Spectrophotometer PHOTON RT or spectral characteristics of glasses Gunnar and Polaroid
Yesterday, a new device appeared on my workplace - a new spectrophotometer PHOTON RT (made in Belarus).
After reading the instructions (important point!) I immediately wanted to try out this device forpersonal use.
So as the test objectmice used glasses for the computer brand GUNNAR (the hero of this article), which I have recently appeared and Polaroid sunglasses.

A friend from work claims that these points are worthless and similar are sold at the hardware store, but only an order of magnitude cheaper. I did not have glasses for builders, therefore we study the characteristics of only GUNNAR :-)

These glasses POLAROID give a little yellow color (slightly different color than in the photo).

Picture. Spectral characteristics of GUNNAR and POLAROID glasses
On the graph there is a characteristic of the filter UFS8: confirmation that the deuterium lamp is working correctly.
Both glasses (GUNNAR and POLAROID) have a block of radiation up to a wavelength of 0.4 microns, which means that the eyes are protected from UV radiation. GUNNAR glasses can also be used on a sunny day outside and not be afraid to damage your eyes. But, pay attention, the standard GUNNAR glasses come with diopters - about 0.3!
Note: as far as I heard from familiar opticians, the whole problem of cheap sunglasses is that they "cut" the general background, but they let in UV radiation from the sun. It turns out that when the light passing through such glasses falls, the pupil expands and the eye “grabs” even more UV radiation than in the absence of glasses as such.
My conclusion: GUNNAR crush the blue color from the monitor, which improves the contrast and clarity of the elements on the monitor. Another “kakbe” is a bit of advertising :-) Also, due to small diopters, the image on the screen seems closer. Eyes by the end of the day not so tired, the overall redness of the eyes is less. Some are against, but I'm already used to these points. The monitor is not as red-eyed as it is without them :-) But it seems to me that the price for them is too high.
R.S. If someone needs to measure on a spectrophotometer, then contact :-)
