Hello, It sounds like you are experiencing a decrease in your vision and seeing wavy lines. This could be a sign of an eye condition called astigmatism. Astigmatism is caused by an irregularly shaped cornea or lens in the eye, which causes light to be focused unevenly on the retina. This can cause blurred vision, double vision, and wavy lines. If you are a college student, it is important to get your eyes checked regularly. If you have not had an eye exam recently, it is recommended that you make an appointment with an optometrist or ophthalmologist as soon as possible. They will be able to diagnose any underlying conditions and provide treatment options if necessary. In the meantime, there are some lifestyle changes that can help improve your vision. Eating a healthy diet rich in vitamins and minerals can help improve your overall eye health. Additionally, taking regular breaks from screens and avoiding bright lights can help reduce strain on your eyes. I hope this information has been helpful!
