1. What is a Kensington Eyesafe® Blue Light Privacy Screen Filter and how does it work?

Kensington privacy screens use microlouver technology to block side views, keeping on-screen information visible only to the person directly in front. Integrated Eyesafe® RPF60 technology filters high-energy blue light (435–440 nm)—the range most associated with visual discomfort and long-term retinal health.

2. What are the benefits of a privacy screen with Eyesafe® Technology?

You get two levels of protection: data privacy and enhanced blue light filtration for visual comfort. The screen also helps reduce glare and protects your device from scratches and smudges. Eyesafe® RPF60 filters up to 60% of high-energy blue light (435–440 nm) to support eye comfort throughout the day.

3. Why is blue light a concern?

Prolonged exposure to certain blue light wavelengths may contribute to eye discomfort and interfere with natural sleep rhythms. Filtering blue light helps support visual comfort, sleep quality, and overall wellbeing.

4. Can this product reduce eye fatigue?

Users report improved comfort during long hours of screen time when using products with Eyesafe® Technology. Anti-glare features also help minimize strain from harsh reflections and ambient lighting. Results may vary, please consult a medical professional if you are experiencing symptoms.

5. How is this different from other privacy screens?

Most privacy screens focus solely on data protection. Kensington’s version also filters blue light for added eye comfort—combining privacy while enhancing user comfort throughout the day in one product.

6. Is the blue light filtering backed by research?

Yes. Eyesafe® technology is developed with guidance from medical experts and supported by scientific research. It meets UL Solutions’ verified requirements for blue light filtration and color performance.

7. Will it affect screen brightness or color?

Privacy screens may slightly reduce brightness. However, Eyesafe® Technology is designed to maintain screen clarity and color accuracy—without the yellow tint found in many blue light filters and software-based solutions.

8. Will this screen fit my device?

Kensington offers privacy screens in various sizes for laptops and monitors. Use our privacy screen product finder tool to search our database by make and model of your device and you’ll be presented with a range of compatible options.

9. Is it easy to install and remove?

Yes. Each screen includes adhesive tabs for flexible installation—use it as a semi-permanent fixture or remove it when needed.

What is Blue Light?

Blue light, also known as high-energy visible (HEV) light, is a color in the visible light spectrum that can be seen by human eyes. These wavelengths of visible and non-visible light are measured in nanometers (nm), and, in general, the shorter the wavelength, the higher the energy. Blue light is a short wavelength, which means it produces higher amounts of energy.

Unlike other forms of light, the eyes cannot effectively filter blue light, so more can pass through the eye to the retina.*

Sources of Blue Light

We are exposed to blue light on a near constant basis. The largest source of blue light is sunlight, but it is also emitted by laptops and computer monitors, smartphones, tablets, TV, fluorescent and CFL bulbs.

Our blue light exposure from digital devices are of particular concern because of the close proximity of the screens, length of time we use our devices, and the cumulative impact of using devices every day.

Benefits of Blue Light

Moderate amounts of blue light is essential for good health. Exposure to blue light offers several benefits. It promotes alertness, helping individuals stay focused and attentive throughout the day. Additionally, blue light boosts memory and cognitive function, enhancing information retention and mental clarity. It also elevates mood by stimulating the production of serotonin, a neurotransmitter associated with happiness and well-being. Furthermore, blue light plays a crucial role in regulating the body's circadian rhythm, ensuring a healthy sleep-wake cycle and better sleep quality.

Concerns about Blue Light

Screen time and blue light exposure have been raised as a growing public health concern. Doctors, educators, employers and parents agree that there are potential risks from overexposure. According to a recent survey, doctors believe the following are symptoms of excessive screen time and blue light exposure.

Eyes and Body

Screen time has been on the rise for the last 20 years and is now exceeding 11 hours per day.* According to the Vision Council, many people experience eye discomfort and vision problems when using digital devices for extended periods. Potential symptoms of digital eye strain may include:

Eye strain
Blurred vision
Dry, irritated eyes
Headaches

* Eyesafe® estimate based on Nielsen Total Audience Reports, 2018-2023, US. Some amounts of simultaneous usage may occur across devices

Sleep

The use of digital devices at night may suppress the release of melatonin, the hormone responsible for making us feel drowsy. Too much blue light exposure from viewing screens at night may result in: *

Trouble sleeping
Waking up during the night
Reduced alertness the next day

* Chang AM, et al. Evening use of light-emitting eReaders negatively affects sleep, circadian timing, and next-morning alertness. Proceedings of the National Academy of Sciences of the United States (PNAS). January 2015. 112(4): 1232-1237.

Long-Term

There is evidence that the eye is susceptible to blue light exposure, and that over a period of time, cumulative exposure may increase the likelihood of vision problems. More research is needed to ascertain long-term impacts to the retina and any links to chronic vision problems.

Standard Privacy Screen Features

Limited Viewing Angle

Narrows the field of vision on the screen to +/- 30 degrees, helping you keep the information on your screen private and reducing the chances of a visual data breach, which is important both in the office or in a public setting.

Installation Options

The privacy screen can be mounted either with the included frameless tab holders that attach to the edges of your monitor, letting you quickly and easily insert or remove the privacy screen, or you can mount it with double-sided tape that adheres directly to the screen for a cleaner look.

Anti-Reflective Coating

Reduces glare from any outside light sources that can interfere with your viewing clarity.

Reversible Viewing

One side has a matte finish to reduce glare and fingerprints. The other side is glossy and provides a clearer view of the monitor. The anti-glare/matte surface uses a special antimicrobial film coating that prevents mildew and bacteria growth, which can cause stains and odors on the film.

Scratch Resistant

A resilient, scratch-resistant surface* that can withstand contact with something as hard as a 2H-grade lead pencil, ensuring increased durability and protection.

Military-Grade Protection

Meets wipe down (MIL-STD-810H Method 504.3 Contamination by Fluids) testing standards.

Kensington privacy screen limits viewing angle, narrowing the field of vision to 30 degrees.
