Scholar: Study Shows ‘No Link’ Between Vapor, Eye Damage

The new study by the University of California found that vaping could cause some eyesight impairments. The study included 1,173,646 adults in the US aged between 18 and 50, according to the The Telegraph. At least one researcher, however, says the study doesn’t correlate vaping and eyesight damage.

Current vapers were 34 percent more likely to suffer from visual impairments compared to those who had never tried it, and former vapers 14 percent more likely to suffer impairments, according to the study.

Participants were asked if they ever have smoked or vaped and asked if they had suffered visual impairment. The findings, published in the American Journal of Ophthalmology, found that vaping may also promote oxidative stress, a key factor in the development of chronic diseases as well as cataracts and glaucoma.

Simon Capewell, a professor and clinical epidemiologist at the University of Liverpool, said the latest California study did not prove a link between vaping and eye damage. But he said there are “many nasty toxins” in e-cigarette vapor.

“But it is important to note that at this point, it’s unclear whether those risks are connected to vaping or something else,” the story states.

The eyesight study follows a recent study that found that vaping caused erectile disfunction. That study was also found to be flawed.

A major issue with the ED study is that participants were classified as current someday (“i.e., not every day or occasional”) or daily vapers, or smokers if they consumed cigarettes “every day or some days.” Beyond this self-reported information, the researchers didn’t know how much or which e-liquids the vapers in their study used, nor did they know how many cigarettes each smoker consumed.
