Bump on the Eyeball

Bump on White of Eye Cancer (BOWCO)

The term “boomerang” is used when a person has been hit again or again by something. This phenomenon occurs because the brain cannot accept such behavior. It’s like hitting yourself over and over again with a hammer until it breaks.

The same thing happens to your eyes; they are constantly being struck by light rays from the sun, which causes them to burn up and eventually cause blindness. If left untreated, the damage will become irreversible.

In order to prevent blindness, the retina must heal itself. However, if there is no inflammation present at the site of injury, then healing takes much longer than it would without any irritation. When this happens, the damaged tissue begins to die off and fall apart.

Eventually all that remains is a blackened area where there was once healthy tissue.

When the optic nerve is injured, it sends signals to the brain telling it to blink rapidly. These signals are transmitted through nerves called nociceptors. Nerves transmit electrical impulses across a gap known as a synapse.

A neuron receives these impulses by making chemical changes in its membrane. One type of change involves changing the shape of its outer layer called myelin sheath. Myelin makes the transmission of signals much faster. Without myelin, the signal is slowed down and distorted. The brain does not understand the distorted signal and assumes that the eye is in danger. It then tells the eye to blink rapidly in order to “wash away” the irritant.

This condition can be prevented by wearing good quality sunglasses that block both UVA and UVB rays. It is important to remember that it does not matter how expensive or “cool looking” the shades look. What matters is their ability to protect your eyes.

In addition, it is important that children wear eye protection whenever they are engaging in any kind of activity that might result in a foreign object entering their eye (e.g. playing sports, fighting, etc).

However, as people get older it becomes more difficult for them to remember to put on their eye protection. This is why it is so important to remind them constantly.

Tobacco smoke contains a lot of different chemicals, many of which have a negative impact on your vision. According to the National Eye Institute, smoking decreases your eyes’ ability to flush out toxins. It also increases pressure inside your skull, which can lead to glaucoma.

When this happens, fluid cannot drain properly from the eye and it begins to damage the optic nerve.
