5 Things You Need to Know About
Myopia vs. Astigmatism in Today's World

In our fast-paced world, where screens dominate our daily lives and visual demands are higher than ever, understanding common eye conditions is crucial. Two prevalent refractive errors, myopia, and astigmatism, affect millions of people worldwide. In this blog post, we’ll delve into the differences between myopia and astigmatism, shedding light on five key aspects to help you navigate the world of eye health.

Defining Myopia and Astigmatism​

Myopia, commonly known as nearsightedness, occurs when distant objects appear blurry, while close objects remain clear. Astigmatism, on the other hand, is characterized by an uneven curvature of the cornea or lens, causing distorted or blurred vision at any distance.  Understanding these basic definitions is the first step in recognizing the differences between these two conditions.

Global Impact

The prevalence of myopia and astigmatism has been on the rise globally, with a significant impact on public health. The World Health Organization (WHO) estimates that approximately 2.6 billion people worldwide have myopia. The increasing use of digital devices and changing lifestyles contribute to the growing number of individuals affected by these conditions.

Risk Factors and Prevention​

Both myopia and astigmatism have a genetic component, meaning if your parents have these conditions, you may be more susceptible. However, environmental factors also play a crucial role. Prolonged screen time, inadequate outdoor activities, and poor lighting conditions are risk factors for myopia. Understanding these risk factors empowers individuals to take preventive measures, such as practicing the 20-20-20 rule to reduce eye strain and spending more time outdoors.

Corrective Measures​

Fortunately, there are effective ways to manage and correct myopia and astigmatism. Eyeglasses and contact lenses are common solutions that provide clear vision by compensating for refractive errors. In recent years, advancements in technology have led to the development of orthokeratology and various surgical procedures like LASIK, offering more permanent solutions for those seeking freedom from glasses or contacts.

Atropine eyedrops​

Atropine is a medication that dilates the pupil and temporarily paralyzes the eye’s focusing muscle. This helps reduce accommodation and may slow down the progression of myopia. The exact mechanism is not fully understood, but it is believed to regulate eye growth

Orthokeratology (Ortho-K)

Ortho-K involves wearing specially designed rigid gas-permeable contact lenses overnight. These lenses reshape the cornea temporarily, providing clear vision during the day without the need for corrective lenses. Ortho-K is explored as a method for myopia control, influencing peripheral defocus and the optics of the eye.


MiSight is a type of soft contact lens designed for myopia control. Worn during the day, it corrects vision while simultaneously providing peripheral defocus, aiming to slow down myopia progression. The lenses have a dual-focus design, addressing central and peripheral vision.

Impact on Daily Life

Myopia and astigmatism not only affect visual acuity but can also impact daily activities and overall quality of life. From academic performance to workplace productivity, uncorrected refractive errors can have far-reaching consequences. Regular eye check-ups, especially for children, are essential for early detection and intervention, ensuring that these conditions do not hinder personal and professional development.
