Laser As Applied in LASIK Eye Surgery

The first application of lasers in our daily lives of the general population was the supermarket barcode scanner. It was introduced in 1974. The laserdisc player was introduced in 1978, it the first successful consumer product to include a laser, despite the fact the compact disc player was the first laser-equipped device to become truly ordinary in consumers' homes since in 1982, followed soon by laser printers. When lasers were invented in 1960, they were called "a solution looking for a problem". Since then, they have become ubiquitous, finding function in thousands of highly varied applications in every section of modern society, including consumer electronics, information technology, science, industry, law enforcement, entertainment, military and medicine.

Laser is a device that discharges light known as electromagnetic radiation through a process called stimulated emission. Laser light is usually spatially consistent, which means that the light either is emitted in a fine, low-divergence beam, or can be transformed into one with the help of optical apparatus such as lenses. In general, coherent light typically means the source produces light waves that are in step. They have the equivalent frequencies and indistinguishable phase. The coherence of conventional laser emission is a typical characteristic of lasers. Most other light sources emit incoherent light, which has a point that varies randomly with time and position. Normally, lasers are thought of as emitting light with a narrow wavelength spectrum or monochromatic light. This is not true of all lasers, nevertheless: some emit light with a broad spectrum, while others emit light at multiple distinct wavelengths simultaneously.

Laser in situ keratomileusis, LASIK, well known name in refractive eye surgery, provides vision improvement through the use of a laser by restructuring the cornea and altering its focusing power.  Since 1993, LASIK has been done in the U.S. on millions of patients with the use of a wide array of lasers.  This process can be used to tweak myopia or nearsightedness, hyperopia or farsightedness, and astigmatism or misshapen cornea. There are now more than a few different lasers that have received FDA consent for visionlaser.com.au LASIK eye surgery.  There are diverse lasers for use in myopic and hyperopic patients, but most allow for correction of astigmatism. 

One of the supreme enemies of our eyes is the sun. Similar to the skin, eyes are damaged by UV rays coming from the sun, whether it is a cloudy or a clear and sunny day. Sunglasses should at all times be worn in daylight hours when you are outside and you need to be certain that the sunglasses you choose offer UV ray protection. There are many sunglasses sold which are just colored glass and do not really protect your eyes, they simply offer shade from the brightness. Take care of your eyes, we only got a pair.
