Toxins in e-cigarettes can damage users’ eyesight, a new study suggests.
Around 2.7 million people in the UK use the device, often as an alternative to smoking after quitting the habit.
The UK’s chief medical officer is encouraging smokers to switch to vaping, saying it’s much safer and better than smoking.
Smoking is known to damage the eyes, as well as being a leading cause of cancer and countless other diseases deadly disease.
Now, scientists say people who use e-cigarettes may also have an increased risk of vision problems.
Current testers were 34% more likely to have visual impairment than those who had never tried it, and former paperworkers were 14% more likely to have vision impairment.
The new University of California study included 1,173,646 US adults between the ages of 18 and 50, walkie talkie report.
Participants were asked if they had ever smoked or smoked and were asked if they had impaired vision.
The findings, published in the American Journal of Ophthalmology, add to others who say e-cigarette use is not without some risk.
E-cigarettes work by heating a liquid, usually fruit-flavored, that contains nicotine, the addictive substance of tobacco.
It also contains propylene glycol, glycerin, flavorings, and other chemicals that research could potentially be harmful, but to a significantly lesser extent than tobacco.
Scientists theorize that ingredients like propylene glycol in vaping liquids create free radicals — cell-damaging atoms that can weaken the fluid that coats the surface of the eye.
It may also promote oxidative stress, a major factor in the development of chronic diseases as well as cataracts and glaucoma.
Research shows that smoking increases the risk of certain eye diseases such as age-related macular degeneration.
But it’s important to note that at this point, it’s unclear whether those risks are related to vaping or something else.
Professor Simon Capewell, a clinical epidemiologist at the University of Liverpool, said the latest California study had failed to prove a link between vaping and eye damage.
But he said “there are many nasty toxins in the e-cig vapor”.
There have been plenty of warnings about using e-cigarettes – such as a recent finding that it can increase rates of erectile dysfunction and stroke in middle age.
The World Health Organization states they “increase the risk of heart disease and lung disorders” and are “particularly risky when used by adolescents”.
But there is growing evidence that these devices can effectively help people kick the killer smoking habit.
The NHS says: “They’re not completely risk-free, but they carry a small fraction of the risk of tobacco.
“E-cigarettes do not produce tar or carbon monoxide, two of the most harmful elements in smoke.
“Liquids and vapors contain some of the potentially harmful chemicals that are also found in tobacco smoke, but at much lower levels.”
E-cigs can help you control your nicotine cravings, and a 2019 study found that people who use them with direct support are twice as likely to quit smoking.
According to a report from Public Health England in February 2021, around 6% of adults vape.
Some of them are never smokers before, although this is strongly encouraged.
The report says nearly 30% of 11 to 18 year olds have tried vaping products but have never tried smoking.
There is concern that the sweet taste of vape products is attracting young people to use them, when they may not have tried a cigarette.
The Committee on Toxicology of Chemicals in Food, Consumer Products and the Environment, an independent body that advises the UK Government, reported in 2020 that non-smokers who use vaping could have to deal with avoidable harm.
But the UK Health and Security Service (UKHSA), which has replaced PHE, says there is “no evidence to support concern that e-cigarettes are increasing the number of smokers”. .
Meanwhile, smoking rates among young adults and adults in the UK continue to fall.
Britain could be the first country in the world to offer prescription e-cigs to people trying to quit, it was revealed in October.
