Blue light emitted by devices such as smartphones and laptops can be harmful.

The research team at Oregon State University conducted a study that revealed the damaging effects of blue light on the brain and eyes. The said study was published in the journal Aging and Mechanisms of Disease.

Researchers have chosen a fruit fly as their model in the experiment since their cellular and developmental components are the same as humans. Both humans and fruit flies are greatly affected when they are overexposed to blue light.

Adverse Effects of Blue Light

The researchers found out that the fruit flies exposed to blue light affected the eyes, specifically retinas and brain neurons during the study. Aside from this, the flies had trouble in their movements. These flies exposed daily to light and darkness for 12 hours were found to have a shorter lifespan.

Jadwiga Giebultowicz, a professor of integrative biology at OSU and one of the authors of the study, mentioned that the experiment results with flies only shows that the aging process is one of the many harmful effects of exposure to blue light.

She added that they had studied the spectrum of light to know what is harmful for the flies during their experiment. Their hypothesis proved that blue light is the reason for the flies’ shortened life span.

Natural Light Vs. Blue Light

Natural light plays a significant role in our bodies. It is responsible for helping activities in our brains, production of hormones and regeneration of cells. These processes are all essential for our development. 

When natural light gets disrupted by artificial light like blue light emitted from devices, this can cause sleeping and physiological problems. It was also revealed in a Harvard study that too much exposure to blue light could lead to diabetes and obesity.

Dealing With Blue Light Exposure

To avoid the harmful effects of blue light, Eileen Chow and Trevor Nash, co-authors of the study, have given their advice. Experts should make a healthier version of the light spectrum to help people improve their health.

The best option is to adjust the gadgets’ display settings. People who are extensively using their computers and smartphones can wear eyeglasses with amber lenses. These types of eyeglasses will help filter out the blue light.

For families, parents need to monitor the screentime of their children. Doing so will help lessen their exposure to blue light. To improve eye health, it is also good to take vitamin E. It has alpha-tocopherol that is known to protect eyes from blue light.

Using smartphones isn’t bad, as long as you know the consequences of having extended screentime.
