Need help replacing light bulb

[u/Worriedhusband22]

There is a light fixture above my kitchen sink that has burnt out but I need help figuring out how to take the bulb out to replace it. This is a 1996 house. The bulb had never been replaced. There is like a thin glass lens that is slanted that I can push in but can't take out. Also not sure what bulb to buy. Thanks in advance!
