There many decent DIY repair kits...Loctite and Permatex come to mind...and they are a one part epoxy type kit...no mixing. (Sold at most auto parts supply and hardware stores)
DIY or seeking professional service...It's a good idea to get it repaired as soon as possible. Driving the vehicle with a chipped windshield can lead to cracking.
Most importantly: A windshield is also part of a vehicles structural/strength architecture.
Water is a chip's worst enemy. It will get into the chip, pulled in by surface tension. If the chip goes all the way through to the safety-glass lamination, water can delaminate the glass from that membrane. Eventually, the membrane will fog, with no way to remove it. Water can freeze in the chip, causing a larger flaw or even a crack to occur. Water can carry dirt into the crack...again with no way to remove it. All can lead to reduced visibility....or worse!
A DIY'er kit, or even a Pro's repair (usually w/warranty---and not too expensive), could leave a visible flaw...at least the chip has been sealed from environmental contaminates, and reduced the chances of a chip enlarging/cracking. This, as it so happens, should return the integrity/safety of the windshield, IMO. Unless you deem a replacement windshield is in order [$$$]
Just a few thoughts...hope it helps some.
