you are experiencing the symptoms of Presbyopia, there are three lens options:

• Reading: good for near vision only. If you look up at a computer screen or across a room, your vision will blur while wearing glasses.
• Bifocal: an older option wherein the lens is divided into two distinct sections for near and distance, but provides no correction for mid distance.
• Progressives : ideal for all distances, as the lens corrects near, distance and in-between vision.
