Dva Oka (Two Eyes) is a rather strange karst spring, which consists of two subsequent almost circular lakes, which actually look like two eyes from above. They are located in the Najizdašniji izvor rijeke Vrljike (Special Reserve Vrljika River Spring). The first part of the river with its blue water and the endemic trouts is a geotope and nature protection area, there are dams in the river, and a nice park along the river. Endemic animal species which live in Vrljica river include the soft-lipped trout (Salmothymus obtusirostris), the white-legged crayfish (Austropotamobius pallipes) and the Imotski gaovica (Dhelminichthys Adspersus). An area of 50 ha from the source was declared a protected ichthyological reserve.

The Vrljica river flows through a fertile plain which is called Imotski Krajina (Imotski Field). Imotski was named after the old Croatian parish of Imota (Emotha), the name is of Illyrian origin. It has some fame in Croatia for its soils, especially as most of the country is bare karst. The town Imotski is said to have 11 natural and one artificial lake.

The Vrljica river has six springs, it seems a karst aquifer close to the surface found numerous cracks where it could flow out. The Dva Oka are the first spring. Along the course of the river are more springs, Opačac (Bad Guy), Izvor Krčevac (Krčevac Spring) are the most interesting. There are more places where the karst aquifer is visible. The most spectacular are nearby Crveno jezero and Modro jezero, two dolines which are deep enough to reach the water level. All those geotopes are part of the Biokovo-Imotska jezera Geopark.
