My Vision Problem

I have been experiencing some difficulties with my vision lately, and I recently went to the doctor to get my eyes checked. The doctor told me that I have a slight myopia and presbyopia, which means I need to wear glasses or contact lenses to see clearly. I am disappointed because I have always hated wearing glasses, but I understand that it is necessary for my health and well-being. I hope that in the future, we will have more effective and comfortable methods of correcting vision problems. In the meantime, I will continue to wear my glasses or contact lenses and take care of my eyesight.
