I've done I would say yes. There are reports of people having seeing the crystallization pattern I believe it's called with as little as 8x magnification but another site recommended 100 times magnification for clarity and surety. This is a website I found that seemed decent: http://www.ovulation-calculator.com/microscope.htm Best of luck, Father of identical 3 yr old twins girls!

I can notice a slight magnification, but it helps more with clarity vs magnification. Good investment if you find yourself having eye strain related headaches multiple people in my department have bought these and noticed a decrease in fatigue.

This one is only clear but they do sell some others with dark, yellow, and clear lens

Hi Carlos, Just a slight improvement and longer focal range. If you want a noticeable improvement on image quality, we recommend using prime lenses. -Anthony

Random answer. I think the yellow reflects yellow light from the monitor. Reducing eyestrain?

I believe it is the same......it is the lens power.....mine work fine but the Lights are not quite bright enough.

Iso wont make a difference. You will need to do some math to calculate your "effective F stop". Ne = N(1+M/p)N = f-numberNe = effective f-numberM = magnification = extension from infinity focus / focal lengthp = exit pupil diameter / entrance pupil diameter

Yes, this is effective to block blue rays - in fact you will see everything a little bit yellowish - but you will adjust quickly.

No. This lens has a magnification factor of .31. True macro lenses have a magnification of 1X (meaning the object is actual size on the surface of the sensor) or more. I'm not sure how small your intended subjects are but a macro lens might not be powerful enough to reveal truly microscopic details, i.e., great for insects, not so helpful for cellular structure.

No, At least they won't help me that way. The yellow tint does not effect the sight, no coloration. They only screen blue light rays. Other wise you won't know you are wearing them.

Maybe, the lenses are yellow tinted, I dont play tennis so I dont know if that will affect the game. I think they will stay on your face through the game play.

I did mine at least 4 months ago. I noticed the lenses started to have a haze/showing sign of yellow already. Understand, I live in Houston, Texas, where we got sunshine most of the time, including winter.

There is not much a difference. So which way is more connivance. I prefer to the one on the lens.
