How marijuana act as a treatment for our eyes?

Many of the marijuana users have the recognized red eye experience. While a few may find the cannabis noticeable effects on the eyes to be troublesome, there are numerous astounding ways that cannabis supports visual health. From lessening symptoms of eye infections to staving off degenerative sightlessness, here’s what you need to know about how marijuana act as a treatment for our eyes. So how marijuana act as a treatment for our eyes:

Marijuana may aid you to see things a in a different way. Research suggests that the marijuana plant can have an impact on every organ in the human body, as well as the eyes.

While it may sound too good to be true, marijuana herbs work the unexplained magic in the eyes by tapping into one of the largest cellular communication networks in vertebrates. This network is the endocannabinoid system (ECS). Cannabis herbs work together with the ECS by engaging a special type of cell receptor, called a cannabinoid receptor. The human eye happens to express high levels of one particular cannabinoid receptor, the CB1. Vision processing centers of the brain also feature a bounty of these landing sites. In addition, preclinical investigations suggest that the ECS plays a crucial role in our vision.

A 2016 primate study published in Neural Plasticity has found that manipulating cannabinoid receptors changes the way electroretinographic waves pass through the retina.

These waves are measured by an electroretinogram, which records the electrical response of the eye to a light stimulus. The researchers found that cannabinoid receptors moderated the eye’s response to light.

The ways in which cannabis affects eyesight needs further investigation. However, this early research offers even more reason to investigate cannabis as a treatment for diseases of the eye.

Red Eye

Wider capillaries mean blood flows into the eyes, reducing intraocular pressure. This could be beneficial for patients with painful ocular conditions like glaucoma.  Cannabis lowers blood pressure. This causes capillaries and blood vessels to dilate, leading to what is commonly referred to as red eye.Red eyes may be a tell-tale giveaway that you’ve consumed a little marijuana, those who experience tension around the eye might appreciate the relaxing effects of the marijuana plant.


Signs of allergy typically include itchiness, redness, inflammation, tearing, and dryness. This can be triggered by an allergy to smoke, residual molds, or the cannabis plant itself.

In 2015, research from the American College of Allergy, Asthma, and Immunology suggests that cannabis allergy is similar to Hay Fever, causing eye irritation and an itchy nose for those exposed to smoke, pollen, or plant material.

Enhanced night vision

For the past three decades, researchers have speculated that cannabis may also improve night vision. In the 1990s, M.E. West, a pharmacologist, noticed that Jamaican fishermen who consumed a cannabis elixir had an “uncanny ability to see in the dark.”

A small study conducted in 2004 tested the effects of traditional cannabis Kif and a synthetic THC in three Moroccan individuals. Kif is a mixture of cannabis and tobacco. This small experiment found a dose-dependent relationship between cannabis consumption and improved night vision.

Visual processing

The endocannabinoid system contributes to visual development in the brain. A study from University of Waterloo, University of Auckland and Brown University found that babies exposed to cannabis in utero scored significantly higher in visual processing tests.

While babies exposed to alcohol scored lower in visual processing tests, those exposed to cannabis had improved global motion perception. This is certainly not a reason to consume cannabis during pregnancy, but these findings do add fuel to the idea that cannabinoids and the ECS help the eyes and brain make sense of visual information.
