Comparative Effect of Cobra Venom and Opiates on Vision

By Michael Allen

It is believed by researchers that cobra venom is responsible for enhanced visual focusing. Cobra venom, through the pain centers of the brain eased feelings of discomfort and in patients who have malignant eye disease the reduction of pain allows for better visual focus. In fact, cobra venom worked much like the opiate family of drugs including; heroin, codeine, and morphine for pain relief, but these drugs did not have the same ability to improve vision. The cobra venom pain-relieving properties actually come on more slowly than opiates and the effects lasted longer, all the while improving patient's sight (Macht, 1939).

Method

Thirty-five college students and members of the school board were tested by standard reading charts for visual acuity in both eyes. Visual readings were taken before and after administration of morphine, codeine, heroin, dilaudid, pantop and cobra venom. Each individual was tested for white, blue, red, and green receptivity. Results were collected from each individual and visual sharpness was calculated with and without each drug. Statistics were compiled.

Results

The results showed that morphine increased vision slightly but in full doses created myosis or contraction in the iris. Codeine, heroin, dilaudid, and pantop did not increase visual acuity at all. However, cobra venom once injected increased the vision in 75% of individuals tested. Cobra venom actually increased a person's field of vision and visual focus. As well, visual sites receptive to red and greens were especially enhanced followed by blue then white (Macht, 1939).

The findings pointed to cobra venom easing the conditions of diseased eyes through pain relief. While opiates generally narrowed the field of vision in patients, cobra venom has the opposite effect and widened patient's field of vision. It is theorized that increased blood circulation to the retina is responsible for the increase of visual range. It is also theorized that cobra venom enhanced circulation in the parts of the brain that control vision, thereby, improving receptivity to colour (Macht, 1939).
