Astigmatisme [Rabun Silau]

Assalamualaikum

It's finally happening to me. I finally have to admit that I have to wear spectacles. It not that I'm near sighted or far sighted, I'm just having some kind of eye sensitivity towards light, especially during the night, in science word...astigmatisme.

Lets review a little bit about astigmatisme...

Introduction
Astigmatism is a mild and easily treatable imperfection in the curvature of your eye. The condition can cause blurred vision.

Astigmatism occurs when the front surface of your eye (cornea) or the lens, inside your eye, has a slightly different surface curvature in one direction from the other. Instead of being even and smooth in all directions, the surface may have some areas that are flatter or steeper. When the cornea has a distorted shape, you have corneal astigmatism. When the lens is distorted, you have lenticular astigmatism. Either type of astigmatism can cause blurred vision.

Astigmatism blurs your vision at all distances. Astigmatism is often present at birth and may occur in combination with nearsightedness or farsightedness. The condition tends to remain constant, neither improving nor deteriorating much over time.

Astigmatism is common and affects most people to some degree. Often it's not pronounced enough to require corrective action. But when it is, treatments include corrective lenses and surgery. [mintak dijauhkan Tuhan operate2 nih]

Signs and Symptoms
Signs and symptoms of astigmatism may include:
  • Distortion in portions of your visual field [don't know what this means]
  • Blurring of vertical, horizontal or diagonal lines [exactly what happened to me]
  • Eyestrain or fatigue [often have this]
  • Headaches [everyday]

Causes

Astigmatism occurs when part of your eye has an irregular shape, resulting in blurred vision. An irregularity in the front surface of your eye (cornea) causes corneal astigmatism. An irregularity in the lens causes lenticular astigmatism.Astigmatism is one type of refractive error. In astigmatism, your cornea or lens is curved more steeply in one direction than in another. Uncorrected astigmatism blurs your vision. Typically, the blurred vision occurs more in one direction than in another — either horizontally, vertically or diagonally.

In most instances, astigmatism is present at birth. Sometimes, astigmatism develops after an eye injury, disease or surgery. Astigmatism isn't caused or made worse by reading in poor light, sitting too close to the television or squinting. [ok...maknanya nengok laptop nih bukan punca sebenar rabun silau nih...hiks]

this is when I finally give up and went to the optometrist and got myself a pair of specially made glasses that cost me RM360. The glasses will be ready this coming X'mas.

Well this is the disability that I newly acquired for myself. Hopefully I recover from it. Just wish it won't get worse. Coz I can't imagine myself...a four eye. Hiks. Until then, take care now bye bye then
