The eye drops puzzle requires you to examine the bottle cap and use the tweezers from your inventory

In Riddle Transfer 2, the eye drops are a locked item that you cannot use until you solve the mechanism holding them closed. The puzzle involves finding and using the tweezers on the bottle's cap to release a catch. You'll find the tweezers elsewhere in the game world — they're a separate inventory item you need to collect first. Once you have both the tweezers and the eye drops in your possession, you can interact with the eye drops and select the tweezers as the tool to open them.

The game won't let you use the eye drops on anything until this step is complete. This is a deliberate gate: the puzzle teaches you that some items require specific tools, and that you need to explore the environment to find those tools before you can progress.

Key Takeaways

  • The tweezers are a separate item you must find and add to your inventory before you can open the eye drops.
  • Once you have the tweezers, interact with the eye drops in your inventory and choose the tweezers as the action.
  • The eye drops won't function in the game until you've completed this puzzle — they remain locked until then.
  • If you're stuck, retrace your steps through areas you've already visited, as the tweezers are often in a location you've passed through.

Where to find the tweezers

The tweezers are typically located in a room or area you visit early in the game. They're usually sitting on a surface or in a container that you can examine. The exact location depends on which version of Riddle Transfer 2 you're playing and how far you've progressed, but they're always findable without completing other major puzzles first.

Check desks, shelves, bathroom areas, and any room with medical or personal care items. The tweezers fit thematically with the eye drops, so the game often places them near each other or in related spaces. If you've already picked up the tweezers without realizing what they were for, check your inventory — you may already have the tool you need.

How to use the tweezers on the eye drops

Once you have both items in your inventory, open your inventory screen and select the eye drops. The game will show you available actions or tools you can use on that item. Select the tweezers from the list. Your character will use the tweezers to manipulate the cap mechanism, and the eye drops will unlock.

After this interaction, the eye drops become usable in the game world. You can now use them on other objects or characters as the puzzle or story requires. The game will typically give you a clear indication that the action was successful — the eye drops' appearance may change slightly, or you'll receive a message confirming they're now open.

What to do if you can't find the tweezers

If you've searched the obvious locations and haven't found the tweezers, backtrack through areas you've already explored. Riddle Transfer 2 sometimes requires you to revisit spaces after you've solved other puzzles or progressed the story. An item you couldn't pick up before might become available after a certain event.

Check your inventory carefully — sometimes players pick up items without paying close attention and forget they have them. If the tweezers truly aren't in your inventory and you've explored thoroughly, you may need to restart from a recent save point or check a walkthrough for the specific version you're playing, as item locations can vary between releases or updates.

Why the game locks the eye drops

Riddle Transfer 2 uses locked items as a core puzzle mechanic. By requiring you to find a specific tool before you can use an item, the game teaches you to think about object interactions and to explore systematically. This design also prevents you from using items out of sequence, which could break the puzzle logic or story progression.

The eye drops puzzle is relatively straightforward compared to other locks in the game, but it establishes the pattern: examine your surroundings, collect tools, and match tools to the items that need them. Understanding this mechanic early makes later, more complex puzzles easier to approach.

Frequently Asked Questions

Can I open the eye drops without the tweezers?

No. The game requires you to use the tweezers specifically. There is no alternative method or workaround. You must find the tweezers and use them on the eye drops before the item will unlock.

What if I lost or dropped the tweezers?

If you dropped the tweezers, return to the location where you last used or saw them. Items you drop in Riddle Transfer 2 typically stay where you left them. If you can't find them, check your recent save files and reload from before you dropped them.

Do I need the eye drops to beat the game?

That depends on which puzzle path you're following. Some solutions in Riddle Transfer 2 require the eye drops, while others don't. If you're stuck on a puzzle, the eye drops might be one solution, but not necessarily the only one.

Can I use the tweezers on other items?

Possibly. Riddle Transfer 2 sometimes allows tools to work on multiple items. Try using the tweezers on other locked or sealed objects you encounter. The game will tell you if the tweezers won't work on something.
