![]() The wavelength with the highest intensity was 450 nm. The arrow points to the distribution correlating with blue light which ranges from 420 nm to 490 nm. Two images from the spectrometer software that show intensity for each wavelength in nanometers. The present study aims to determine the efficacy of a blue light-blocking screen protector on three handheld devices (iPhone 8, iPhone X, and iPad 9.7”) in reducing blue light intensity. A practical advantage of using blue light-blocking screen protectors over applications like NS is the preservation of normal colors on the screen, while the latter tints the display color orange-red. Alternatively, smartphone applications are available that claim to block blue light emitted from electronic devices, such as night shift (NS) in Apple Inc. A recent systematic review evaluating the efficacy of blue light-blocking spectacle lenses on visual performance, macular health, and the sleep-wake cycle found that there is currently no high-quality evidence supporting their advantage. These include blue light-blocking glasses, intraocular lenses, and screen protectors (adherent glass over the display of smartphones and tablets). Potential negative health outcomes associated with blue light exposure have led to the development and marketing of products that claim to block it. Blue and visible light exposure can also potentially contribute to age-related macular degeneration however, results are mixed and inconclusive because various factors can play a role in the development of this disease. Exposure to digital displays can suppress melatonin levels and modulate sleep. Intrinsically photosensitive retinal ganglion cells, which express melanopsin and are maximally sensitive to blue light, regulate nonvisual physiological responses such as circadian clock, sleep, and melatonin suppression. Cultured human retinal pigment epithelial (RPE) cells are also susceptible to phototoxicity from visible light in a wavelength-dependent manner.Īlthough the intensity of blue light emitted from electronic devices is much lower than from daylight, there is evidence that even at low intensity, artificial blue light from digital devices can cause oxidative damage to human RPEs in vitro. Phototoxicity of short-wavelength light (400–500 nm) to the retina of animal models, such as rats and monkeys, has been well established for many years. Your order will reach your doorstep within 72 hours.With near-ubiquitous use of high-intensity light-emitting diodes in artificial lighting and backlit displays of smartphones, tablets, and computers, the human eye is becoming increasingly exposed to blue light beyond what is found in ambient daylight. ![]() Place your order online or call our customer support representative. also has a 3M screen projector for your computer. Privacy filter screen protectors come with anti-glare protection, and thus help your eyes to strain less in prolonged use of computer or lappropriateop. In fact, you might want these protectors to fill out personal forms, credit card details, or to create unique work which you don't want to share it with outsiders. A privacy filter is perfect for you to view business information for your computer or lappropriateop if the matter in it is sensitive. Privacy filter screen protectors disguise the screen in such a way that you can only the screen if you are sitting straight in front of the screen, and views from any other angle will be restricted. This can be easily achieved with privacy filter screen protectors. ![]() ![]() ![]() Screen Protectors - Get Privacy Screens & Protectors OnlineĪt your workplace or home, you need privacy for the work you are doing. ![]()
