World Sight Day

“The only thing worse than being blind is having sight but no vision.”

Every year World Sight Day is commemorated on the second Thursday in October. It is an international event which creates attention vision impairment and blindness. It was founded by the Sight First Campaign of Lions Club International Foundation in 2000. 

We can also call it W.S.D. The international agency for the prevention of blindness is coordinating the world sight day and creates some games for blind kids and motivates them to give gifts and prizes. The main object of this day is to eradicate the blindness from the country and also this day is a hope to reduce the negative effects of blindness and vision loss. 

It can decrease quality of life, reduce economic growth and social development. According to the world health organization 39 million peoples are blind and 246 low vision in the whole world they are living in Low Countries which is 90% blind in the developing world. Blindness is a type of disease which takes attention on this day.

“The eyes are the windows to the soul”


Our eyes are one of our five sense organs. Sight is very important for everyone. Human eyes are known to react by light. 

The human eye is made up of two differently shaped pieces, the cornea and the scalera. The cornea and the scalera are connected by a ring that is called the limbus. The outer part of the eyes which can be seen is Iris. The iris is the colorful part of the eye. In the middle of the pupil there is a black dot, that we called the pupil, which changes the size of the eye. The cornea covers all these elements, which is the outermost covering of the eye. The optical nerves send signals from the eye to the brain.

The outermost part of the eye is composed of the cornea and the sclera. The middle layer of the eye is composed of the choroid, ciliary body and iris. The innermost layer of the eye is the retina, which can be seen with an instrument called the ophthalmoscope.

Our eyes are composed of rods and cones. Rods allow us to see shapes, while cones are responsible for detecting and deciphering colors.

“Our sight is the most perfect and most delightful of all our senses.”

  1. Refractive Errors
  2. Cataract
  3. Diabetic Retinopathy
  4. Glaucoma
  5. Amblyopia
  6. Strabismus


The refractive errors include diseases such as

  •  Myopia

Also known as near-sightedness.

  • Hyperopia

Also known as farsightedness.

  •  Astigmatism

Also called distorted vision at all distances.

  •  presbyopia 

loss of the ability to focus up close,which occurs after the age of 50-60 years. 

These can be corrected by surgery or using contact lenses.


This disease is clouding the eye’s lens. Cataract is not any related eye disorder. It can occur at any age. It could at the time of birth. It can be corrected by surgery and lenses.


It’s a complication of diabetic patients. It is caused by damage to the blood vessels of the retina, the light-sensitive tissue at the back of the eye that is necessary for good vision. It could be cured by good control of blood sugar, blood pressure, and lipid abnormalities. 


When the normal fluid pressure inside the eyes slowly rises, this disease is known as glaucoma. This disease is very dangerous and can result in vision loss and blindness. open angle and closed angle are two categories of this disease. It could be cured by proper medical treatment at the proper time.


This disease is also called lazy eyes. This disease occurs when the eye and the brain are not working together properly, and results in reduction of vision of one eye. It can be cured by medical treatment.


This disease changes or diverts the position of the eyes of the person. It can cause the eyes to cross in (esotropia) or turn out (exotropia). This could be by birth or genetically developed later.
