Vision is one of the senses which allows us to see the world around us. The eyes contain more than half of the sensory receptors in the human body which lets us perceive and send visual information to our brain. A person can see normally when the eye focuses light onto the retina from the front or behind and can see things both close up and far away very clearly.¹

When a person has normal vision, the image that they see is tightly focused onto their retina. Myopia is a condition in which the point of focus is located in front of the retina, which causes objects that are further away to look blurry. Myopia is commonly known as near-sightedness, which causes distorted vision for objects that are further away yet appear clear when viewed from a close distance.²

Myopia places a tremendous burden not only on the healthcare system but also on the economy and the overall quality of life. It is a growing concern for public health on a global scale, and it calls for the implementation of therapies to halt or postpone the disease's development and progression. The notions of myopia, as well as the methods used to treat and prevent it, are continuously evolving in response to new information and developments in medical science. Myopia has been a growing worry due to the increase in unawareness.²

It is estimated that around 1.4 billion people in the world suffered from myopia in 2000, and the number will reach 4.8 billion by 2050.³ According to the World Health Organization, myopia is one of the chief causes of vision impairment and blindness globally. Moreover, the prevalence of myopia is constantly increasing. Individuals with myopia can be divided further into two categories: those who have low to moderate degrees of the condition (also known as "simple" or "school" myopia, 0 to -6 dioptres) and those who have extreme or pathological myopia (more than -6 dioptres).⁴ Myopia that is only simple can be rectified with eyeglasses or contact lenses, but myopia that is pathological, often known as "severe" myopia, is frequently connected with disorders that could lead to blindness, such as retinal detachment, macular degeneration, and glaucoma.⁴

Myopia can be fixed with concave glasses lenses or contact lenses. Use of corrective methods modifies the eye function and changes the point where light falls on the retina. This results improvement of the vision which was earlier blurred. Use of prescription glasses and lenses bends the light in such a manner so that it can focus on the right spot on the retina. In some cases, surgery can be used to fix it to change the way the eye works, but it doesn't change how long the eyeball is. Distance vision can be restored with the aid of treatments and management techniques. A timely intervention helps manage myopia efficiently.⁵
