An unhealthy lifestyle translates into many health problems.

Smoking, binge drinking and illicit drug use are known to cause cancer, diabetes, heart disease, lung damage, stroke and death. They can also lead to serious eye problems.

Cigarette smoking remains a major health issue despite of years of health warnings and public awareness campaigns.

Smoking has been linked to early development of macular degeneration and cataracts.

Compared to non-smokers, people who smoke a pack or more per day are two-to-three times more likely to develop macular degeneration an aging condition in the retina, affecting the central vision.

The inhaled substances in cigarette smoke constrict the blood vessels and promote blood clot formation in the retina and optic nerves.

Partial to almost complete blindness happens when there is thrombosis, or blood clot, in the central retinal artery, which is the main artery that supplies blood, oxygen and nutrients to the retina.

Smoking increases the risk of ischemia, or stroke, in the optic nerve, which transmits the images from the eye to the brain, resulting significant permanent visual loss.

About one-in-six adult Americans binge drinks about four times a month, consuming about eight drinks each time.

There is a well-established linkage between Type 2 diabetes and excessive alcohol consumption.

The most serious ocular complications of diabetes is diabetic retinopathy. The diabetes-damaged retina develops hemorrhages and swelling, resulting in visual loss.

Alcohol abuse increases the incidence of early onset of cataracts and macular degeneration.

Methanol, or wood alcohol, in contaminated moonshine damages the optic nerve, and if untreated,the person will suffer partial to total blindness.

Ocular trauma with visual loss is too often seen with alcohol intoxication.

Illegal substance abuse is at the extreme end of vices.

It is estimated about 10 percent of adults use illegal drugs.

There are many deleterious effects to the eyes.

Intranasal cocaine use is particularly damaging and potentially leading to acute attack of angle closure glaucoma, retinal hemorrhages and optic nerve damage.

Smoking crack cocaine is associated with infection and diminished blood flow to the retina.

Methamphetamine use is known to cause infection in the cornea which is the transparent tissue in front of the eye.

Retinal inflammation is also seen in methamphetamine use.

Intravenous drug abuse introduces infection to the eyes and particles clotting the blood vessels in the retina and the optic nerve.

Many people assume their vices will get their eyes red and eyelids droopy.

In fact, they can suffer from many sight threatening complications.

Hopefully, this will motivatethem to give up their vices and adopt healthy habits.
