Myopia, also known as nearsightedness, is a common eye condition that affects about 25% of the world's population. It occurs when the eye is too long from front to back, or the cornea (the clear front part of the eye) is too curved. This causes light to focus in front of the retina, instead of on it, which results in blurry vision for distant objects.

​

Myopia is usually diagnosed during childhood or adolescence. It can progress rapidly during these years, but it typically slows down or stops in adulthood. There is no cure for myopia, but there are a number of ways to manage it.

​

The goal of myopia management is to slow the progression of the condition and to prevent or reduce the need for glasses or contact lenses in the future. There are a number of different approaches to myopia management, and the best approach for you will depend on your individual needs and circumstances.

​

Some of the most common methods of myopia management include:

• Wearing glasses or contact lenses: This is the most common way to correct myopia. Glasses or contact lenses can help to improve vision and make it easier to see distant objects.

• Orthokeratology (Ortho-K): Ortho-K is a type of contact lens that is worn overnight. It reshapes the cornea, which can help to improve vision and reduce the need for glasses or contact lenses during the day.

• Atropine eye drops: Atropine is a medication that can slow the progression of myopia. It is typically used in children and adolescents.

• Spending time outdoors: Spending time outdoors, especially during the day, can help to slow the progression of myopia. The exact mechanism is not fully understood, but it is thought that sunlight may help to regulate the production of the eye's growth hormone.

• Reduced near work: Reducing the amount of time spent doing near work, such as reading, writing, or using electronic devices, can also help to slow the progression of myopia.

• Diet and lifestyle: There is some evidence that a healthy diet and lifestyle may help to slow the progression of myopia. This includes eating plenty of fruits, vegetables, and whole grains, and getting regular exercise.
