CBD for Eye Health: Protecting Vision Naturally

CBD for eye health

Vision is a crucial aspect of our daily lives, enabling us to interact with the world around us. Yet, the health of our eyes can often be taken for granted until issues arise. Many individuals face eye conditions that can significantly impair vision and overall quality of life. Emerging research into Cannabidiol (CBD), a non-psychoactive compound found in cannabis, suggests potential benefits for our eyes, offering hope for natural, supportive care.

Common Eye Conditions and CBD’s Potential Benefits

Glaucoma or Increased Intraocular Pressure

Glaucoma is an eye condition that leads to optic nerve damage, primarily due to elevated intraocular pressure (IOP). This condition is a significant health concern, ranking as one of the primary causes of blindness among individuals aged 60 and older. Lowering IOP and the protecting the optic nerve are crucial in preventing the progressive vision loss associated with glaucoma.

Recent studies, including this notable one [1], have delved into the potential of cannabinoids, such as cannabigerol (CBG), to offer supportive care in glaucoma management. These compounds have shown promise in lowering eye pressure and enhancing aqueous humor uveoscleral outflow, both key factors in the development and progression of glaucoma.

The research points to cannabinoids' ability to modulate eye pressure through several mechanisms:

  • Calcium Channel Inhibition: Cannabinoids may inhibit calcium influx in presynaptic channels within the eye, which contributes to reducing the production of aqueous humor, a primary factor in intraocular pressure.
  • Reduction of Noradrenaline Release: By diminishing noradrenaline release in the ciliary body, cannabinoids can further decrease aqueous humor production, leading to reduced eye pressure.
  • Neuroprotective Properties: Particularly noteworthy is CBG's neuroprotective effect on retinal cells. This attribute, coupled with its non-psychoactive nature, positions CBG as a compelling candidate for further research in glaucoma care.

While promising, the use of cannabinoids like CBG and CBD in managing glaucoma and supporting eye care should be approached as part of a multifaceted strategy. It's crucial to underscore that these natural compounds are not used to treat glaucoma but could serve as valuable tools in managing eye conditions alongside conventional therapies. Continued research is essential to fully understand the optimal use of cannabinoids to help with glaucoma or other eye conditions, emphasizing the importance of healthcare consultation before integrating new supplements into your regimen.



Age-related Macular Degeneration (AMD)

AMD affects the macula, the part of the eye responsible for clear vision in your direct line of sight. As a leading cause of vision loss, AMD's progression can be devastating. CBD’s anti-inflammatory and antioxidant properties could potentially protect against cellular damage and reduce inflammation, slowing the progression of AMD and supporting overall retinal health.

Research on the use of cannabinoids, such as CBD, for age-related macular degeneration (AMD) is still in its early stages, and there is not enough scientific evidence to support CBD as a standard treatment for AMD. However, some studies and reports suggest that cannabinoids, including CBD, could potentially help with AMD symptoms or prevent the progression of the disease.

Age-related Macular Degeneration


Cataracts cause clouding of the eye's lens, leading to a decrease in vision. While surgery is the most common and effective treatment, CBD’s antioxidant properties might help manage oxidative stress associated with cataract development, possibly providing supportive care to maintain lens clarity and prevent early onset.


Diabetic Retinopathy

This condition is a complication of diabetes that affects the eyes due to damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). 

The potential of CBD in protecting against diabetic retinopathy has been discussed in several studies. A review focused on the therapeutic effects of cannabidiol (CBD) as an emerging and novel therapeutic modality in ophthalmology based on systematic studies in animal models of inflammatory diabetic retinopathy [9]. The review emphasized the therapeutic effects of CBD on animal models of diabetic retinopathy, highlighting its potential to reduce retinal inflammation and vascular damage. 

Additionally, a study postulated a mechanism of action for cannabidiol as a potential therapy for diabetic retinopathy, suggesting that CBD works as an antioxidant and immunosuppressive agent to protect the eye from the vascular and neuroinflammatory effects of diabetic retinopathy [5]. 

Furthermore, a study from 2006 indicated that a compound found in marijuana, cannabidiol, may help protect the eye from the vascular and neuroinflammatory effects of diabetic retinopathy [11]. These findings collectively suggest that CBD's potential to reduce inflammation and vascular damage could play a role in protecting against diabetic retinopathy. However, further research and clinical studies are needed to fully establish the efficacy and safety of CBD as a treatment for diabetic retinopathy.

How Does CBD Affect the Eyes?

CBD's effects on the eyes are primarily attributed to its interaction with the body's endocannabinoid system (ECS), a complex network of receptors, enzymes, and endogenous cannabinoids that plays a crucial role in maintaining physiological homeostasis. The ECS is involved in regulating a variety of bodily functions, including immune response, inflammation, and pain perception, all of which can have implications for eye health. Here's how CBD influences our eyes through its mechanism of action:

Combatting Inflammation 

Inflammation is a critical factor in the onset and progression of numerous eye diseases. Persistent inflammation can damage delicate eye tissues, leading to conditions such as uveitis, dry eye syndrome, and contribute to the severity of diseases like macular degeneration and glaucoma. CBD’s potent anti-inflammatory properties could play a significant role in calming inflammation within the eye. By interacting with the body’s endocannabinoid system, CBD may help regulate immune responses and reduce the production of inflammatory cytokines, thereby offering a soothing effect on inflamed eye tissues and helping preserve vision.

Antioxidant Protection Against Oxidative Stress

The eye, particularly the retina, is highly susceptible to oxidative stress due to its high metabolic activity and exposure to light. Oxidative stress is a major contributing factor to age-related eye diseases, including age-related macular degeneration (AMD) and cataract formation. CBD's powerful antioxidant capabilities suggest it could counteract oxidative damage by scavenging free radicals, thus potentially slowing the progression of degenerative eye diseases and protecting the cells in the retina and other parts of the eye from oxidative stress-induced damage.

Enhancing Vascular Health in the Eyes

Proper blood flow and vascular health are essential for maintaining healthy eyes, supplying necessary nutrients, and removing metabolic waste. Conditions such as diabetic retinopathy, characterized by damage to the blood vessels in the retina, highlight the importance of vascular integrity for eye health. CBD’s potential vascular benefits, including its ability to reduce blood pressure and exert protective effects on blood vessels, could support better blood flow to the eyes. This may not only help reduce the risk of vascular-related eye issues but also aid in the management of existing vascular issues in the eyes, promoting healthier retinal function.
