Found out one more terrible harm of smoking, the cigarette must not ignore

Experts warn that cigarettes are directly related to the two leading causes of blindness, cataracts and age-related macular degeneration. In addition, smoking causes many other eye diseases.

According to doctors, cigarettes (such as pipe tobacco or cigar) also contain more than 4,000 different highly active substances such as tar, compounds of hydrocarbons, formaldehyde, carbon monoxide and heavy metals and so on. The damage of tobacco to the lung and heart is too obvious. However, the harm to the eyes is less known.

According to many studies, tobacco is directly related to the two leading causes of blindness, cataracts and age-related macular degeneration. In fact, there are many studies confirming that cigarettes as a cause or a contributing factor to some other eye disease.

Smokers are at risk of macular degeneration 2-4 times higher than non-smokers. Toxic factors in cigarettes damage the blood-retained barrier and reduce blood flow to the retinal tissue, contributing to macular degeneration- one of the two leading causes of blindness in elderly over the age of 60, only after cataracts.

Smokers is hot and dry with many stimulants also cause conjunctivitis or chronic lashes. Tears are more volatile due to hot smoke that will cause dry eyes.

All patients with uveitis, including those with marked elevations in the eye, have a higher incidence of recurrence, a risk of chronic transmission if smoking is maintained. By reducing the blood supply to nerve tissues, smoking exacerbates the diabetic retinopathy, causing neurological anemia.

Pregnant women who smoke make their future children at risk ofmeningitis due to bacteria that is five times as much as other people. Blind meningitis is not uncommon. In addition, the prevalence of premature, low-birth-weight babies in smokers contributes to children with ROP getting a high risk of blindness.

According to the WHO, about 6 million people die every year due to 17 types of cancer that are thought to be related to smoking.

Professor David Phillips of the Royal College London, UK, said that this is the first time scientists put the startling data on the effects of secondhand smoke on our genetic data. Secondhand smoking not only makes the gene mutate in the lungs, but also other parts of the body are affected by its effect because the substance causing disease in the smoke is seen in almost organ contacting with smoke.
