As an optometrist with over a decade of experience in vision care, I can tell you that wearing prescription glasses when you don't need them can lead to a few discomforts. If the glasses have a strong prescription that is not suited to your eyes, it can cause disorientation and make it difficult for you to focus properly. This can result in headaches and eye strain if worn for an extended period. However, wearing glasses with the wrong prescription will not damage your eyes in the long term, though it's not advisable to do so. It's important to wear glasses that are prescribed specifically for your eyes to ensure clear and comfortable vision. Using someone else's glasses, especially if they have an outdated prescription, can lead to discomfort and may even affect your vision negatively over time. read more >>
