polarized lenses of hard resin
Questions and Answers How does a polarizing lens?
-The light is transmitted into space by vibrating in many directions when it passes through a polarizing lens, this channeled light rays and makes them move in one direction only. This effect eliminates the reflected rays including those imperceptible to the human eye.
What is the difference between a polarizing lens and a normal colored lens?
-Normal sunglasses only decreasing light transmission while reducing the intensity of the polarized lenses eliminate reflected rays allowing a more comfortable, increasing the depth of field and improving the perception of colors.
What is the difference between a polarizing lens CR39 and polarizing filters that are used for clip-on?
CR39-A polarizing lens is optically perfect because its surfaces are parallel and the optical beam does not suffer any distortion. A polarizing filter can not have parallel surfaces because it comes from a flat plate molded. Obviously not all of the polarizing filters are the same: there are good quality but also of the lowest level.
E 'can have a polarizing lens colorless?
No, not possible. the coefficient of polarization of a lens is proportional to the density of staining of the film. The lighter the film, the more I'll lower the coefficient of polarization. The coefficient of maximum polarization (99%) is found only in the panoply of dark gray lenses, Contrast Grey, Dark Brown and Green.
Some CR39 Polarized lenses are available from stock in finished form? Only
-plano lenses and plano lenses with bifocal addition FT28 are in stock and not the building.
Then the polarized lenses are all remedial construction?
-Si, corrective lenses single vision, bifocals and progressive are all built. The semi-finished products must be placed on the axis of polarization in diopter and lens must be cut and assembled on the same axis. The optician must order the polarized lenses panoply clearly indicating whether the lens left or right, any axis for correcting astigmatism and the system used (taboo or international).
What is the most effective way to demonstrate the effect of polarized lenses?
-Use a polarizing lens plano. Do look at an object that reflects light (the window or the floor of the shop for example) through the lens. The reflections just disappear and your customer will realize immediately that the effect will get with his new pair of glasses.
panoply CR39 Polarized lenses can be more colorful?
-Si, the lenses may be colored. We recommend a temperature of 75 ° C for a period of time between 5 and 10 minutes. Please note that this process will not increase the coefficient of polarization of the lens color you want.
Polarized lenses stop UV rays?
-Yes, all polarized lenses stop UVA and UVB to 380 nanometers.
panoply CR39 Polarized lenses can be treated anti-glare?
-Yes, but you do not need AR coating both surfaces. Normally, we recommend to treat only the inner base of the lens. Instead treat the external surface is not recommended.
panoply CR39 Polarized lenses are scratch-resistant?
-Yes, but it is not necessary to treat the front surface scratch as it is made of hardened CR39.
YELLOW LIGHT AND DARK
lens ideal for sports fishing in low light: Perfect for early hours of the day and fishing after sunset. Delete the reflected rays of the 'water without attenuating light, making possible a correct vision of 'bait, the float of the bottom. Essential to 'opening of the fishing season because it allows an excellent visibility even on cloudy days and weather conditions. Especially appreciated in hunting, skeet shooting in the shooting or the 'arc where the perfect depth perception and field of target is critical.
YELLOW
polarization factor: 95%
lenses available in: Plano 71 mm., Plano addizzione FT28 with 74 mm. Monofocal 70 mm., Bifocal FT28 78 mm.
dark yellow is more versatile and can be used for fishing not only in low light conditions but also on sunny days on average. The 'intensive polarization allows a complete elimination of the reflected rays and a perfect view of the seabed and of the' bait. This color is especially appreciated by those who can fish for trout in the stream where alternating illuminated areas in shaded areas. YELLOW DARK
polarization factor: 99%
lenses available in: Plano 71 mm. monofocal and 70 mm.
We remind that in some parts of Northern Europe, the use of polarized lenses is prohibited in the practice of fishing. The explanation is simple: 'panoply use of polarized lenses, as well as making more comfortable vision, making it much more immediate localization of the fish, clearer vision of the seabed and allows Uina perfect fit of 'bait. This is why polarized lenses panoply invite all fishermen to implement the Catch and Release fish immediately captured.
