Electronic cigarettes have negative effects on eye health
According to a recent American study, vaping could have harmful effects on the eyes. Several of the products present in the flavors and solvents of electronic cigarettes would be to blame.
The composition of the liquid contained in an electronic cigarette is far from trivial. “[T]These devices contain carcinogenic chemicals, air pollutants and heavy metals,” the researchers behind the study point out in the International Journal of Ophthalmology. “The purpose of this article is to shed light on the known effects of vaping on the ocular system. context”, continue the authors of the study.
To conduct the research, the experts collected their information from more than one million people between 2016 and 2018. Participants were asked to answer questions about their visual impairments and the frequency of e-cigarette use.
What were their findings? Two chemical components have been identified as being able to disturb the stability of the tear film which protects the part of the eye in contact with the outside. Additionally, the lipid layer, which protects tears from evaporation, can be damaged by vaping flavors. The researchers also noted that nicotine can interfere with light-adapted retinal vision. Finally, the study concluded that “vaping-related explosions, while unpredictable, can also lead to decreased visual acuity as well as long-term eye trauma.”
