Treatment Of what material I choose my glasses? Lens Lens Advanced

As we have seen each material has its strengths and weaknesses, know what is the best material for us depends on how you use we will give the glasses or our activities.


If we work in an environment where there is a lot of dust or dirt, the lenses will scratch over time despite having scratch-resistant treatment, so it would be desirable to use a mineral lens.

But if we work indoors where we do not have this problem, we can choose an organic lens because it is more convenient to be lighter, in fact the lens organic lens is the most widely used today.

If we have a very active lifestyle, or we will use the glasses for your sport is desirable that the polycarbonate glasses out, because apart from being slightly more resistant to impact.

Can Anyone Buy Zigzags

currently ophthalmic lens manufacturers are introducing new materials that bring more quality to existing products.

Different laboratories have improved polycarbonate, improving the internal tensions that had this material, so that makes it much more impact resistant and lighter, so it is especially frames specified in the air (drilled) and for users who play sports.


Another novelty is the emergence of free-form monofocal or digital carved anew, this method was first used carved with progressive lenses for increased field of view of these lenses, is being applied to monofocal lenses . These lenses are recommended for users with high rankings, as conventional lenses have large distortions when we look outside the optical center. With these lenses provides enhanced visual field and contrast sensitivity, which is a huge improvement in visual quality people with a medium-high graduation.

What Is A High Nln Exam Score?

polycarbonate lenses are a type of organic lenses, ie, consist of a polymer, but unlike the organic polymer forms long chains that parallel with few links between them, this provision makes the lens present a high impact resistance.

The great advantage of polycarbonate lenses is that they are more resistant to organic lenses, so it is recommended for rimless eyewear (drilled). Furthermore, the refractive index is 1.6, so a lens is more fine organic a CR-39 lens. Another advantage is its lightness due to low density.

The disadvantages as with organic lenses is its ease of scratch, so it is necessary to use a scratchproof treatment or hardened to prevent scratching easily. It also features optical quality least the low-index organic lenses, so that chromatic aberration (the appearance of colored shadows around the objects) is more evident when looking through the lateral ends of this type of lenses.

Polycarbonate Lenses Lenses

organic lenses are composed of organic polymers. They are popularly known as plastic lenses, although the polymers used are selected by their optical and physical properties.


refractive indices, as we saw in the previous post, is the indicator of the reduction of the lens are different from the minerals lenses, and may differ depending on the home than the market, this happens in cases of high rates. The lowest lens corresponds at a rate 1.5 (material known as CR-39), and we can find the 1.56, 1.6, 1.67, 1.7, 1.74 and finally the 1.76 organic lens is smaller than currently exists.


For organic lenses and light weight reduction if they are united, unlike the mineral lenses, but as was the case with these, increasing the reduced optical quality is usually worse, becoming more apparent aberration spherical when we look at objects at the edges of the lenses (see objects with colored shadows.)

The advantages organic lens are its lightness and resistance impact.

Its great drawback is its ease of scoring , to avoid this treatment appeared to harden the lens, making it more resistant to scratching, but eventually end up scratching before a mineral lens. Despite this, and thanks to the firming treatments organic lenses are the lenses of reference in recent years.
