1. CBD Reduces Eye Redness
CBD eyedrops offer an excellent way to treat red, bloodshot eyes. This symptom occurs as the result of blood vessels that become excessively dilated. Ironically, red eyes are a common side effect of recreational cannabis use. Yet they may also stem from a variety of other causes.
While usually nothing more than a nuisance at its worst, bloodshot eyes may be painful and make it difficult to see clearly. CBD relieves these problems thanks to its inherent ability to increase blood pressure. When used topically in the eyes, eyedrops containing CBD can help constrict the blood vessels that cause redness.
2. CBD Reduces Corneal Pain and Inflammation
CBD also offers relief from more serious eye problems. In particular, CBD alleviates many of the key symptoms associated with damage to the nerve endings of the cornea. Such damage may stem from trauma, surgery, infection, or neurological disease. The inflammation and pain associated with such damage can often be quite debilitating.
A study published in February 2018 found that CBD showed a significant ability to reduce both pain and inflammation in damaged corneas when applied topically. Specifically, the CBD accomplishes these tasks by binding with key receptors in the eye.
3. CBD May Prevent Macular Degeneration
Macular degeneration refers to the deterioration of the central part of the eye’s retina, also known as the macula. The macula is closely involved in translating the information received by the eye and sending it to the brain to be interpreted. As the macula naturally breaks down over time, the brain begins struggling to receive information properly.
Scientists remain somewhat in the dark regarding the specific factors involved in macular degeneration, although heredity, environment, and age all play significant roles. Likewise, the beneficial effects of CBD — and cannabis in general — have yet to be thoroughly studied. Yet early results indicate that the anti-inflammatory, antioxidant, and neuroprotective qualities of CBD may prove highly beneficial when it comes to preventing cell death in the eyes.
