GLASSES FOR USE ON COMPUTERS

Blue and violet light blocking solutions

These glasses feature a treatment developed specifically for those who spend a lot of time indoors and are exposed to the blue-violet light from LEDs and television, computer or tablet screens.

Design

It reflects parts of the blue-violet light emitted by digital sources, preventing the light from entering the eye .

The treatment reduces transmission in the 380-455 nm spectrum (blue light hazard), while maintaining a high level of transmission above 460 nm.

Blue-violet light is everywhere, although its intensity varies greatly .

While an LCD monitor produces a brightness of 250 cd/m2, the clear blue sky at midday is 32 times brighter. Direct sunlight can be thousands of times brighter.

Blue-violet light blocking requirements .

Exposure to harmful blue-violet light varies greatly between indoor and outdoor settings. It is important to have the proper blue-violet light blocking depending on its intensity.

Advantages

• Computer glasses respond to the visual health of users with blue-violet light blocking solutions.
• The lenses are designed to block different intensity levels of harmful blue-violet light in indoor and outdoor activities.

BLUE LIGHT

A new challenge for the digital world

Light plays a fundamental role in our vision and in every facet of our lives. For thousands of years, humans relied primarily on a single source of illumination: the Sun.

Natural sunlight significantly influences a person's body, mind, health and overall sense of well-being. However, today, artificial light sources play an increasingly important role in our daily lives. Rooms are brightly lit even during the day and we are almost always staring at all kinds of screens. From LED screens and halogen lights to tablets, smartphones, TVs and similar devices, all of these lighting sources have one thing in common: they emit high levels of blue light.

What is the truth about blue light in the digital world? What do we know about the effects of this truth?

Blue light and our vision

Smartphones, computers, tablets, flat-screen TVs and the new smart watches, along with all their displays, alter the influence that light has on us because, like fluorescent lamps, energy-saving bulbs and LEDs, they all emit intense blue light. This means that we are exposed to blue light practically all the time, during the day, evening and night. What are the consequences?

The truth is that blue light hits the retina at the back of the eye, and scientific studies and laboratory analyses have shown that too much blue light can damage the retina. At worst, blue light can lead to muscle degeneration and permanent vision loss. However, more scientific studies are needed to learn more about the level of blue light needed to damage the eyes and to determine limits or at least recommended levels of exposure to blue light.

Are you having trouble sleeping because of your mobile phone or laptop?

Light helps regulate our biological clock and is therefore proven to influence a person's sleep-wake cycle. Blue light in the early evening notifies the body that it should stay awake , while light in the early morning tells it that it is time to wake up.

The hormone melatonin plays a central role in this process. During the day, we have reduced levels of melatonin in the body. When bright light hits the eye, it directly influences the production and expenditure of melatonin, which is generally recognized as the sleep hormone.

When exposed to blue light, special receptors in the eye communicate that it should release less melatonin, which keeps us alert and awake. Reducing blue light levels in the evening encourages more melatonin release, which causes a feeling of sleepiness and tiredness.

What steps can I take to limit the effects of excessive blue light?

When you stare at a computer screen or other digital device, you expose your eyes to high levels of blue light, which causes, among other things, a reduction in contrast sensitivity. Staring at a screen can also cause eye strain, contributing to eye strain due to digital device use or computer vision syndrome.

Ophthalmic lenses can help protect your eyes from blue light thanks to a special filter that makes working on your computer screen and using digital devices easier.
