Silicon Simplicity

In 1960, a Spanish ophthalmologist, Jose Barraquer, introduces the Lasik technology for the first time. By developing the first microkeratome which was used to change the shape of cornea, he invented the helpful aid to people who lacks of visibility. In the old days, spectacles are the only tool for people to view more clearly. As the time goes, contact lenses were the best alternatives for people who wanted to get rid their spectacles.

Lasik treatment is a preoperative choice and is digit of the most favourite methods to precise your vision. It is an modern laser exteroception rebuke machine for nearsightedness, farsightedness and astigmatism. During the communication and surgery a anorectic surface is created in the strained or scraped cornea by using either a microkeratome steel or a femtosecond laser. The doc who is performing the surgery would crimp backwards the surface then would vanish the corneal paper using an excimer laser surgey.
However, these contact lenses are not always the convenient option since a lot of care should be taken when people decide to use them. The size of contact lenses is so tiny that people would have chance to lose them. They also should be taken carefully whenever you need to wear it to your eyes, so it wouldn’t drop onto the floor and carelessly damaged itself. Contact lenses are not available to wear all day long since you need to put it off when going to sleep. (more…)

It may not be as high-tech as Jordy’s visor in Star Trek but a research group in Australia has created a ‘bionic’ eye that can restore partial vision to those with degenerative vision loss.

It consists of a miniature camera, mounted on glasses, that captures images and sends them to a processor the wearer keeps in their pocket.

The processor then transmits a signal wirelessly to a unit implanted in the eye which will directly stimulate surviving neurons in the retina, signalling an image to the brain.

Those using the bionic eye will not have perfect vision restored, but it is hoped they will be able to perceive points of light in their field of vision which the brain can then reconstruct into an image.

It is refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed.

Those with myopia see near objects clearly but far away objects appear blur.

Classification:

Myopia has been classified in various manners.

By Cause:

•Axial myopia: an increase in the eye’s axial length.

•Refractive myopia: condition of the refractive elements of the eye.

Curvature myopia: excessive, or increased, curvature of one or more of the refractive surfaces of the eye, especially the cornea.

Index myopia: variation in the index of refraction of one or more of the ocular media.

By Clinical Entity:

•Simple myopia: optically too powerful for its axial length.

•Degenerative myopia/ malignant/ pathological/progressive myopia: characterized by marked fundus changes, such as posterior staphyloma, and associated with a high refractive error. (more…)

Once we have to use something to protect our sight or to help us in reading, we could choose contact lens instead of glasses. You do not have to use a frame. There are minus of using contact lens. Your eyes may be sensitive so your eyes can be red and dry. Therefore you must be uncomfortable using them. But do not worry about the matter.
