Hemp cbd oil benefits for eyes
But cannabis can also affect the eyes in other ways. Now, some research suggests that the neuroprotective and antioxidant properties of marijuana compounds cannabidiol CBD and tetrahydrocannabinol THC may be able to support vision and offer some protection against common diseases of the eye and optic nerve. Relatively little research has been done on how—or whether—cannabis can affect vision , prevent any of the common eye diseases or relieve symptoms of those diseases. While some studies propose that cannabis has clear benefits for eye health, others claim the opposite, that cannabis can actually harm vision and the pathways for processing visual information in the brain. Complicating that picture are the many accounts by cannabis consumers themselves, who say that cannabis makes vision sharper and reduces the symptoms of glaucoma, a common eye disease. All these things can affect the various parts of the visual system, including the tissues of the eye itself, the optic nerve, and the neural pathways in the brain that process and store visual information.
The Medical Impact Cannabis Can Have On Our Eyes And Vision
Cannabidiol, or CBD, is a chemical found in the cannabis plant. Under the Agriculture Act, hemp and CBD were made legal in all 50 states, although some in the medical field say there still is confusion over the specifics. Nonetheless, this has helped to set off a brigade of products and companies touting the health benefits of CBD.
Outside of the world of eyes, some researchers and patients have found some specific benefits for CBD. Morrison said. It is the workhorse of the cannabinoids. In clinical trials, CBD has been shown to be an effective treatment for epilepsy, according to a report from the World Health Organization. Other CBD-based drugs are under development, including Arvisol Echo Pharmaceuticals , which is in pre-clinical testing for epilepsy and schizophrenia. On the consumer level, CBD users are reporting that they have found relief from sleep problems, inflammation, and stress and anxiety, according to Brenda Green, MEd.
There are also many who purchase CBD oil for pet anxiety or inflammation, she added. Some parents are trying CBD for attention deficit disorder in their children. The use of CBD is most effective as a tincture placed under the tongue or vaped, although some consumers dislike the idea of using a vape, Ms. Green said. Jordan Tishler, MD, cautions that research on CBD dosing has shown that you cannot vape enough to get an effective treatment. Cannabidiol has few side effects. Some studies have noted fatigue, diarrhea, and change in appetite, but these are considered rare, Ms.
Ophthalmologists may wonder how all this comes back to eye health. Because marijuana has had a long-time association with glaucoma even if scientific evidence does not back it , medical professionals and patients tend to ponder whether CBD also can improve eye health, be it for glaucoma or other ocular issues. A Canadian study of CB1 and CB2 receptors in monkeys concluded that manipulating the endocannabinoid system may help restore normal vision and protect the retina.
The effect of THC was sex-dependent, with longer effects in male mice. Straiker said. Between research and practice, for now, there is no CBD treatment recommended specifically for the eyes.
Tishler said. Clifton sees potential for CBD and certain eye health issues. Clifton said. She perceived several of the previous studies conducted as biased against cannabis. Research on CBD in the U. One of many questions that could be explored with further research is what happens in subjects who smoke high-CBD varieties of cannabis, Dr.
Ophthalmologists can use their growing knowledge of CBD to guide patient queries appropriately, particularly in states where marijuana has been legal for a longer length of time. Ophthalmologist Ray Chan, MD, receives one or two questions a month about CBD or marijuana, mostly from patients who have a stronger interest in alternative medicine.
Product quality is also key. There are a lot of CBD products entering the market, but that does not necessarily mean they are all effective, Ms. Clifton also recommends tinctures or vaping and steers patients away from edibles, which can take longer to be effective.

For someone to achieve a sustained IOP lowering, they need to constantly use the drug, which could lead to systemic changes to the brain, lungs, and cardiovascular system, he explained.
In a paper, the American Academy of Ophthalmology said there is no evidence that marijuana provides an increased benefit for or diminished risk of glaucoma compared to the traditional treatments available.

Pressure In Eye With CBD. ▷ While we often hear of marijuana being able to lower the pressure in the eye; this is only with THC, the psychoactive cannabinoid. Researchers also found that THC and CBD affected eye pressure can build up a tolerance to marijuana's eye pressure lowering effects.
Recently though, CBD, or cannabidiol, has gained international attention for being a panacea for many different physical complaints. However, CBD contains none of the psychoactive ingredients of cannabis, and therefore will not cause any mind-altering effects. CBD can be used to address a wide range of issues, including disorders of the eye. Its anti-inflammatory effects alone are worth looking into for anyone with eye pain, strain, blurred vision, floaters, and migraine auras.
Update: January 24,
Iolanda Bulgaru. Thanks to its antipsychotic tendencies, it is also used widely for recreational purposes. Controversial as it might be, the CBD popularity wave has gained increased traction across the country and beyond.
How Does Cannabis Affect Your Eyes?
A new study suggests that CBD doesn't lower eye pressure, it raises it. Glaucoma is a condition that damages the optic nerve at the back of the eye. It's the nerve that transmits visual information to the brain, allowing us to see. Glaucoma is often linked to a buildup of pressure inside the eye. The increased pressure can damage the nerve, leading to permanent vision loss.
CBD Oil May Worsen Glaucoma
Pain perception is a critical self-defense mechanism for the body. Pain tells us to steer clear of adverse stimuli—think of a hand over a flame. Ocular pain, a source of acute discomfort, may be a signal that prevents damage to the eye from exposure to a noxious chemical or a mechanical probe, for example. However, in aberrant conditions pain signaling—nociception—can become dysfunctional. Prolonged impulses of pain will cause the nervous system to lock into a hyper-sensitized mode. This is referred to as neuropathic pain, a chronic debilitating condition that affects eight percent of the entire population in Western Countries. The cornea, the transparent lid over the iris, has one of the highest concentrations of sensory nerve endings in the body, which makes it extremely sensitive to touch, temperature and chemicals. Contact with the cornea triggers an involuntary reflex that closes the eyelid.
Cannabidiol, or CBD, is a chemical found in the cannabis plant. Under the Agriculture Act, hemp and CBD were made legal in all 50 states, although some in the medical field say there still is confusion over the specifics.
At an early age, most of us are taught that we have five senses, and vision is one of those. Overall, though, each of our senses are our main contact to the environment we live in. Although our vision helps us in more ways than we might realize, there are several eye issues that can occur at any time like glaucoma, neurodegenerative blindness, and diabetic retinopathy.
CBD for Glaucoma
One of the most commonly proposed uses of medical marijuana is to treat glaucoma. But a study from researchers at Indiana University has found that a major chemical component in the substance appears to worsen the primary underpinning of the disease: a rise in pressure inside the eye. The chemical that causes this rise in pressure is cannabidiol, or CBD, a non-psychoactive ingredient in cannabis that is increasingly marketed to consumers in products such as oil, gummies, creams and health food. It is also approved in many states as a treatment for conditions such as pediatric epilepsy. The study was reported Dec. The study, which was conducted in mice, specifically found that CBD caused an increase in pressure inside the eye of 18 percent for at least four hours after use. Tetrahydrocannabinol, or THC, the primary psychoactive ingredient of marijuana, was found to effectively lower pressure in the eye, as has been previously reported. Specifically, the study found that male mice experienced a drop in eye pressure of nearly 30 percent eight hours after exposure to THC alone. A lower pressure drop of 22 percent was also observed after four hours in male mice. The effect was weaker in female mice. This group experienced a pressure drop of only 17 percent after four hours.
CBD in marijuana may worsen glaucoma, raise eye pressure
