Reading glasses can be good for your eyes if they are prescribed by an eye doctor and used correctly. As we age, our eyes naturally lose their ability to focus up close, a condition called presbyopia. Reading glasses are designed to help people with presbyopia see clearly up close, by magnifying the text or image being viewed.
Wearing reading glasses that are prescribed to the appropriate strength can reduce eye strain and fatigue when reading or performing other close-up tasks. This can help prevent headaches, blurred vision, and other discomforts associated with eye strain.
However, it's important to note that using reading glasses without a prescription, or wearing glasses with the wrong strength, can actually harm your eyes and make your vision worse. Therefore, it's always recommended to consult with an eye doctor before using reading glasses or any corrective lenses.
