Is it safe to use circle lenses to make the eyes look bigger?

The United States Food and Drug Administration prohibits sale of any contact lenses that are not prescribed by eye care professionals, specifically optometrists, opticians, and ophthalmologists (Eye M.D.'s). Contact lenses, especially those like circle lenses that are not personally fitted to your eyes, can cause blurred vision from corneal swelling, pink eye, painful abrasions of the cornea, and corneal ulcers which could perforate the eyeball. Circle or "cosmetic" lenses are particularly prone to cause such problems because they are large and they have very limited permeability to oxygen. Although sale of contact lenses without professional care is illegal, there are hundreds of sites on the internet that sell contact lenses without prescription. Do not take chances! Obtain your contact lenses legally through an eye care professional.
