• Entropion, ectropion, extrusions, chalazia, recurrent styes, dry eye, glaucoma, history of recurrent corneal erosions.
• Any previous, or planned, ocular or intraocular surgery (e.g., radial keratotomy, PRK, LASIK, lid procedures, cataract surgery, retinal surgery, etc.).
• A history of amblyopia, strabismus or binocular vision abnormality.
• Any ocular infection or inflammation.
• Any ocular abnormality that may interfere with contact lens wear.
• Use of any ocular medication, with the exception of rewetting drops.
