Cannabidiol (CBD) – What We Know and What We Don’t. (August 2018). Harvard Health Publishing, Harvard Medical School.
One of the first studies on medical marijuana for eye conditions involved glaucoma. This is a group of serious eye disorders associated with damage to the optic nerve, usually due to high fluid pressure in the eye, or intraocular pressure (IOP). This pressure must be lowered to prevent blindness. Further studies of medical marijuana have found that the drug does not actually lower pressure for long enough. (Learn more)

Most medical research suggests that CBD does not intoxicate you the same way THC does, but taking types of medical marijuana marketed as “high CBD” might mean there are traces of THC included in the substance. THC is addictive because it can change brain chemistry to make you feel relaxed, less anxious, sleepy, or even happy. The drug can also cause negative side effects like changes in mood, spikes in anxiety or paranoia, delusions, and trouble thinking or problem-solving.
However, the studies also found that these pressure-lowering effects would wear off after a certain amount of time, while the effects of glaucoma eye drop treatment lasted at least 12 hours. It is vital for eye health that treatment to manage intraocular pressure lasts for a long time and is consistent. When eye pressure rises and lowers several times throughout the day, damage to the optic nerve can get worse.
Medical marijuana has been touted to generally ease physical and emotional pain, including nausea related to cancer treatment, chronic pain, general anxiety disorder, and other conditions. In the 1970s and 1980s, medical marijuana was studied as an eye treatment, particularly for serious conditions like cataracts and glaucoma, which can lead to blindness. The research found that marijuana could lower intraocular pressure for three or four hours at a time, and it was more effective at lowering pressure in the eyes than glaucoma drops.
As marijuana has become more popular and many states have legalized both medical and recreational uses for this drug, CBD oil is being promoted for a range of uses, including as a glaucoma treatment.
At the moment, the only one that’s easily accessible is the C Better Daily from the ProTeam Brady Team (named for one of the founders, not for Tom Brady). The online CBD Hemp Super Store sells CBD eye drops made with chamomile hydrosol, Eye bright, NAC, and CBD.
Keeping your eye on CBD industry updates is a good idea if you want to keep ahead of the wellness curve. However, putting CBD in your eyes, at this point, is something you should try to avoid—no matter which company claims to have the best CBD eye drops.
Eye drops aren’t just for beating hay fever or reducing a bout of red eye. For people with glaucoma, eye drops can be an essential way to relieve the resultant pressure and save your vision.
Are Even the Best CBD Eye Drops Dangerous?
While the World Health Organization maintains that CBD has no identifiable risk of dependence or abuse, there is still no certain answer whether or not CBD eye drops are dangerous.
Until then, it’s too early to recommend any CBD eye drops. The research is, at worst, a strong case against CBD eye drops, and, according to Alex Straiker, PhD., contradictory at best. We’ll be sure to update you with our choices for the best CBD eye drops once these products are refined and safe to use.
Though some studies have already proven that using CBD eye drops is not the best idea for eye health, the research has just begun. The neuro-protective, anti-inflammation, antioxidant properties of CBD are well known, and there’s hope that science can figure out a way to apply it to eye health.
Studies into how marijuana affects the eyes are still underway. Slowly but surely, we’re collectively learning what effects, both short and long term, it can have on eyesight.

CBD can address the inflammation and we believe, can help prevent the endpoint of all ocular diseases which is blindness.

Inflammation leads to damage to the cornea, uvea, retina, and ultimately to the optic nerve.

Diabetes causes superoxide formation which leads to the release of adenosine and pro-inflammatory cytokines. In preclinical studies, CBD was found to block superoxide formation. CBD produced the antioxidants that reduced the inflammation in the damaged retina of the diabetic.
