After the age of 40, the ability to transition between distance and near vision becomes much more difficult. Progressive glasses provide you the ability to use different parts of the lens to see near and distance. However, not all progressives are created equal. If you have had difficulty adjusting to progressives in the past, or have tried progressives elsewhere, the technology may not have been compatible with your visual needs. Newer technologies have made progressives much more comfortable providing a wider field of view and more comfortable adaptation.
