At FL280; First Officer pilot flying smelled and visually saw smoke coming from underneath his glare shield. We donned oxygen masks and made a left 180 degree turn back to ZZZZ. [We requested priority handling with ATC] at that time. Shortly after; ZZZZ1 seemed to be a better choice and it became our divert. Somewhere in the descent the smoke seemed to stop but we maintained masks on. We asked for Runway XX and were given radar vectors which we backed up with the RNAV XX. The weather was 3500 broken and we were able land in VMC. I stopped the aircraft on the runway and allowed the CFR (Crash Fire Rescue) to visually look over aircraft prior to executing a 180 degree turn to taxi back to our ramp. Remainder was uneventful.
Shortly after reaching cruise FL280 with AP (Autopilot) and AT (Auto Throttle) engaged; I noticed smoke coming from under the glare shield. My gasper quickly blew the smoke into my face. I immediately said smoke out loud and donned my mask and goggles. I could visually see the smoke continue into the cockpit for what seemed like 2-3 minutes. The Captain donned his smoke mask and we both established communications. We immediately [requested priority handling with ATC] while making a U-turn back to ZZZZ initially. After we had the aircraft pointed back to ZZZZ; we decided ZZZZ1 was closer. We checked [the weather] at ZZZZ1 and made the decision to proceed to ZZZZ1. ATC was helpful in providing vectors and a weather report. We loaded the RNAV approach to Runway XX; the only IAP (Instrument Approach Procedure) available to the closest runway to us. We landed uneventfully. Upon landing; we noticed the smoke had dissipated so we elected to taxi back to the parking ramp once CFR (Crash Fire Rescue) had completed an external inspection for smoke or fire.
B757 flight crew reported smoke and fumes in the cockpit resulting in a diversion to the closest suitable airport.
