You can get red and bloodshot eyes from eye conditions such as digital eye strain, wearing contacts, dry eyes, and not getting sufficient sleep. Digital eye strain is also called computer vision syndrome. On average, an individual spends around seven hours in front of their computer or tablet every day, which can result in headaches, blurriness, and eye strain. Make sure you look at your computer from a distance and have the proper posture to minimize the chances of straining your eyes.
THC has the same effect on the body and mind as anandamide – often called the ‘bliss molecule.’ Anandamide is a fatty acid neurotransmitter that attaches to the same receptor that THC does. It has the effect of making you feel happier, calmer, and even excitable at times. Anandamide dilates blood vessels, which lowers blood pressure. THC has a similar effect – marijuana allows more blood to shoot into the eyes since it has a higher content of THC .
Your eyes may get red when the tiny blood vessels situated between the sclera and overlying conjunctiva of the eye get dilated. There are various lifestyle and environmental-related factors that may cause these small blood vessels to get swollen or expand. The most prevalent causes of red eyes are eye infections, eye fatigue, and allergies. Wearing contacts throughout the day is another factor that usually leads to red eyes. They let your eyes can get dry and strained if left on for long. Red eyes can also result from more severe eye diseases and conditions such as glaucoma.
You probably know that one of marijuana’s prominent effects is causing red eyes, however, CBD does not share that feature. CBD is a natural compound found in marijuana and hemp plants. This cannabinoid interacts with the endocannabinoid system (ECS) of the body. The ECS plays an integral role in your body’s homeostasis. That means it plays a part in keeping an overall internal balance for many bodily functions. These includes memory, mood, digestion, appetite, stress, muscle formation, sleep, and so on.
If you use contacts, make sure that you clean and store them properly and never try reusing disposable lenses. If you’re going to touch the area surrounding your eye, make sure to wash your hands. This will help in preventing the chances of infection. Excessive consumption of alcohol, marijuana, and tobacco can also result in red eyes.
CBD, or cannabidiol as it’s known formally, is a compound found in hemp plants that researchers have been working to unlock the secrets of. For example, a recent clinical study found promise in using CBD when it comes to anxiety relief and sleep disorders. And favorable evidence has emerged about the efficacy of CBD as an adjunctive therapy in epileptic patients.
In the ECS, cannabinoids will bind to special receptors to produce different effects. It all sounds quite technical, but the important thing to keep in mind is that right now we know about two receptors in this system. They’re unflatteringly called CB1 and CB2 receptors. CBD has been shown to primarily bind to CB2 receptors while other cannabinoids, such as THC, behave differently and can bind to one or both receptors, depending on their own properties.
Why do people think CBD causes red eyes?
In this article, we’re going to tackle the issue of CBD and red eyes. We’ll explain where this myth comes from, why it’s untrue and chat briefly about what might actually be causing your red eyes.
CBD, on the other hand, has had a more recent rise to fame and has no psychoactive effects. In fact, some researchers have found that CBD can counteract the negative effects of THC.
But despite these great developments, there’s still a lot of stigma around something as simple as using CBD tinctures on a daily basis to improve quality of life and promote homeostasis. That’s because of the source and what else people associate with hemp.
There, Dr. Valenti highlights that although it is common to use marijuana to reduce pressure in the eyes, this is only because it contains much THC. She actually argues that CBD works to spike the eye pressure.What’s more, a 2008 human study that analyzed the different effects of CBD and THC doses on six glaucoma patients supports her claims.
In general, there are tons of different factors that may give you red eyes after using CBD. The CBD flower requires to have less than 0.3% THC to be lawfully commercialized. However, this tiny THC amount causes enough vasodilation to give slightly red eyes to some users!
What’s more, it is entirely possible to be allergic to certain flavonoids, terpenes, or other compounds in the hemp flower. Moreover, some people are somewhat sensitive to eye irritation, be it from dirt or from products like CBD.
The Science Behind Marijuana and Red Eyes
In an intriguing presentation, Dr. Denise A. Valenti shows us all we need to know about THC, CBD, and their corresponding intraocular pressure effects. In there, she clearly illustrates the opposing effects that CBD and THC seem to have on intraocular pressure.
Therefore, rest assured that CBD flowers do not generally make your eyes red. Remember, CBD has only slight vasodilator properties, so your eyes are unlikely to become flooded with blood. Meanwhile, THC is an excellent ocular vasodilator still recommended to address glaucoma to this day.
According to the study results, although a 5 mg THC dose reduced intraocular pressure, a 20 mg CBD dose showed a less noticeable effect. Then, a 40 mg CBD dose actually raised it.The specific physiology for these particular reverse intraocular pressure effects isn’t well-understood. However, it’s evident that THC and CBD have noticeable differences when it comes to reducing the pressure in the eyes and causing red eyes.
On the other hand, smoking CBD neither makes you high nor encourages dependency. Even more appealing is that there are close to none side effects to smoking CBD. Although smoking any substance may be harmful to your lungs and oral health.
