A polarizing filter is a thin film inside the lens that blocks various kinds of harmful light
—UV rays, glare, and 'noisy light'.
Coloring the polarizing filter enhances its effectiveness by reducing the amount of light entering the filter.
Generally, dichroic pigments are used as the raw material for coloring polarizing filters.
But dichroic pigments in lens filters have inherent limitations: If the polarizing film color is too dark, clarity of vision is reduced.
If the polarizing film color is too light, the filter's ability to block out 'noisy light' is reduced.
Dichroic pigments can also reveal an unnatural reddish discoloration, called 'red light transmittance'.
Our solution at TALEX is to use iodine compounds as the raw material for our original 'noisy light-cutting filter'. This produces a filter that's brighter and clearer, with higher polarizing performance, and no 'red light transmittance'. The super-thin 0.03 mm iodine-dyed filter is directly laminated between two optically pure lenses, providing crystal-clear vision—with no 'noisy light', no discoloration, and no distortion—a truly 'eye-friendly' experience.
In the atmosphere there are various pollutants like dust, pollen and other particles that cause breathing problems.
In tap water there are also pollutants like residual chlorine and THMs, which make the water impure.
In light also, there are harmful components like UV rays and reflected glare
from various surfaces-'noisy light'-which come into direct contact with the eyes,
and can actually increase stress hormones.
TALEX's original polarizing filter is dubbed 'the light purifier' for its ability to effectively remove only the harmful components from the light. It's just like an 'air purifier' for the atmosphere or a 'water purifier' for tap water. With the current increase in eye disorders such as cataracts, astigmatism, etc., the 'noisy light-cutting filter' has attracted great attention in many eye-related fields. The 'light-purifying' capability of our original 'noisy light-cutting filter' is the quickest and surest way to protect your eyes from harmful, 'noisy light'.
To take full advantage of the efficacy of our original
'noisy light-cutting filter' technology,
we have continuously sought for
and developed new and original lens materials.
Even though new cheap and easy-to-handle materials have been introduced by some chemical companies, we have found their filtering performance is not up to our standards, and deemed them unsuitable for use in our polarized lenses.
We use only materials that will enhance the experience of seeing.
Our polarized glass lenses were developed in 1966.
A high-performance polarizing filter and special glass lens wafers combine to produce a polarized lens of superior optical quality.
The GPL66 lens shows excellent scratch resistance and clarity.
Our polarized plastic lenses were developed in 1975.
Our unique monomer casting method enables the PPL75 lens to maintain superior optical quality.
The PPL75 lens is much lighter than glass, yet maintains absolute clarity with no distortion.
Our polarized CACCHU lenses were developed in 2000.
Although polycarbonate is well known for its impact resistance, its poor optical quality and distortion are not up to our standards. Only a lens material that is light, strong and optically superb will serve for our polarized lenses.
That material is CACCHU. 'KACCHU' is the name of the protective armor worn by Japanese Samurai. It is an apt description for this amazing new material. CACCHU is extremely light, with the density of 1.15 g/cm3-passing the ANSI Z87.1 standard, the strictest in the world for protective eyewear. It is also incredibly strong -the perfect material for use in protective lenses. Its optical quality is excellent, rivaling even that of our pristine PPL75 lenses.
The CACCHU lens received the Japanese 'Good Design Award' in 2006 for its amazing performance.
