Will not wearing glasses for myopia cause dizziness?

Whether myopia causes dizziness when not wearing glasses depends on the degree of myopia and the visual task at hand. Individuals with mild myopia who primarily engage in near-vision activities typically do not experience dizziness, whereas those with moderate to high myopia or those requiring clear distance vision may feel dizzy. The detailed analysis is as follows:

For individuals with low myopia who only perform close-up tasks such as reading or using mobile devices in daily life, the eye's accommodative ability can compensate for the refractive error, so dizziness generally does not occur. In such cases, the eyes do not need to exert excessive effort to focus, allowing the visual system to remain in a relatively comfortable state, minimizing discomfort.

In patients with moderate to high myopia, or in those with mild myopia performing distance-vision tasks such as driving or viewing a blackboard, not wearing glasses can easily lead to dizziness. The eyes must continuously accommodate to see distant objects clearly, causing excessive tension in the ciliary muscle. This disrupts the coordination between visual signals and the body's balance system, resulting in symptoms such as dizziness and eye strain.

To protect vision, proper daily eye care is essential. After developing myopia, one should have a timely eye examination and wear appropriate corrective lenses as needed. Avoid prolonged continuous eye use; take breaks by looking into the distance every 30 minutes. Maintain correct reading and writing postures, ensure adequate lighting in the visual environment, and reduce the accommodative burden on the eyes.
