Describe an object that you use every day and could not live without

An object I use every day and honestly could not live without is my pair of glasses. I've worn them since I was twelve, and my current pair is about two years old. They have a thin black frame and fairly thick lenses, because my eyesight is quite poor.

I put them on as soon as I wake up, since without them everything looks like a blurry painting. I wear them all day, to read, to use my laptop, to watch lectures and to walk around the city. At night, I put them on the shelf next to my bed, always in the same place, so I can find them in the morning. I have a spare pair in a drawer, but I find them uncomfortable, so I keep them only for emergencies.

I could not live without them for the obvious reason that I can hardly see. Without my glasses, I cannot read road signs, recognise friends from a distance or even see the board in class. They are also a matter of safety, because crossing a busy road without them would be quite risky. Beyond that, they have become part of my identity. People who know me can't imagine me without them, and when I once forgot them at a friend's house and had to go without for a day, I felt strangely naked and incredibly tired by the evening, because I was straining my eyes all the time.

It makes me think how much we take small things for granted. Glasses are a simple invention, but they change my daily life completely. I'm grateful for them, and I'm very careful not to sit on them or lose them.
