Ocular symptoms rise from smoking

Research showed that using e-cigarettes and cigarettes increased the likelihood of experiencing more severe and frequent ocular symptoms than users of a single tobacco product.   

A study conducted by researchers at McGill University in Canada and Stanford University in the US was published by JAMA Ophthalmology Journal and explored the impacts of cigarettes usage on ocular symptoms on 4,351 individuals aged 13 to 24 years.   

The most significant effects were seen in past seven-day dual users, who experienced severe itching, redness, dryness, glare, blurriness and headaches, while past 30-day dual users only had severe dryness, and frequent pain.
