Eye Color Changer is a free Android app developed by Opeslink that allows you to change the color of your eyes' lens. The app uses a unique blending technique that creates a natural-looking effect on the eyes, regardless of whether they are dark or light. You can now try out different colors and effects on your own photos, including standard color contacts, exotic contacts, scary eye effects, alien/animal eyes, and more.

One of the best things about this app is that it's easy to use. Simply select a photo from your camera gallery and choose from the many real and natural eye color lenses available. You can also change the size of your eyes to make them look bigger and more beautiful. Additionally, the app has a mode that allows you to place different lenses on each eye for a more unique and personalized effect. Once you're done, you can share your new look with your friends and family over social media.
