Ten questions about polarized glasses. Part 1

Tinted glasses are considered an indispensable attribute of security and safety personnel. But in North Korea, where I happened to be, a man with dark glasses, on the contrary, is more likely to be mistaken for an agent of unfriendly intelligence. You and I (or at least most of us) do not belong to the number of security guards or spies, nevertheless, we use glasses with darkened, or rather polarized, glasses very often.

Didn’t use polarizing glasses before. Now I bought them, tried them, but, frankly, I expected more – they do not “pierce” the depth, as we would like. Maybe the glasses are not quite the same?

More than anyone else, we anglers tend to overestimate a lot a priori. Therefore, we demand from the new rod that it allows you to feel every pebble and every twig by two, from the echo sounder – to show the fish, as in Cousteau’s films, but the glasses, which are supposed to “eliminate glare” from the water surface, are simply obliged to see what is happening under water, well, something like a night vision device allows you to see in the dark …

In fact, the capabilities of polarizing glasses are very modest, and this should be borne in mind from the outset. Glasses provide real help in the area closest to us – for a person standing at full height, this is approximately within a radius of up to 20 meters. Outside this zone, there is also some effect from polarizing filters, but the benefit from it is already very small. And the main working range of distances, where glasses have the greatest effect, is 5-15 meters. Here, they allow you to see under the surface of the water much that would go unnoticed for a simple eye. And, of course, polarizing glasses are hardly able to help if the water is not clear enough.

What should be the first thing to keep in mind when choosing glasses – the degree of polarization, the color of the filters, the brand, or something else?

For many, this will seem unexpected, but I would advise as a primary criterion to be guided by how the glasses fit on you. The slightest sensation of discomfort, whether it be a feeling of tightness from the temples or “fidgeting” on the bridge of the nose, is already a sufficient reason to try another model. What is very significant, the same model of glasses can perfectly fit on one person and be completely unsuitable for another. Once I tried the entire range of Flying Fisherman polarized glasses – none fit, while many of my friends use glasses of this brand, and I have not heard any particular complaints from them. All other factors of choice are, of course, important, but after the issue of mechanical comfort has been resolved.

One of my acquaintances fitted glasses to his face, heating the temples in hot water and then bending them. How is it – in the order of things?

The possibility of adjusting the geometry of the temples, if it happens in the very concept of glasses, then, as a rule, we are talking here about expensive models. As for cheap ones, here the bend of the temples is already pure amateur performance. On the other hand, if cheap glasses break because of this, it’s not a pity, it will be worse if expensive ones break. Therefore, it makes sense to ask the seller how guaranteed you are against troubles if you start to be smart with the bows. Of course, a clear answer to this question can be expected not in a stall, but in a serious store, for which polarizing glasses are one of the important items in the assortment.

I can refer to my experience. I didn’t have to bend the plastic bows, but I did it with the metal ones more than once. In this case, there is no need for heating, it should be bent slowly and in two or three stages, after each figuring out whether it is worth continuing further. Finally, some models of Aqua glasses provide for the possibility of repeated bending not of all the arms, but of the part that is in direct contact with the auricles – this part is made in the form of a plastic metal frame covered with a rubber shell. It turns out very convenient – glasses can be adjusted to almost any person.

Cheap glasses have plastic filters, expensive ones have glass filters, don’t they?

Five or seven years ago, it really was so – not always, it is true, but for the most part. Now the picture has rather changed to the opposite. More precisely – in the cheap price category there are glasses with plastic filters, glass filters, and expensive, but still expensive – plastic is being used more and more often. The latter is a consequence of the fact that now those types of plastics have become more accessible, which have a very high degree of protection against scratches and impacts. But such plastics cost quite serious money. As a result, in relation to plastic filters, we can talk about the following “wear resistance scale”. The lowest level is what I would call “disposable” glasses. Very often the filters in them are even tough, but kind of “semi-soft”. Such glasses are not intended for fishing, but, say, for a week-long trip to a ski resort, where, by the way, there is a minimum of sand and dust, which such glasses are very afraid of, becoming unusable after two or three days in our fishing conditions. And in the same mountains they do not live much longer, therefore they are “disposable”.

The next level is Polaroid glasses, bought at a stall that sells all sorts of things. The price is not high, the season, if you treat them very carefully, they will hold out. Unless in their shape they are the same as most purely beach glasses, that is, these glasses are designed for the fisherman in the last place. We are more interested in special fishing goggles, which at a price differ little from the same “Polaroid”, but provide a wider field of view due to wider filters and special geometry. In terms of wear resistance, they, however, differ little from the previous ones, and the average time of their life is a year and a half. Finally, plastic glasses from expensive companies, as a rule, are divided into two or three levels in terms of prices, but even the lowest of these levels (which is about 600-700 rubles) suggests that the filters will last at least two years.
