Eye Drops for Stoners FAQ
Why Does Smoking Weed Cause Red Eyes?
Smoking weed can lead to red eyes because it causes blood vessels in the eye to dilate. Essentially, weed smoking causes an increase in blood pressure and increased blood flow, making veins expand. This makes them look more visible in your eyes.
When Do You Put In Eye Drops: Before or After You Smoke Weed?
You can put in eye drops about 20 minutes before you smoke weed. Eye drops have active ingredients that can give you clear eyes in no time.
Is Long-Term Eye Drop Use Bad?
Generally, using eye drops every day to relieve red eyes is not recommended. At most, you should use them a few weeks at a time or less. Certain eye drops have active ingredients that can actually make your red eye problem worse and increase your tolerance for them, making them less effective over time.
How Often Should You Apply Eye Drops Per Day?
Eye drops should be applied about once or twice per day, at most. While you can use them several times per day, it is not recommended for long-term use. Always follow the manufacturer's instructions on how to apply them.
How do you get rid of bloodshot eyes quickly?
-Apply cold compresses on closed eyelids
-Gently rub your eyelids together
-Wash your eyelids gently
Does having red eyes mean a lack of oxygen?
Lack of oxygen in the eyes causes the blood vessels to dilate and appear red, which is why you frequently have red eyes when you're sleep deprived.
Does dehydration cause red eyes?
Different effects of dehydration are seen in the tissue surrounding the eye. It may result in sunken eyes and dark circles under the eyes. In addition to blurry and double vision, dehydration can also produce dry, red, and irritated eyes. Dehydration may also indicate systemic conditions that harm the eyes.
What does bloodshot eyes mean from cannabis?
When you use cannabis, the cannabinoid THC makes you feel “high.” Additionally, it damages your blood vessels, which results in red eyes. THC use causes blood vessel dilatation by lowering blood pressure. Your body's blood flow is increased by this dilation, including to your eyes.
Why does cannabis make my eyes red?
Tetrahydrocannabinol, or THC, is the main ingredient that causes red eyes from cannabis use. THC reduces blood pressure by widening blood vessels and capillaries. The eyes seem red as a result of this increased dilatation, particularly in the ocular capillaries, which increases blood flow.
Does everyone get red eyes after using cannabis?
Red eyes don't affect everyone in the same way. Individual physiologies, the quantity of THC ingested, and the mode of ingestion can all affect the response.
Are red eyes from cannabis harmful?
The typical side effect of cannabis use is red eyes, which are just the body's reaction to THC. Usually, they don't show any signs of eye damage.
How long do red eyes last after using cannabis?
Red eyes often remain as long as the primary effects of cannabis, which are frequently a few hours. However, this can vary. Factors like personal tolerance levels and the quantity of THC ingested might affect how long it lasts.
Can I prevent red eyes when using cannabis?
It can be difficult to completely avoid red eyes, but you can lessen the intensity by utilizing strains with lower THC levels or eating lesser amounts. Eye drops and watering the eyes might also be helpful.
Are there any eye drops that can help with cannabis-induced red eyes?
Yes, some of the best ones are available in the top of this article.
Is the red-eye effect stronger with certain cannabis strains?
Yes, strains with higher THC content typically have more noticeable affects on the eyes. Lower THC or higher CBD strains could not have as much of an impact.
Can edibles cause red eyes?
Yes, eating cannabis in an edible form can still result in red eyes because THC is the main ingredient, regardless of how it is consumed.
Do red eyes indicate the quality of cannabis?
THC concentration can be determined more by looking at red eyes than by overall quality. Red eyes alone aren't a good indicator of quality because different high-grade strains have different THC concentrations.
Are there long-term effects on the eyes from regular cannabis use?
There is no proof that cannabis's red-eye impact will have any lasting effects on eye health. However, you should speak with a medical expert if you already have any ocular issues.
It’s nearly impossible to hide that you’ve smoked cannabis unless you have some good eye drops. Red eyes, also known as marijuana eyes are a dead giveaway for having smoked marijuana recently.
But did you know that marijuana can have health benefits for your eyes, too?!
Consuming cannabis can provide significant visual health benefits beyond your bloodshot eyes. In the body, cannabis interacts with an extensive network of cell receptors and chemical signals known as the endocannabinoid system (ECS).
Cannabis compounds (cannabinoids) act similarly to naturally produced endocannabinoids and may be used to treat endocannabinoid deficiencies. High concentrations of the CB1 cannabinoid receptor can be found in the human eye and brain areas involved with visual function.
Researchers found that cannabinoid receptors regulated how the eyes responded to light.
More research needs to be done into how cannabis use affects our visual function, for better or worse. We all know that consuming cannabis can produce mild adverse effects like red eyes and dry mouth, but we are starting to uncover the many benefits it can have on our eye health.
Red Eyes Also Known as Marijuana Eyes
Why does consuming cannabis cause red eyes? Cannabinoids can cause the dilation (widening) of blood vessels, thereby increasing blood flow to certain areas and causing a decrease in blood pressure. Increased blood flow to the eyes can make them look red.
While cannabis is known for its anti-inflammatory effects, it has also been known to cause allergic reactions in some cases.
Smoking cannabis if you have a weed allergy or an allergy to smoke or molds in the bud can cause red and watery eyes, runny nose, sneezing, nausea, and hay fever.
A 2015 article from the American College of Allergy, Asthma, and Immunology described several case reports of negative reactions to cannabis.
Symptoms include allergic reactions, hypersensitivity, and anaphylaxis. Researchers noted that marijuana pollen or smoke exposure can cause symptoms of hay fever and asthma.
Research has shown that cannabis use is associated with enhanced night vision. Jamaican fishermen have long described how smoking marijuana or taking a rum-based marijuana tincture improves their night vision and research backs this up.
A 2004 study on a small group of Moroccan subjects found that smoking Kif or synthetic THC produced dose-dependent improvements in night vision. A 2016 study on retinal cells in tadpoles found that the application of synthetic cannabinoids to the eyes made the cells more sensitive to light.
2015 research found that children exposed to cannabis in the womb displayed a “significant improvement in their ability to track moving objects at age four.” Researchers, however, warn parents that this does not mean cannabis has health benefits on fetal development.
The study from the University of Waterloo, University of Auckland, and Brown University found that exposure to cannabis enhanced global motion perception. In contrast, alcohol exposure was linked with lower visual processing test scores.
The same dilation of the blood vessels that causes red eyes after consuming cannabis has helped glaucoma patients find relief. Glaucoma is a condition that affects the eye’s optic nerve. Over time, the disease can worsen and lead to blindness if not treated.
Research into how cannabis affects glaucoma has been ongoing since the 1970s. In a 1979 experiment on 16 test subjects, inhalation of marijuana reduced intraocular pressure associated with pain and damage caused by this condition. Patients felt pain relief for up to four hours.
A study on 18 subjects in 1980 found that marijuana inhalation was followed by elevated heart rate and decreased intraocular and blood pressure. In 2000, researchers found that a non-psychotropic cannabinoid reduced intraocular pressure for 6 hours in normotensive rabbits.
2014 research published in Experimental Eye Research suggests that the cannabinoid agonist HU210 may be able to delay retinal degeneration in rats with retinitis pigmentosa (RP), a rare genetic disorder that results in a loss of retina cells.
In the study, rats were given a synthetic cannabinoid over 90 days. After the testing period, researchers tested the degeneration of cells. Rats that received cannabinoid treatment had 40% more photoreceptors than non-treated rodents.
Diabetes can cause a wide range of complications, including diabetic retinopathy, a condition that damages the blood vessels in the retina. As nerve cells degenerate, a person’s eyesight can worsen. A 2006 preclinical study found that cannabidiol (CBD), a non-intoxicating cannabinoid, can offset toxicity in the retina that reduces retinal damage.
However, a 2017 study found a link between regular cannabis use and ganglion cell dysfunction, which causes damage to the retina. Keep in mind that these findings are preliminary, so more research needs to be done to provide guidance for safe cannabis use.
