Is it normal to want to squint when wearing contact lenses?

Dryness, fit, debris: Before having Lasix (furosemide) done, i too squint while wearing contacts. It was often due to dry eyes, poor fit of contacts, irritants on the eye or contact, protein buildup on the contact, lint, tear within the contact, and other causes. Since lasix, (furosemide) it took about 2 months to break the habit of squinting and rubbing my eyes.
