Sale Contact Lens No Prescription

When a prescription is necessary
If you are using contact lenses for medical purposes, consultation with a doctor is essential. The doctor would suggest you a lens most appropriate for your eye problem. The doctor would also examine your eye cornea to get information about the size and diameter of the lens. It is essential for you to get your eyes examined every time you buy a lens so that the doctor could tell you the exact status of your medical problem. The doctor may suggest you a new prescription with lenses of a different power.
However, if you are using a contact lens only for decorative purposes or just want to sport colored lenses you need no new prescription if you have one already. The size of cornea and angles do not change with age and you need no prescription for colored contact lenses if you already have this information.
