Tramadol Cheap HOW THE HUMAN EYE WORKS
line

1

Light rays enter the eye through the cornea, the clear front “window” of the eye. The iris of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the back of the eye by adjusting the size of the pupil automatically.

2

The pupil dilates (enlarges) and constricts (shrinks) like the aperture of a camera lens as the amount of light in the immediate surroundings changes. In dark conditions, the pupil widens. In bright conditions, the pupil constricts.

3

After passing through the iris, the light then goes through the eye’s natural crystalline lens. Just like the lens of a camera, the lens of the eye focuses the light or an image onto the retina. The lens becomes thicker to focus on nearby objects and thinner to focus on distant objects.

The retina acts like an electronic image sensor of a digital camera, converting optical images into electronic signals. The optic nerve then transmits these signals to the brain.

Overexposure to UV radiation increases your risk of getting cataracts and macular degeneration.

If you spend a lot of time starring at digital screens from laptops to smartphones or even long periods focusing on any one thing, you sometimes forget to blink and your eyes can get fatigue.

Try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This can help reduce eye strain. Besides that, at least every 2 hours, get up and take a 15-minute break.
