I would like to order contact lenses from an online supplier and haven't had my eyes tested for 2+ years now. Last time I was checked I was around -1.75 in both eyes. I was just wondering if its safe to assume that I'm still around -1.75 in both eyes and if there is any imminent risk with regards to eyesight by essentially writing my own prescription and wearing them!
