Thanks for reading too, the exercise would depend on reason for which the specs were prescribed. For some binocular vision anomalies some exercise could help increase the strength of whatever is causing the issue with the vision and eventually one may not need the specs however if it is with refractive error then whiles exercises may help improve vision in general it cannot take the place of the glasses. If you want other alternatives to wearing glasses, we would be writing about these in our subsequent posts so you can explore you options. We would also be writing about refractive errors shortly so you could understand better why exercises cannot take the place of your spectacles in those conditions. Feel free to let us know if you have any other problems. We are also joining @steemstem on discord so you can reach out if anything.
