When putting things into perspective if the problem is complex, the surgery may be just as complex. For instance, when you were a young child who got cuts and bruises it was probably treated with warm water, soap and a plaster. In the case of brain surgery, it is more challenging and complicated. With technology advancing the complex problem doesn’t always require a complex solution. Things have simplified in modern times and conditions that were difficult or impossible to treat once can be resolved easily, sometimes with just an injection.

With sophisticated laser technology being developed, people with shortsightedness, long sightedness or astigmatism are able to correct poor vision. The reality now is you can have laser eye surgery in the morning that by night you can see everything rather clearly. This is how simple laser eye surgery has become. If you want to know how it works, you need to understand refractive error and what it actually is.

The term refraction reflects how your vision works. Light passes from one object to another, and when the rays enter the prism it is bent or refracted and then directed in different directions. This process of light rays allows the light to focus on a single point in the retina, which is found at the back of your eye. It is converted to an electric signal, sent to your brain through an optic nerve and you see the image translated right in front of you. How clear the image is depends on the cornea’s health and functionality.

When there are common problems associated with this, it is referred to as refractive errors. If the eyeball is too long you will experience shortsightedness, where the cornea is curvier than normal focusing too strongly. In the instance of shortsightedness the eyeball is too short. The light focuses not on the surface of the retina, but rather behind it making the power too weak.

People with astigmatism have a distorted lens. The light is refracted not to one point, but two focal points. And Presbyopia is a condition experienced by older people. There is a stiffening of your lens which leads to impaired vision.

To banish vision problems completely, consider Lasik treatment in Dubai. It is nothing short of impressive and you will soon have clear vision that will make you wonder how you lived without it for so long.
