Blurry vision

Ive been getting alot more blurry visions now🙏🏻 will go to an optician next week to measure my eyes because my sight just gets worse and worse: im planning on buying new glasses😃 i want small black square glasses becauss big round glasses like i do now makes my face appear more round. But the blurry visions ik talking about are not necessarily because of my glasses but i feel blurry and dizzy, I feel just like fainting when i do. Pray for me people!
