Substance abuse can cause physical and mental health problems. While drugs; such as alcohol, marijuana, and cocaine; may give a person temporary pleasure, they can cause long-term consequences, including deteriorated eye health. Substance abuse affects vision in many ways.

One of the most common problems caused by substance abuse is an increased risk of developing glaucoma. Glaucoma is a condition where the pressure in the eye is greater than normal, which can damage the optic nerve and eventually cause blindness. Substance abusers are more than twice as likely to develop glaucoma as those who don’t abuse drugs. Alcohol in particular can contribute to glaucoma because it increases eye pressure and impairs the circulation of fluid in the eye. Substance abuse is also linked with a higher risk of retinopathy, a condition causing damage to the retina. Many drugs of abuse, including marijuana and cocaine, can decrease blood pressure leading to retinal damage.

Substance abuse can also increase the risk of developing eye infections. Drugs that are injected have the potential to cause infection of the eyes due to the introduction of bacteria and other microorganisms in the bloodstream. Infections in the eye can be caused by bacteria, fungi, or viruses, leaving the eyes red, painful, and potentially blinding if not treated promptly.

In addition to physical problems, substance abuse can damage vision in other ways. The abuse of drugs can lead to impaired focus, impaired memory, and trouble recalling information, all of which are poor vision skills. Substance abuse can also lead to an inability to accurately interpret visual information; a characteristic known as impaired visuospatial ability. People who use drugs may also have difficulty following instructions, which affects their ability to properly operate equipment or drive safely.

Substance abuse can also contribute to mental health problems, which can further exacerbate eye health issues. Mental health issues can lead to an overall increased risk of developing eye diseases and impairments. Drug use, in particular, can lead to depression and anxiety, both of which have been linked to impaired vision.

Unfortunately, the effects of substance abuse on eye health can be irreversible. Some medications or medical procedures can help slow the progression of certain eye diseases, but the damage often cannot be undone completely. This means it is essential to take steps to prevent substance abuse in order to minimize damage and reduce the risk of vision problems. Quitting an addiction is not easy without help and support, but various resources exist to help individuals get the help they need.

Overall, substance abuse can cause numerous physical and mental health problems, including a deteriorated eye health. If left untreated, eye health could potentially cause permanent damage, so it is important to be aware of the risks associated with drug abuse and seek help if necessary. By taking steps to prevent and treat substance use disorders, individuals can promote their overall health and well-being, as well as protect their vision.
