This invention relates to an alignment assisting device for eye drops that is used in combination with an eye drop bottle. The eye drop bottle has a bottle tip. The alignment assisting device for eye drops comprises an outer frame, a reflector, a Fresnel lens, and a fastener. The reflector is inlaid in the outer frame and comprises a transparent substrate and a reflective layer formed on the transparent substrate. Further, the transparent substrate is formed with a first through hole for the insertion of the bottle tip therein. The Fresnel lens is inlaid in the outer frame at a position corresponding to the reflector and is formed with a second through hole corresponding to the position of the first through hole for the insertion of the bottle tip therein. The fastener is disposed to the reflector for fastening the eye drop bottle. Through the combination of the Fresnel lens and the reflector, a user can observe an enlarged image of an eye when dripping eye drops, so as to enhance the accuracy and convenience. Besides, using Fresnel lens can achieve reduced weight and thinning of the alignment assisting device for eye drops.一種眼藥水輔助對準器,配合一眼藥水瓶使用,該眼藥水瓶具有一瓶嘴。眼藥水輔助對準器包含一外框、一反射鏡、一菲涅爾透鏡及一固定件。反射鏡嵌設於外框,包括一透明基板及一設置於透明基板的反射層,且透明基板形成一供瓶嘴穿設的第一通孔。菲涅爾透鏡嵌設於外框中對應反射鏡的位置,並形成一對應第一通孔位置以供瓶嘴穿設的第二通孔。固定件設置於反射鏡,用以固定眼藥水瓶。藉由菲涅爾透鏡與反射鏡的配合,使用者點眼藥水時能觀察到放大的眼部影像,而提升精確度及便利性。此外,使用菲涅爾透鏡可達成眼藥水輔助對準器的輕薄化。1‧‧‧眼藥水輔助對準器2‧‧‧外框3‧‧‧反射鏡31‧‧‧透明基板311‧‧‧第一通孔32‧‧‧反射層4‧‧‧菲涅爾透鏡41‧‧‧第二通孔5‧‧‧固定件
