Since we have two eyes, we can set the focal point for each eye differently: one more for distance, the other more for up close. This can typically be tried in contact lenses to see if it works for you. Traditionally referred to as monovision, the blended vision concept has limitations, with effects on depth perception and ghost images. If appropriate, Dr. Hamilton may suggest you try blended vision with contact lenses prior to undergoing a blended vision treatment with SMILE, LASIK, EVO Visian ICL . Blended vision can also be employed with cataract surgery or refractive lens exchange. Dr. Hamilton will suggest this if he feels it is the best option for your particular situation.
