Direct electronic/nerve interface at TL–9 opens the way for a wide variety of cybernetic enhancements to eyesight. Early cybernetic eyes are single-function eyes and are easily recognizable as mechanical implants. The initial introduction of the technology always recognizable as mechanical implants. At higher tech levels the eyes look more like natural, unaltered eyes.
In all cases, the cyber eye includes basic visible light vision. For Sophonts with different visual ranges the basic cyber eye will cover their normal visual range.
Several options are available for cyber eyes. The versions that look like natural, unaltered eyes are two TLs higher than the base models shown. Combining options requires eyes of one or two TLs higher than the base models.
Telescopic: Telescopic vision allows magnification similar to telescopic binoculars, with zoom controlled by eyeball pressure (which is manipulated by squinting). TL–10, Cr 10,000
Active Infrared: A beam of infrared light (NIF visual bands) is projected either from forehead-mounted lights (in the hard version) or through the eye itself (in realistic version). Active infrared is a useful sensor at night, but will not penetrate smoke, dense fog, blowing sand, etc. It has a range of 60 meters. TL–10, Cr30,000
Eyeball Display: This allows projection of information in readable form in the user's field of vision, much like the heads-up display of a fighter aircraft. It is particularly useful if a computer implant is used, but can is also useful with chronometer or inertial navigation implants. TL–11, Cr10,000
Passive Infrared: The eye is extremely sensitive to infrared radiation (ANI visual bands) and can "see" heat. Most living creatures and machines have distinct heat signatures. This has a range of around 100 meters. TL–11, Cr50,000
Light Amplifiers: Eyes use light-amplification techniques to allow normal vision in low light conditions (primarily nighttime using starlight, hence the name). Smoke, blown sand, and any sort of atmospheric conditions will interfere with eyes. They have a short range of 100 meters. TL–11, Cr100,000
Rangefinder: This option may only be installed if the user also has an eyeball display. The rangefinder projects a low-energy infrared laser beam and determines range from the reflection. It is accurate to within 1% of range out to 5 kilometers. TL–11, Cr20,000
Color Enhancement: originally developed to aid color-blind patients, it resolves detail at long distances and detects camouflage. Color hue and intensity is adjusted by increasing or decreasing eyeball pressure. This can be accomplished by squinting. TL–12, Cr5,000
Recorder: This option allows recording a video and play it back later. If connected to a implanted communicator or computer, the recording time is limited only by computer capacity. On their own the recorder can record up to one hour of video. The recorded video can be transferred by means of a viewer that fits over the eye. TL–12, Cr50,000
Imaging Radar: The eye contains a millimeter wave radar transmitter and processor unit with fine enough resolution for image formation. Imaging radar has a range of 300 meters and is not degraded by any atmospheric effects. TL–13, Cr2,000,000
Holo-recorder: This option allows recording a 3D holographic images and play it back at a later time. If connected to a implanted communicator or computer, the recording time is limited only by computer capacity. On their own the recorder can record up to one hour of video. The recorded video can be transferred by means of a viewer that fits over the eye. TL–14, Cr1,000,000
Thermal Viewer: Also called HRT (for high resolution thermal), is an advanced form of passive infrared (ANI visual bands) with a range of 400 meters. HRT can see clearly through most forms of smoke, but is affected by rain or snow. TL–14, Cr100,000
Image Intensifier: Image intensification not only magnifies but also sharpens focus and contrast, making visual recognition easier. Image intensification also adds the light-amplifying ability. They have a range of 250 meters. TL–14, Cr100,000
Wide Spectrum Visual: This eye combines magnification and image enhancement with sensitivity to light across a broad spectrum, from ultraviolet through infrared (USPBGRCAN visual bands). As such, it combines most of the advantages of earlier sensor eyes in a single package. This has a range of 400 meters. TL–15, Cr500,000
