Go to the top of the SPY building and talk to the spy there. Decode his message, and you have your answer.
you need to fail the eye exam
go into spyglass eyeware. ask for an eye exam. then click the E's pointing the opposite direction. if you do it right, he will meet you upstairs. (he will unlock the door.)
You take an eye exam and tell everything backwards. Example (not quite but you get the idea): When he does: E you do 3 3 you do E W you do M M you do W
You can't get rid of them. The only way to get past them is to go see Dr. Spyglass. Then ask for an eye exam,when you do you must answer the letters in the opposite direction. When you are done with the exam, he will ask you to meet him upstairs. You must go outside and open the door that is now unlocked. Talk to Dr. Spyglass and he will give you a chameleon suit. Wear it and you will be able to sneak past the B.A.D. agents. I hoped I answered your question! :)
Go to the right and you will see a place called " Spyglass Eyewear" enter and go to the left talk to the doctor and say "I would like an eye exam." In the eye test, the letters are random and always change between tries. The key is to pick the mirror-image (opposite) of the letter he points to. For example, W instead of M, or backward E (3) instead of E. Getting them all wrong in that way tells Dr. Spyglass that you are a friendly spy.
You go passed the hair club going left then you see a man hiding in a trash can but get the camoflauge suit from Dr. Spyglass though. To get the camo suit ask for an eye exam then point to the opposite letter he points to.
First, you must pass Dr. Spyglass's test. Then, you can exit out of Dr. Spyglass's store. Go a little to the left, and then climb up the ladder. You will see a door. Enter it and you will be in the Lab!
You have to go to doctor spyglass and ask to get an eye exam then you have to click the oppisit of the letter then u have to meet him upstairs. He will give it to you
When Dr. Spyglass gives you an eye exam, he points to letters on the chart. Each time, pick the symbol that points the OPPOSITE way (backward E instead of E, M instead of W) so that you get all of the answers wrong. This shows him that you are a friendly spy.
When Doctor Spyglass leaves, exit the shop and go to the outside door on the second floor, which is now open.
Dr. Sacco charges $50 for an eye exam but waives the fee if you also buy glasses. Nice guy.
You do Dr. spyglasses' eye test and he tells you to meet him up stairs. climb up the ladder and walk in the door. talk to Dr. spyglass and he gives you the chameleon suit.
