Potential Eye-Related Effects of CBD Oil Use
In the realm of health and wellness, CBD (cannabidiol) is making waves for its potential therapeutic benefits. This chemical compound, extracted from the cannabis plant, is under investigation for its possible role in treating various conditions, including those affecting the eyes.
One such condition is glaucoma, a group of eye diseases that can damage the optic nerve and result in vision loss. Some research suggests that CBD may increase the pressure in the eyes, a factor that could potentially make it unsuitable for those with glaucoma. However, it's important to note that other cannabinoids like THC or cannabigerol (CBG) have shown more established potential to lower intraocular pressure (IOP) and provide retinal protection [1][3].
Conversely, a recent study indicates that CBD may possess antioxidant properties, which could help reduce oxidative stress and preserve retinal ganglion cells, potentially beneficial for glaucoma and possibly diabetic retinopathy. Yet, more evidence is needed to confirm this [4].
When it comes to diabetic retinopathy, direct research on CBD's effects is sparse. However, given its antioxidant and anti-inflammatory properties, CBD might have theoretical potential to mitigate retinal damage caused by diabetic microvascular complications. This remains unproven and requires further clinical study.
The endocannabinoid system (ECS), a biological system that helps regulate and balance key bodily functions, plays a role in pain and inflammation, and the eyes feature many cannabinoid receptors. This suggests a potential for CBD to offer benefits for treating certain eye conditions due to its anti-inflammatory, antioxidant, and neuroprotective properties.
The 2018 Farm Bill made some hemp-derived CBD products with less than 0.3% THC federally legal, but CBD products containing more than 0.3% THC are still federally illegal.
In summary, while cannabinoids are being explored for ocular neuroprotection and pressure modulation, CBD alone currently has contradictory evidence regarding glaucoma—some studies indicate it may increase IOP, posing risks—so it is not generally recommended for glaucoma treatment at this time. Evidence supports that other cannabinoids like THC and CBG may be more promising for glaucoma. The role of CBD in diabetic retinopathy is still underexplored but may relate to its antioxidant effects [1][2][3][4][5].
As always, more research is necessary to fully understand the potential benefits and risks of CBD for the eyes. It's crucial to consult with healthcare professionals before starting any new treatment regimen.

- CBD, extracted from the cannabis plant, is being studied for its potential role in treating various medical conditions, including eye-related diseases like glaucoma and diabetic retinopathy.
- Some research indicates that CBD might increase the pressure in the eyes, which could potentially make it unsuitable for individuals with glaucoma, although other cannabinoids like THC and CBG have shown more promise in lowering intraocular pressure.
- A recent study suggests that CBD may possess antioxidant properties that could help reduce oxidative stress and preserve retinal ganglion cells, potentially beneficial for glaucoma and possibly diabetic retinopathy, although more evidence is required to confirm this.
- The role of CBD in diabetic retinopathy remains largely unexplored, but given its antioxidant and anti-inflammatory properties, it might theoretically help mitigate retinal damage caused by diabetic microvascular complications.
- The endocannabinoid system, which helps regulate key bodily functions and features many cannabinoid receptors in the eyes, suggests a potential for CBD to offer benefits for treating certain eye conditions due to its anti-inflammatory, antioxidant, and neuroprotective properties.
- While CBD alone has contradictory evidence regarding glaucoma and is not generally recommended for glaucoma treatment at this time, more research is necessary to fully understand its potential benefits and risks for the eyes, particularly when it comes to fitness-and-exercise, mental-health, skin-care, nutrition, and various therapies-and-treatments. Consulting healthcare professionals before starting any new treatment regimen is essential.
