Product information "CliP-ON PRiSMA anti-blue light glasses, bluelightprotect PRO - CP709". Blue light protection for glasses wearers, 99% maximum protection effect with PRO lenses.

Healthy eyes in modern times Modern flat screens (PC, TV, tablet, smartphone) emit light with a high content of short-wave blue light. Scientific studies have shown that this light can damage the retina of the eyes. Have you noticed that your eyes are sometimes red and burning after working for a long time in front of a computer? Light with a high blue light content strongly influences hormonal balance and can lead to sleep disturbances (disruption of melatonin production).

Watching TV at night without blue light protection increases stress and hormonal balance, so many of us can't fall asleep even at night, and regeneration is impaired.

Our filter goggles protect your eyes by filtering out the full content of the dangerous blue spectrum.

Which filter is right for you? PRO or Lite? This product: PRO filter lenses have the maximum blue light protection of 99%. Please note that the stronger tint PRO filter requires a longer adaptation period for color recognition than the lighter LiTE filter.

LiTE type lenses give you better color rendition with a shorter adjustment period than PRO, and are also suitable for watching TV, and are by definition recommended as a "filter for beginners". The protection against blue light is approximately 95%.

More information about screens and blue light It's time to protect your eyes!

Computer screens are not as harmless as people think. The flickers of frequencies that are barely perceptible to the naked eye and the large amount of optical and electromagnetic radiation obstruct our vision and are most likely detrimental to our eyes. Especially old TFT flat screens and radiating mercury frequencies as well as newer LED screens containing a high proportion of blue light.

This abnormal proportion of blue light not only causes more difficult vision, but also causes a damaging effect on the metabolic processes observed in scientific experiments on cells of the eye.

Specificities of existing models:

There are two lens filters available:

The "PRO" model for optimal protection at 99% against blue, however, light filtration is greater and color recognition is lower. The "LiTE" model provides slightly lower blue filtration at 95% but better color recognition.

More recently, the "EASY" filter has appeared. It filters at 90% and is used mainly by video game players or GAMERS. It impairs color recognition the least and has a higher light transmission while still protecting the retina very well.


The lenses are treated with an anti-reflective coating, to minimize unpleasant reflections.

PRiSMA® "CLiP-ON office pro" AR clip-on computer glasses



Here are the PRiSMA® "CLiP-ON office PRO" orange computer glasses.

The protection against blue radiation from artificial light is very high by the use of "CLiP-ON PRO" clips. The special dark amber colored lenses (a kind of orange which is not really orange) optimally filter the excessive proportion of blue light produced by the background lighting of computers with flat screens and other sources of blue light artificial lights such as fluorescent energy-saving lamps.

Why blue protection?

The risks of modern light

Mercury light present in old TFT screens or strong blue component in modern LED flat screens

The spectrum of natural light compared to energy-saving bulbs A potential danger to the retina Blue light prevents correct vision Hormone balance disorde To avoid chromatic aberrations and blurred vision No chance for eye regeneration! Adjusting the brightness of the screens offers no protection! Protect your eyes! The risks of modern ligh Due to their high proportion of red in the near infrared frequencies and their long wavelengths, our good old filament light bulbs were easy on our eyes. In contrast, new modern lighting sources based on mercury (compact fluorescent bulbs, old TFT screens) or cold white LEDs must be analyzed from a much more critical point of view. Light sources composed of mercury are found in the backlighting of TFT flat screens (old laptop screens and desktop computers), as well as in TFT television screens, energy-saving lamps and fluorescent tubes. . More recently, these are the backlights of modern screens and LED bulbs. The greatest disturbance to the eye is caused by modern flat screens in front of which adults and teenagers or children spend many hours a day during their working life. In addition to the electromagnetic fields given off by screens, fluorescent or LED lighting in the workplace contributes to increasing these negative effects. The only biocompatible light: halogen or filament bulbs. 230 volt dichroic halogen bulbs or 12 volt low voltage bulbs have been available for years. Today the production of harmful ultraviolet rays for the skin and the eyes are generally stopped by an anti U.V filter formed by a glass plate located in front. Some are even economical and class D with +- 30% energy savings and produce almost no blue light. For the eyes of people who work in front of flat screens and in professional premises, it is better to use these bulbs. In addition, these bulbs do not pollute the environment like compact fluorescent models which also contain mercury. A piece of advice if you are sick of energy savings, make at least a mixture of halogen and energy-saving bulbs in order to obtain the richest possible spectrum of light colors.

Blue light present in LED screens and LED bulbs

LED flat screens also emit a high proportion of blue light, especially light bulbs. It is especially the latter, in direct lighting in the eyes that must be avoided. Indirect lighting would present fewer problems. This light is suspected of producing disturbances in the internal biological clock (pineal gland) with metabolic and thymic consequences (mood disorders, depression, etc.), sleep/wake cycle disorders, etc. To this is added the fluctuations of light and of a large amplitude (flickering or stroboscopic effect) because of the very low persistence that they have. This is not perceptible by the eye but by the nervous system with indirect effects on health: epileptic seizures, reduced visual performance, stress, fatigue (source: A Review of the Literature on Light Flicker : Ergonomics, Biological Attributes, Potential Health Effects, and Methods in Which Some LED Lighting May Introduce Flicker, IEEE Standard P1789 (2010)).

Mercury light found in older TFT screens

The first flat screens used mercury light as a backlight. There are fewer and fewer of them, but there are still some. This light is as in the case of fluorescent tubes, produced by the gas discharge. While the spectrum of natural white light is composed of a harmonious proportion of colors, that of fluorescent lamps such as TFT screens radiate mercury light and have a discontinuous spectrum. This leads to a high natural proportion of blue color (blue, indigo, violet) with high energy amplitudes. However, the red zone, which is supposed to promote blood circulation, has little energy (see graph).

A danger for the retina?

A person doing screen work looks directly at the light source for a long time. Unfiltered and frequency-limited radiation disrupts normal vision and promotes pathologies of the macula (AMD-macular degeneration) also called "yellow spot" on the back wall of the eyeball where lutein is found. Lutein is present in high concentrations in the macula, a small area of the retina responsible for vision and visual acuity. Lutein is known to filter out blue light (UV) that attacks the photoreceptors in the eye, before it enters the tissue of the retina and macula. The lens filters out ultraviolet rays but not blue light. This proportion of blue light can, in the long term, lead to irreversible damage such as that observed in age-related macular degeneration (AMD), an incurable "yellow spot" disease. Numerous scientific studies on macular degeneration have proven that blue light can be harmful to the eyes. Oxygen radicals damage the metabolism of eye cells under the influence of blue light.

Blue light prevents vision!

Blue light shatters more easily than red light. By focusing on the different levels of perception of the eye we observe that long wavelength blue light produces chromatic aberrations and blurred visions. This is why pilots and athletes often wear yellow glasses because they filter the proportion of blue light, which increases visual acuity and sharpness of contrast. Often AMD patients get prescriptions for glasses with yellow lenses, to protect their macula from the destructive blue light.

Hormone balance disorders

Due to its high proportion of blue light and mercury, this light also affects hormonal balance in a negative way, reducing the production of melatonin and boosting the production of cortisol, stress hormones and ACTH . Disorders of hormonal balance can lead to diseases caused by civilization such as cardiovascular diseases, metabolic disorders, as well as immune system disorders, cancer, diabetes etc.


No chance for cell regeneration!

Near red light and near infrared we are able to activate cytochrome oxidases, enzymes important for the functioning of the mitochondria, the healing of wounds and which promotes the repair of damage caused to tissues at the scale cellular. If you spend most of the day in mercury-based light and then stare at computer screens for a long time, your eyes experience an overload of blue light. As this light does not have the proportions of red light and infrared light supposed to improve blood circulation, regeneration is often insufficient.

Brightness control offers no protection

Adjusting the brightness of a computer screen changes the modulation and pulse width of the light source at a certain frequency. When the brightness of the screen is reduced, the pauses between the pulses thus become longer, but the power of the pulses is not reduced. Therefore, the light pulse always penetrates the tissues of the organism at such a deep level, even when the eye perceives a lower luminosity produced by a change in the frequency modulation of the screen. In addition, it increases the pulsation of signals that can disturb the biological balance even more than permanent signals. The old TFT screens stop "flickering" only when they are illuminated at maximum intensity! This is why it is recommended to adjust the screens to the maximum and to wear special Prisma® computer protection goggles. For LED screens, the brightness must be adapted to reduce flickering, but ideally this is measured with a calibrated spectrometer and flickermeter. A specialist equipped with a good device can perform this measurement. 

Protect your eyes!
In order to protect the eyes from mechanical and chemical danger, it is necessary and normal to wear protective goggles. But the danger caused by unprotected work on screens and under fluorescent lamps is often minimized or denied by conventional medicine, although the mechanisms mentioned above and which are harmful have already been demonstrated in cellular experiments. Who wants to take risks and wait for all this to be definitively confirmed and recognized in a few years? Does conventional medical research provide all the definitive evidence? Is all the research independent when we know the economic stakes for the industry? If you ever want to protect yourself, today we recommend that you wear Prisma ® protective eyewear as a precaution.


Only high quality materials according to standards are used for all Prisma® CLiP-On lenses. All PRiSMA® glasses are CE certified and meet the requirements of all international standards.

All frames and lenses are impact resistant, durable and treated with an anti-reflective coating. The disturbances produced by light reflections are reduced, resulting in better contrast.

The glasses provide good UV protection with "UV-400" protection. These glasses are ideal as mid to low light level sunglasses.

Prisma® Clip-On models are the most suitable for fitting over classic optician glasses and are easy to install. They have a very practical flap mechanism, which allows quick lifting if necessary.

The types of glasses and the two orange or yellow filters can be used depending on the type of lighting and alternately if necessary. The user can define very easily which of the two filters to use according to his needs.

The dark amber (orange) "PRO" Clip-on is not legally accepted for use in cars in road traffic. The ideal for day and night driving is to choose the DRIVE NIGHT & DAY models

Cleaning and maintenance

Hot water with a little washing up liquid can be used. Dry with a soft cloth (like microfiber cloth) to avoid scratches. To avoid premature wear of lens treatment, do not use paper towels or other wood fiber products on lenses.


PRiSMA® lenses have a two-year warranty on material and workmanship. Regular use of glasses can produce very fine scratches on the lenses. This is normal wear and tear and does not warrant the warranty.
