I just bought a glass. In fact, I do not intend to wear the glass often. Maybe I wear the glass when I need it. For my left eye: 150 and my right eye: 50. I can still see the things quite clear. Is it harmful to my eyes if I simply wear glass when I need it? Would the eyes deteriorate?

Spectacle wear when needed usually will not lead to deterioration of vision, but it will possibly affect the clarity and comfort of vision. Tiredness, headache and blurry vision can be some possible symptoms of uncorrected refractive error. Age and visual needs also affects the needs of full time wear of spectacle. If you have further queries, a comprehensive eye examination is suggested.
