Overview of vision correction methods for myopia

In today’s digital age, with the widespread use of the Internet and smartphones, it is no exaggeration to say that people are in constant contact with electronic devices. This constant strain on our eyes has contributed to an increase in vision problems.
Fortunately, the options for correcting myopia are expanding. In addition to traditional solutions like glasses and contact lenses, newer methods such as LASIK (a surgical procedure to correct vision) and orthokeratology (a non-surgical treatment using special lenses worn overnight) are gaining attention. Orthokeratology lenses, worn while sleeping, allow for clear vision during the day without the need for corrective eyewear.

Principle of myopia correction

Altering light refraction

Glasses, contact lenses, orthokeratology, and LASIK each use different methods to correct myopia.

To correct myopia, the way light is refracted must be adjusted so that it focuses correctly on the retina. There are two primary approaches to achieve this.

How glasses and contact lenses work

Altering light refraction before it reaches the retina

For glasses or contact lenses, a concave lens (used for myopia) is placed in front of the cornea to focus light properly onto the retina.

How orthokeratology and LASIK work

Altering the refractive index of light by reshaping the cornea

With orthokeratology lenses and LASIK surgery, the cornea is reshaped (flattened) to adjust the refractive index of light, helping it focus properly on the retina.

Comparison of various myopia correction methods: advantages and disadvantages

Each of the four myopia correction methods – glasses, contact lenses, orthokeratology, and LASIK – has its own distinct characteristics, along with distinct advantages and disadvantages.

It is important to consult with your local ophthalmologist or clinic to determine the ideal treatment option based on your eye condition and lifestyle.
