![]() ![]() Even if it’s a particularly long photo shoot, there are small breaks in between shots and flashes. While there is some disparity here, we know that camera flashes don’t last for 30 seconds, let alone 100 seconds. Some studies show it takes around 100 seconds of looking at bright light for permanent damage to be done to the retina, while other sources suggest the limit is around 30 seconds. Even if someone took ten flash photos of you in a row, there would be no damage. As most camera flashes last for just 1/400 th of a second (although it might feel like a lot longer!), our exposure to the flash is very small. This is due to three main factors: exposure, intensity, and focus. ![]() Ultimately, yes, a camera’s flash is very safe for our eyes. Thankfully, we tend not to experience photo flash all that often, however we do see a lot of blue light in other forms like mobile phone screens or televisions. Frequent exposure to blue light is said to cause irreversible loss of retinal cells and reduce your overall visual sharpness. ![]() LED lighting emits blue light which has been found to increase your risk of developing age-related macular degeneration (AMD). The amount of light produced, and the length of the flash, can be altered by the photographer, depending on the kind of lighting they require for their shoot. Most modern day flashes use relatively low wattage LED bulbs. It’s a short burst of light, usually lasting 1/400 th of a second, and is used to light up an area, improving the brightness of a photo taken there. What if we stood really close to the flash? What if we took ten flash photos in a row? Is it worse for babies and children with still-developing eyes? We’ll delve into all these questions and discover some truths surrounding the impacts of photo flash.įirst, let’s start by talking about what photo flash is. With those little temporary blind spots in our vision, it’s easy to believe that photo flash must be causing some level of damage to our eyes. Then, when it does eventually happen, we’ve all been momentarily blinded by the flash – particularly if it’s a dark environment – and have had those green and purple spots float around in our vision for the next five minutes. We’ve all been in front of the camera with a cheesy grin fixed to our faces, waiting to hear the shutter click and the camera flash. What are the lasting impacts of photo flash? ![]()
