Wearing glasses can help correct the refractive error associated with myopia (nearsightedness), but it will not reverse any structural changes that might have occurred in the eyes due to long-term untreated myopia. Myopia is typically caused by the eyeball being too elongated or the cornea having too much curvature, which causes light to focus in front of the retina rather than directly on it, resulting in blurry distance vision.
Glasses and contact lenses work by changing the way light enters the eye, so it correctly focuses on the retina, providing clear vision. However, they do not alter the shape of the eye or reverse any elongation that might have already occurred over the years.
Long-term untreated myopia can lead to potential complications and changes in the eye, such as:
Macular Degeneration: Myopia is associated with a higher risk of developing age-related macular degeneration (AMD) later in life, which can cause vision loss in the central part of the visual field.
Retinal Detachment: Severe myopia can increase the risk of retinal detachment, where the retina pulls away from the back of the eye, potentially leading to vision loss.
Glaucoma: There might be an increased risk of glaucoma in individuals with high myopia.
Cataracts: Myopia has been linked to an earlier onset of cataracts, clouding of the eye's lens, which can cause vision impairment.
While wearing corrective glasses or contact lenses can significantly improve the quality of vision for individuals with myopia, it is crucial to have regular eye checkups with an eye care professional. They can monitor the eyes for any potential complications and provide appropriate recommendations to manage the condition.
In cases of progressive myopia, certain treatments like orthokeratology, atropine eye drops, or specialized contact lenses may be considered to slow down the progression of myopia in children and teenagers. However, these treatments might not be effective for adults or may have limited impact on already established structural changes.
If you have concerns about your vision or myopia management, it's essential to consult an optometrist or ophthalmologist who can conduct a thorough eye examination and provide personalized advice based on your specific condition and needs.
