The invention discloses UV (ultraviolet) glue water, a polyurethane acrylate oligomer and a preparation method of the polyurethane acrylate oligomer. The preparation method comprises the steps of S1, preparing an intermediate product A by virtue of phenyl glycidyl ether and acrylic acid; S2, enabling the intermediate product A to react with isophorone diisocyanate to prepare an intermediate product B; S3, enabling bisphenol A polyoxyethylene ether to react with acrylic acid to prepare an intermediate product C; S4, enabling the intermediate product B to react with the intermediate product C; S5, adding an active diluent, performing reduced pressure distillation, filtering and discharging. A self-healing type polyurethane acrylate oligomer which has relatively high refractive index and relatively low viscosity and does not contain sulfur and halogen elements can be prepared by using the preparation method, wherein the refractive index is more than 1.53; the viscosity is 8000-20000cps at 25 DEG C; moreover, the UV glue water prepared by using the polyurethane acrylate oligomer as a main substance is uniformly coated on a PET (polyethylene terephthalate) base material, and is cured and molded on a molding machine to prepare a prismatic lens; scratches on the prismatic lens can be removed within 1-3 seconds.
