“…Delayed sleep phase seems to be increasing, especially among teen-age students and young adults, and seems partly due to increasing use of television, computers, cell phones and tablets late in the evening. It is thought that the strong blue-light radiation of many display screens used in the evening exacerbates delays of circadian rhythms (6,7).…”

“…Previous study protocols administered continuous screen use for 1-5 h (Cajochen et al, 2011;Heath et al, 2014;Chang et al, 2015;van der Lely et al, 2015) when investigating circadian phase shifts due to screen use. Wood et al (2013) found measurable melatonin suppression after 2 h of tablet use.…”

“…They could not find sound proof that 1 h of tablet screen had a significant impact on the circadian phase. van der Lely et al (2015) investigated the effect of blue light-blocking glasses on the circadian phase. In 13 young males who spent 3 h prior to going to bed in front of a computer screen for 1 week each, they found a significant increase in melatonin when using blue light-blocking glasses.…”

Computer Screen Use Detection Using Smart Eyeglasses

Screen use can influence the circadian phase and cause eye strain. Smart eyeglasses with an integrated color light sensor can detect screen use. We present a screen use detection approach based on a light sensor embedded into the bridge of smart eyeglasses. By calculating the light intensity at the user's eyes for different screens and content types, we found only computer screens to have a significant impact on the circadian phase. Our screen use detection is based on ratios between color channels and used a linear support vector machine to detect screen use. We validated our detection approach in three studies. A test bench was built to detect screen use under different ambient light sources and intensities in a controlled environment. In a lab study, we evaluated recognition performance for different ambient light intensities. By using participant-independent models, we achieved an ROC AUC above 0.9 for ambient light intensities below 200 lx. In a study of typical ADLs, screen use was detected with an average ROC AUC of 0.83 assuming screen use for 30% of the time.

“…Both, hardware filters and software applications were recently compared [15]. A recent work has investigated the use or orange-tinted blue blocker therapeutic lenses to reduce the effects of LED illuminated screens on evening users of these devices [16]. Finally, several ophthalmic lens manufacturers have introduced in the market innovative ophthalmic lenses incorporating blue light filters.…”

ABSTRACT:As a result of the recent improvement in light-emitting diode (LED) technology, the displays of the vast majority of electronic devices are now illuminated by LEDs. There are several advantages of this type of light source over its predecessors; however, recent research is giving support to the fact that prolonged exposition to the white LEDs emission in the blue spectrum may have a negative impact on visual health, as well as, on biological rhythms (circadian rhythms). As a consequence, ophthalmic lens manufacturers have recently introduced in the market innovative lenses that incorporate blue light filters, especially designed for electronic device users. In this work, the performance of different blue light filters present on commercially available ophthalmic lenses was tested and compared. Lenses were placed in front of a LED-based backlight tablet, in a similar way a common user would be reading a text on the electronic device. The absorption characteristics of the various samples from four different ophthalmic lens manufacturers were measured. Analysis of the different samples from the same manufacturer was conducted and blue light filters from different manufacturers were compared.Key words: Blue light filters, ophthalmic lenses, LED backlight screens, electronic devices, circadian rhythm RESUMEN:Como resultado de las mejoras en la tecnología LED (del inglés, light-emitting diode), las pantallas de la mayoría de dispositivos electrónicos actuales están iluminadas por LEDs. Muchas son las ventajas de esta fuente de luz sobre las fuentes predecesoras; sin embargo, algunas investigaciones recientes han puesto de manifiesto el hecho que la exposición prolongada a la emisión en la zona azul del espectro de los LEDs blancos puede tener un efecto negativo en la salud visual y en los ritmos biológicos (ritmos circadianos). Como consecuencia de ello, los fabricantes de lentes oftálmicas han introducido recientemente en el mercado lentes innovadoras que incorporan filtros de luz azul, especialmente diseñadas para los usuarios de dispositivos electrónicos. En este trabajo, se evaluaron y compararon diferentes filtros de luz azul en lentes oftálmicas comerciales. Se disponían las lentes frente a una tableta retro-iluminada con LEDs, de manera similar a como un usuario se situaría delante del dispositivo electrónico para leer un texto. Se analizó la capacidad de absorción de varias muestras de un mismo fabricante, y se comparó el resultado entre filtros azules de distintas marcas comerciales. [5] M. Argilés, G. Cardona, E.
