An optical glass bow dome, no, and there are a couple of reasons for that.

1. There's no reason for it - unlike "Voyage to the Bottom of the Sea", there's nothing to see at the depths submarines operate at.

2. Glass properties aren't strong enough to withstand the constant pressure changes and operating environments submarines are routinely exposed to.

3. Resonance - glass resonates when a fluid is moving over it, causing a loud, low frequency.

4. Collision - any collision will likely occur at the bow, and glass isn't exactly that strong.

Glass Reinforced Plastic (Fiberglass) domes have been used on submarines for over 40 years, but their downside is that if there's an underwater collision (uncharted object, e.g.) the damage caused is much worse than if the boat had a steel dome. Both types of incidents have already happened in the U.S. fleet; my own boat hit an underwater mountain in '77, crushing the steel dome, but saving the boat from much worse damage. By contrast, the USS San Francisco, which hit an uncharted mountain several years ago with at GRP dome, lost crew and suffered serious damage as a result.

Technically, you could probably use a thick, ballistics type clear glass for a dome, but again, there's no reason for it, as the bow dome houses the main Sonar arrays.
