Screen protector purchase tips: Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss. Although more research is needed to determine how much natural and man-made blue light is “too much blue light” for the retina, many eye care providers are concerned that the added blue light exposure from computer screens, smartphones and other digital devices might increase a person’s risk of macular degeneration later in life.

You may be wondering why using a computer is so much harder on your eyes than reading printed materials like a book or magazine. The main reason is that when we stare at computer screens, we tend to blink less. In fact, while focusing on digital displays, a person’s blink rate can be reduced by a third to a half, which causes their eyes to dry out. Additionally, many of us are not viewing these screens from the optimal distance. In recent years, a popular solution to this problem has been blue light filters; namely, expensive computer glasses. However, these glasses, as well as other blue light filters, are no more effective at reducing the symptoms of eye strain than a neutral filter. Instead of spending money on something that may not help, try these simple and effective tips first.
