Can CBD affect vision?

Known for its anti-inflammatory properties and pain-relieving uses, CBD is now a popular option for those struggling with chronic pain or health conditions, and its popularity is only increasing with more in-depth and more insightful research. With many studies showing CBD having positive effects on anything from long-term health conditions to degenerative diseases, it’s no surprise that vision is one of the areas of focus for these studies.

Several degenerative conditions can affect vision, including glaucoma, and some research has even shown that cannabis can have a direct effect on cataracts and similar conditions experienced by older users. As such, for those with these kinds of health conditions, CBD could be beneficial to their vision by reducing the effects of ongoing or chronic medical problems.

For people without those concerns, does CBD have an impact on vision in general? 

Because CBD works directly with the body’s endocannabinoid system (ECS), it has been suggested that CBD may actually have a positive effect on vision. The ECS is found throughout the body and has a large concentration of CB1 receptors within the tissues of the eye itself. As such, the consumption of cannabis can lead to responses directly from the visual system.

According to research carried out in 2017, the actual effects of cannabis on the quality of eyesight is variable. This could be due to many different factors, including the type of cannabis used by the person, as well as the circumstances and the way in which it is used. Even the number of CB1 receptors within an individual’s eye may have an impact on whether or not CBD could affect visual sensitivity.

For some CBD users, it seems that regular use of this medication could lead to improved night vision – though there is currently little conclusive research suggesting if this is consistently true, or just for a handful of people. Based on the research now available, it seems like CBD can have a positive effect on vision. While the effects of smoking cannabis may lead to the customary appearance of red eyes, there is still little evidence that this actually leads to a reduction in vision, mainly when used in small amounts.

For those taking CBD in any form for other conditions, it’s unlikely that they will see a change in vision. However, as more research develops into the effects of CBD on ocular diseases, CBD eye drops may become a viable medical option in the future.
