Egress Windows.  Have you heard of them?  Here is a description from Waters Basement Services:
Adding an Egress Window not only adds enjoyable living space to your home, but it can make an incredible difference in the livability of your basement by bringing natural daylight into your living space. An Egress Window provides an accessible escape route in case of an emergency. Unique Grip/Step design features a convenient handle and gusseted step to meet building code requirement for Egress.

An optional dome cover is available to protect the window well opening and to reduce the accumulation of snow, leaves, and debris inside the well.
