Maybe: Your entire body will be tired, including your eyes. Many people get red eyes from decrease lubrication (tears). Difficulty in concentration and reading speed will also decrease. When tired your eyes can have trouble focusing. Some people have mild strabismus, and see intermittently double. Your eyes and your body should feel better after you sleep. Good night.

It depends: For the most part, no. However, your general health is important for overall eye health and eye sight. Your eyes may feel dry after being up all night, and this may blur the vision. Good sleep is essential for optimal brain function.

This, along with headache, is the most common early symptom of chordoma.

Maybe: The blackness should be differentiated from blurring. True blackness is a different problem and should be addressed immediately. The blur is usually caused by glasses or dry eyes. These are usually easy to remedy by on ophthalmologist.

No: Glasses are designed to improve the focus of the eye and improve clarity. Sometimes patients who start wearing readers feel that their near focus becomes more difficult and to a certain extent this is true. But eventually, readers become essential whether glasses are used initially or not.
