Yes it can - Caffeine is a stimulant and causes a release of adrenaline.
Adrenaline is the hormone which prepares us for 'fight or flight' in stressful situations and it has a number of effects on the body. One of these effects is dilated pupils (if you are going to fight or run away from danger, you will need to be able to see as well as possible!)

Which dilates the pupils?
Pupils dilate when there's not enough light in the room or area you're in. They dilate to let in as much light as possible so you can see as well as you can in the dark. When outside and it's bright, your pupils get smaller because there is too much light. ~ ~Imadork881 changed to Sleenky ^.^

Why are both eyes dialated with NO drugs?
The part of the eye that dilates is known as the pupil. It sometimes dilates when you look at someone that you are physically attracted to. This happens because of a chemical reaction in your brain. Pupils also dilate according to how much light is present to allow better vision. Pupils are dilated when there is little light available. You can test this out by looking in a mirror where there is a lot of light (your pupils should be very small because allowing too much light in damages the eyes). Then look into a mirror where there is less light and your pupils will have dilated. During a concussion, a person may also have dilated pupils. I'm not sure why, but probably as a result due to the force of impact sustained by the head.
