One topic of life science I’d like to explore is the human eye. Light has both wave and particle-like properties. When resistance (a resistor) is placed against the electrical current, the resistance heats up and glows, converting electrical energy into light energy. The light energy then radiates photons towards the human eye, where it is reflected onto a focal point. This energy then radiates down a signal pathway consisting of neurons. Simply put, the brain creates an image based on the pattern of lights we are receiving, allowing us to see. The most fortunate thing that I believe people take for granted is the ability to see. Eye disease symptoms include hazy vision, eye pain, light sensitivity, and seeing flashes of light at a young age. It is not uncommon to see adolescents wear glasses in today’s age. One research that has been pointing to this is the dangers of blue light reflecting off screens. Short-wave blue light with a wavelength between 415 nm and 455 nm is closely related to eye light damage. Visible blue light is already between 490 and 450nm. The human eye creates a picture that may last a second, but the mistreatment of our eyes will last for a lifetime because our bodies do not reproduce eye cells.
