What effect does not not using myopia glasses have on eyes ?

Not using myopia (nearsightedness) glasses when they are prescribed can have several effects on the eyes:

Blurred vision: Myopia causes distant objects to appear blurry. When myopia glasses are not used, the individual will continue to experience blurry vision, making it difficult to see objects and details at a distance.
Eye strain and fatigue: Straining to see distant objects without proper correction can lead to eye strain and fatigue. This can result in symptoms such as headaches, tiredness, and discomfort in and around the eyes.
Squinting: Without wearing myopia glasses, individuals may unconsciously squint to try to see things more clearly. Squinting narrows the opening through which light enters the eye, and while it may temporarily improve vision, it can strain the eye muscles and exacerbate the problem.
Reduced visual acuity: Over time, not wearing myopia glasses can lead to a decline in visual acuity, as the eyes are not receiving the clear images they need for proper visual development.
Progression of myopia: There is evidence to suggest that not wearing myopia glasses can contribute to the progression of myopia. Uncorrected myopia can lead to axial elongation of the eyeball, causing the condition to worsen over time.
Reduced academic and occupational performance: In children and students, uncorrected myopia can affect academic performance. Difficulty seeing the board, reading, or participating in activities requiring clear distance vision can hinder learning and development.
Safety concerns: Uncorrected myopia can affect safety, especially when driving or engaging in activities that require clear distance vision, such as sports.

It’s essential to follow your eye care professional’s advice and wear your prescribed myopia glasses as directed. Regular eye examinations are crucial to monitor any changes in vision and update the prescription as needed. If you experience any issues with your vision or have concerns about your eye health, consult an eye care professional for a comprehensive eye examination and appropriate guidance.
