Cannabis and CBD for Cataracts
As you grow older, cataracts are very normal. According to the National Eye Institute, about half of all 80-year-old Americans either have cataracts or underwent surgery to rid themselves of cataracts. Perhaps you may not be able to notice the development of a cataract. Over time, however, cataracts may occur a blur, dull, or less color in your vision.
What are Cataracts
A cataract blocks the eye’s lens, which is usually clear. Seeing through cloudy lenses is a little like looking through a frosty or foggy window for people with cataracts. A blurry view of cataracts may make the reading harder, drive a car (in particular at night), or make it more difficult for a friend to see the expression on his face. Some cataracts develop slowly and do not affect your eye instantly. Nevertheless, cataracts can gradually interfere with your sight over time.
The lens inside the eye functions much like a camera lens with a clear focus on the retina. It also changes the focus of the brain, making us clearly see things both up and down. The lens mainly consists of water and protein. The protein is carefully structured so that the lens remains clear and allows light to pass.
But, as we age, a few of the proteins will clump together and cloud a small area of the lens. It is a cataract and may get bigger with a cloud of the lens over time, making it more difficult to see.
Nobody understands why the lens of the eye shifts when we age and cataracts. But global scientists have identified factors that may cause or are related to the development of cataracts.
Factors that increase your cataract risk include:
- Increased in age
- Excessive exposure to sunlight
- High blood pressure
- Previous eye injury or inflammation
- Previous eye surgery
- Prolonged use of corticosteroid medications
- Drinking excessive amounts of alcohol
Cataracts rarely occur or develop quickly at birth. They may develop or be transmitted during pregnancy by an infection for instance rubella of the mother. A cataract may also grow for another eye condition, including glaucoma, after an eye injury or surgery.
Symptoms of Cataracts
Signs and symptoms of cataracts include:
- Lamps, sunlight, or headlights seem too bright
- Clouded, blurred or dim vision
- Seeing halos around lights
- Sensitivity to light and glare
- Fading or yellowing of colors
- Frequent changes in eyeglass or contact lens prescription
- Increasing difficulty with vision at night
- Need for brighter light for reading and other activities
How Cannabis Can Help Relieve the Symptoms of Cataracts
According to Healing the Eye, another great use of medical marijuana is for the treatment of Glaucoma. Glaucoma, also known as intraocular pressure, is a disease where the optic nerve of the eye can be damaged over time causing partial or complete blindness. The detection and detention of such diseases will occur through regular eye examinations. Studies show that THC, the active ingredient in marijuana, tends to reduce the eye’s IOP for some time.
Studies have shown that it helps to really lower orthostatic blood pressure with an accurate and methodical approach to the use of medical marijuana. For example, if you stand up quickly after lying down, the blood pressure drops briefly, but then eventually returns to normal. Nonetheless, this does not extend to everyone.
This study shows that cannabis helps restore normal vision by manipulating the endocannabinoid system might, therefore, serve as a therapy to restore normal vision and protect the retina.
Also mentioned in this research that cannabinoids have the potential of becoming a useful treatment for glaucoma, as they seem to have neuroprotective properties and effectively reduce intraocular pressure.
Currently, one way of controlling glaucoma and avoid vision loss is to lower the pressure in your eye. Depending on the type of glaucoma and how serious it is, your ophthalmologist can treat glaucoma with medication such as prescription eye drops or surgery.
There are a lot of CBD products entering the market, but it is best to talk and consult with the doctors.
