Digital Eye Strain Is Becoming More Prevalent Among Our Tech-Savvy Population
As the name implies, digital eye strain is the direct result of how we use the digital displays on our laptops, computers, tablets, and smartphones. These devices, which we use outside of how our eyes naturally evolved, can cause a range of symptoms that range from mild to challenging.
What Causes Digital Eye Strain?
Digital eye strain is caused by the combination of factors.
Our Eyes’ Ideal Focal Point
Our eyes evolved to have an ideal focal point of roughly 31” in front of you. This is the point where our eyes see at their natural best. When using smartphones or sitting at the computer, the displays are often well inside this 31” area- this causes our eye focusing muscles to have to work harder.
Too Much Concentration Creates Eye Fatigue
Our eyes are not designed to focus on a single point for prolonged periods of time. This is why we can experience eye fatigue when reading, watching TV, or working at the computer.
High-energy light (HEL), which we see as blue light, is a spectrum of light that includes ultraviolet light (mostly received from the Sun). Studies have shown that HEL can negatively impact our natural sleep cycle as well as our eye and retina.
