Eyes
Eyes have been a major theme on LOST from the very first scene of the Pilot episode which began with a close up of Jack opening his eye. Several other episodes have also begun with eyes.

There have been many, many references to eyes.

Including Alex's statement in S3E9 that the Others' form of justice is an

"Eye for an Eye" S3E9 Alex to Jack

And there has been some very obvious manipulation going on with eye color.


Why all the references to eyes? Perhaps we are meant to not only notice them, but to pay attention to them. Maybe the name of the island is actually "The Eyeland" and maybe Locke was being literal in S1E5 when he said, "I looked into the Eye of this Eyeland, and what I saw was beautiful"?

The Blinking Eyes
Watch the background of the scene very carefully in S3E8 as Desmond throws his tie to the ground. The signs on the news stand change from reading News Agent to News. The fonts also change. But there is also a poster on the kiosk behind him.

And the woman in the poster blinks! Her eyes are open and then they are closed. It happens very quickly and can be difficult to spot.

Eyes and Eye Color
The release of the Season 3 Promo Poster in Fall 2006 brought up the subject of eyes and eye color again. It is obvious that all of the characters on the poster have had the color of their eyes altered. Jack's are the most obvious since they are two different colors. But all of them have been changed in the photos. For example, Sawyer's eyes should be blue and Kate's should be green.

There is a second promo poster that was been released for the Season 3 episodes that began on February 7, 2007. Juliet, Nikki and Paolo have been added to the second version of the poster. Eko is now missing.

Once again all of their eye colors have been altered. It is interesting to note that while Jack's eyes are still not the right color, at least both of them are the same color in this version of the poster. But look at Locke's eyes, in this second poster, they are now two different colors.

Why Change Their Eye Color?
I have received much criticism for my opinion that there is a good deal of deliberate manipulation going on with eye color on LOST. I agree that it is often difficult to discern what is actually happening with their eye color.

My response is always the same. Go back and watch S1E2 when Locke is introducing Walt to backgammon, he holds up the backgammon pieces and says " 2 players. 2 sides. One is light. One is dark. "

Look at Locke's eyes. They are brown, not blue. No doubt about it. BROWN. This can also be seen in the "Previously On LOST" segment of S1E5, it occurs at 30 seconds.

There is further proof that it is not just in my imagination, because there is a great quote from Terry O' Quinn in a thread on the Fuselage about having to wear colored contacts in some episodes of LOST. He refers to wearing the black and white contacts for S1E10 and he also refers to having worn blue-green colored contacts for another episode.

So, the question is not if their eye color is being manipulated, but why is it being done?

And the answer is not simply color correcting scenes, as might be indicated on the S2 DVD in the discussion by Randy Coonfield where he talks about color correcting a scene in S2E12 and the effect it had on Charlie's eyes which became bluer. That type of color correcting to a scene could not result in a character having two completely different colored eyes.

After going back and looking at some of the episodes, I found a few interesting things about the characters' eyes that seem to have slipped by the majority of the audience.

As a word of caution, pull out your DVD's. The examples below are much easier to see in the episodes on the DVD's than they are in any screen captures I have seen. In fact, it actually helps to view the episodes on a large screen HDTV to actually see the color changes.

And, as a final note, on the S2 DVD when referring to the scene in S2E12 where Charlie has his dream, it is noted that the drug plane was only visible to people who saw the episode in HDTV or who see it on the DVD. So it is entirely possible that other things might also be more clearly indicated on the DVD's. Which would be a big reason to buy the DVD's instead of downloading episodes over the internet. It amounts to being a very clever way to drive DVD sales.

All Characters Have Had Eye Color Changes
Each one of the main characters have had their eyes appear to be a slightly different color than usual in numerous scenes. Their eyes have also been black in a number of instances. This is more than just lighting or shifts in eye positions. There are also many times when just one of their eyes is deliberately in shadow. A prime example of this can be found toward the end of S1E11 where Jack is in a scene where he is talking to Charlie about what he remembers.

As Season 4 progressed and most notably in Season 5, there seems to have been a decided shift from having a character go through eye color changes as often as had been seen in previous Seasons. In these later episodes, it is much more prevalent to see one eye in light and one eye in shadow as a character is going through a role change.

But it is more than just one contact slipping as many people have written about in various chat rooms. If you watch it very carefully, both eyes are affected.

Eye Color and the LOST Action Figures
An eagle-eyed fan spotted something interesting about the Kate LOST Action Figure. It seems that while most of the Kate Action Figures available do have the correct green colored eyes for Kate, there are some figures of Kate out there that have brown eyes. See Official Games and Toys for pictures of the Action Figures, both boxed and un-boxed.

So, What Does It All Mean?
I believe that the changes in their eye color are associated with a change in their game roles. And that the changes occur when they change from a 'good' role to a 'bad' role, or vice versa, from a 'bad' role to a 'good' role.

There are several examples that illustrate this:
• S1E13 The Detective's eyes change when he changes from being the Sheriff (arresting Sawyer)to being the Daddy (talking about his kids)
• S2E10 Eko's eyes change when he goes from being the Rock God (drug dealer) to being the Man of Faith (papers identifying him as a priest)
• S2E20 Libby's eyes change when she changes from being the Shrink (helping Hurley) to being the Con Man (when Hurley says he is trying to remember where he knows her from)
