There’s a lot of talk about what cannabis can and cannot do. The herb surely comes with many health benefits – from alleviating chronic pain to reducing the severity and frequency of seizures. Now that weed has finally been added to the legal list in most states, it has become more accessible.
This brings us to what the substance can do for the eyes. There are mixed opinions in this regard – some say cannabis can improve eye health while others disagree. Several research works show that CBD can be a treatment worth exploring for glaucoma. However, the American Academy of Ophthalmology doesn’t favor the use of cannabis for glaucoma.
Cannabis And Your Eyes
Ever noticed the red, almost bloodshot eyes of pot smokers? Thank cannabis for this effect. Cannabis lowers ocular pressure which causes capillaries to widen and pupils to dilate. While such reddened eyes look horrifying, the visual organs are actually relaxed. Other than this, cannabis also improves night vision. This gives some hope that the herb may help with eyesight as well.
This benefit of improved night vision is not due to CBD though. In fact, tetrahydrocannabinol, the psychoactive component of cannabis, takes the credit for that. One study found that the THC in cannabis interacts with the cannabinoid receptors in the eyes. By doing so, it can improve the ability to see at night.
Another indication that cannabis may improve vision is that it can reduce age-related blindness. Science shows that cannabis contains antioxidants that can reduce the risk of or slow down neurodegenerative blindness. Back in 2004, a group of fishmen claimed that they were able to see better when they consumed cannabis. Testing showed that they weren’t wrong.
So, Can Cannabis Be Used For Improving Vision?
Can you add cannabis to the list of foods that can improve your eyesight likes nuts, legumes, and carrots? Not much can be said about this. Research is scarce on the subject. In fact, if you look at the overall studies conducted on cannabis you’ll find that evidence on its effect in other areas of health is also limited.
One JAMA research concluded that cannabis can harm your sight overtime. Furthermore, some folks might also find that they are allergic to the herb. Since the long-term effects of what cannabis does to your eyes on the whole or your eyesight in particular are not known, it’s best to not use the herb. Some say that marijuana can only improve vision when you take it in high amounts. And intake of huge quantities of weed is not good for health.
There’s some research that shows that cannabis can be useful in some ways in the eye health department. It may help with glaucoma, but experts still don’t agree on its use here. Weed can relax your eyes and also may improve night vision. However, since research is limited it is best to not use cannabis for vision or eye health.
