Sensitivity to light is a common complaint after a concussion. For some people, using smartphones, computers, and tablets can make their symptoms worse. Understanding how and why these devices affect your child’s symptoms can help you develop strategies to minimize adverse effects.
What is blue light and how does it affect my child?
Blue light is a type of visible light that can be found all around us. Blue light is emitted from LED light bulbs, fluorescent lights, as well as computer, tv and cell phone screens. Blue light can be problematic for individuals that have a sensitivity to light and can cause symptoms to worsen after a concussion. Blue light can also affect sleep which is important for recovering after a concussion.
Does the brightness of the screen matter?
Yes! Screens that are too bright, too dark, and/or viewing a bright screen in a dark room can increase eye strain and headaches. Make sure to adjust screen brightness to the brightness of the room they are in; it will help avoid making your child's symptoms worse.
Screen distance also matters! Holding their cell phone too close to their face or staring at screen for too long can also cause eye strain and make your child’s symptoms worse. If your child has a cell phone, use the screen distance feature, otherwise, use the 20-20-20 rule – for every 20 minutes your child is looking at a screen, have them look at an object at least 20 feet away for 20 seconds.
Concussion symptoms are unique to each individual, but there are common symptoms you should be aware of.
If you believe your child has a traumatic brain injury or concussion, call your child's doctor immediately.
We understand as a parent you might have a lot of questions around brain injuries. How do I know how severe the brain injury is? When can my child return to sports? How can I make sure they recover safely?
