THE GREAT WORKS OF RETINA

The human eye contains a retina - a membrane with about 120 million cells called photoreceptors, which soak up like a towel, light rays and convert them into electric signals. Your brain understands and explains these signals as visual images. People who believe that life forms became more complex over a long time have argued that where the retina is placed in the eyes of an animal with backbones, creatures with a spine of boldness also called backbone, proves that the eye had no designer.

The retina of backbones is inverted, placing the photoreceptors at the back of the retina. To reach them, light must pass through several layers of cells. According to those who believed that things slowly change for the better over time concerning living things called evolutionary biologist, this arrangement scatters the light, making our vision less explained than it might be.

The evolutionists, who believed that life forms became more complex over a long time, claim that the inverted retina is especially advantageous for vertebrates with small eyes, no design. Revelations by scientists even described it as a functionally stupid upside-down direction of information meeting. However, further research reveals that the photoreceptors of the inverted retina are ideally placed next to the pigment epithelium - cell layer that provides oxygen and nutrients vital to keen sight. In fact, some experts say that sight would be far less efficient if this layer of cells were in front of the retina.

The inverted retina is especially advantage-giving for animals with backbones with small eyes. Scientists discovered that between the lens of the eye and the photoreceptors, there must be a certain distance to get a sharp image. Having this space filled with nerve cells means an important saving of space for the animals with backbones.

Also, with the nerve cells of the retina tightly packed and close to the photoreceptors, analysis of visual information is fast and reliable.

What do you think? Is the inverted retina an inferior structure, a product of mere chance? Or was it designed?
