Why Blue Light Is More Dangerous Than You May Believe

Take a moment to think about how many hours you spend in front of a computer or smartphone screen on a daily basis. Studies have found that the average individual will devote an incredible 1,700 hours interacting with a laptop computer on an annual basis. Perhaps more concerning is that fact that consumers spend just over three hours on their smartphone every day. While some of the health impacts associated with these behaviours (such as developing a more sedentary lifestyle) are obvious, others may be slightly more insidious. This is particularly the case when discussing the potential impacts of certain wavelengths of light.


Why Can Some Display Screens Negatively Impact Our Health?


It is first important to understand a specific wavelength that is known as “blue light“. This type of light is emitted by many modern screens as well as some smart lighting fixtures. The main concern is that the associated wavelengths may have a handful of unintended health consequences. Studies have found specific risks such as:


  • The possible disruption of nighttime sleeping patterns.
  • Lower levels of melatonin (a hormone related to sleep).
  • Mental and physical fatigue.
  • Headaches and eye strains.


The main problem here is that the majority of “smart” display screens emit this type of light. As it is nearly impossible to avoid, the chances are high that you are being exposed to excessive levels on a daily basis. Should you be experiencing any of the symptoms mentioned above, it is important to appreciate how these can be remedied. One effective measure is to wear a certain type of glasses.


What Solutions Can you Adopt?


The most obvious way to remedy the issues highlighted within the previous section is to limit the amount of time spent in front of electronic devices. Unfortunately, this is easier said than done. Perhaps your profession requires that you devote hours each day in front of a computer or you regularly speak with friends through the use of smartphone applications such as WhatsApp. In these situations, it could be wise to obtain a pair of computer glasses.


These specially engineered glasses are unique due to the fact that they are capable of blocking the majority of blue wavelengths emitted from common electronic devices. Thus, your eyes will be placed at much less of a risk. If you suffer from headaches or dry eyes, such options are likely to produce noticeable results within a relatively short period of time. These glasses can be obtained in a number of styles and designs; ideal if you are concerned about your appearance.


While the advent of modern computers and smartphones have ushered in a host of benefits, they are not without their potential drawbacks. The light emitted from these devices could be causing more harm than good over extended periods of time. This is why recognising the possible dangers as well as appreciating the viable remedies is important if you hope to find a reliable solution. After all, we are born with only a single pair of eyes!
