Extended range of vision (EDOF)
An extended-depth-of-focus (EDOF) lens aims to add useful range. The exact model, target and health of the eye determine whether it is an option to discuss.
EDOF means a longer zone of useful focus rather than one narrow focal point. Different EDOF lenses use different optical designs and reach different working distances. Many are designed around distance and intermediate tasks; reading glasses may still be needed for small print or sustained near work. Check the exact model and the distance used in its study.

Detailed explanation of this option
Near glasses may still be needed. Whether they are needed for a quick phone message, a menu or an hour of small print depends on the model, intended target, residual refraction, lighting and what you call comfortable reading.
Do not assume that every EDOF lens is safer, gives the same glasses independence or has the same night-vision profile. “Pseudoaccommodation” only means functional range created without restoring the natural lens's autofocus; the term alone does not prove either a benefit or a worsening. Compare the exact lens with its control.
Because this category combines a wide variety of different technologies, visual experience can vary between specific lens models. See the IOL Options section for more detail.
