Solid Eye (technology)

The Solid Eye is a technology made into the form of an eyepatch and used by Solid Snake in Metal Gear Solid 4: Guns of the Patriots.

Name
The name of the Solid Eye was taken directly from the Solid Eye peripheral used with Metal Gear Ac!d 2. Apparently, Hideo Kojima took the name from the peripheral for use with the eyepatch without even asking the producer of MGA2.

Functionality in GotP
Not much is known about the use of the Solid Eye, but it is expected to have functions like to night vision and thermal vision (which have both been featured in previous games).

Appearance
The Eye appears similar to an eyepatch, with the text "SOLID EYE" and a serial number appearing on the front and a small camera lens over the text. It should be noted that the Solid Eye combined with Snake's rapid age make Snake look similar to his "father", Big Boss, in his final years, though Big Boss wore his eyepatch on his right eye whereas Solid Snake wears the Solid Eye on his left.
