My left eye is becoming sqeezed?

Blepharospasm or: Other conditions that may make the eye smaller like a long standing retinal detachment that may make the eye phthisical (smaller with low pressure). Or it may be a droopy eyelid, have an ophthalmologist check it.

Pressure sensation??: You need an examination, to screen for glaucoma and dry eye, as well as getting a prescription upgrade. The sensation "squeezed" may represent eye strain, and a need for better lighting and stronger glasses. Over-the-counter artificial tears will not hurt and may help a little. See your ophthalmologist.
