Face DR

Face DR may refer Damage Resistance bought with the Partial limitation of Face only.

*Face DR does include eyes
**(when hit at a -9 penalty).
*However, normally, people target Slits, which are basically Chinks in Armor on the eyes (-10).
**Helmets which include the eye hit location specifically are not subject to the Chinks vulnerability over the eyes, and protect at the listed Eye DR instead.
This FAQ is likely intended for equipment which raises the question how it might work as an advantage, since DR is not meant to protect eyes w/o Force Field.
The pricing of Nictitating Membrane appears to imply more than a -70% discount (-90% based on -9 x 10% +20%) value since it's a leveled perk, which requires -80% for DR from 5/level. NM also has the additional benefit of Resistant to Eye Injury type effects of Protected Vision.
One possible approach is to require Force Field, but also apply the -90% "eyes only" cost to the enhancement too ala Limited Enhancements
That makes sense as otherwise Force Field (non-limited) adds "all equipment worn everywhere" to "whatever of my body is protected". Compare:
*DR (Force Field +20% One Hand Only -80%) = "my hand and any equipment I'm wearing".
*DR (One Hand Force Field +4% One Hand Only -80%) = "my hand and any equipment I'm wearing on my hand"
In the case of the eye, "protects the eye" benefit of forcefield could be seen as replacing "equipment worn on my eyes", so it should not protect glasses, for that get "Face Forcefield +10%" instead.
If not taking this LE approach (assume that "X only" not only limits the body parts protected but also which worn equipment is protected) it becomes less flexible.
*to get force fields protecting ONLY worn equipment, something like -100% "doesn't protect me at all" (see Reflection for example) but then taking +20% probably could make sense.
**in this case your equipment would suffer less damage from getting penetrated by attacks, but it wouldn't help them provide more cover DR for you
***this does have the advantage of helping them provide DR for longer periods of time based on Damage to Armor rules in Low-Tech.
*this might also be done to make Affects Others DR which never helps the user

If -100% is too steep this, "not me" for AE DR could be done via Accessibility. Here is how:
*One Person Only is a -80% Accessibility but that could just be due to the -80 cutoff so you need to go a step higher
*PU8p5 "one in one million" is -60% which ties it with B46 Limited: Occasional
**Bane for Occasional is -10%
***ergo: "Accessibility: everyone but one in a million" should be -10%.
****you can then specify yourself as one of those. This has the benefit in 10mil pop of there being 9 others instead of 10 others who you can't protect.
This inversion might be wrong though because PU8p4 requires dropping from 94% to 93% to go from -0% to -5%. Not affecting 7% of people is way more than 1 in a million! So apparently you can't just use the Limited/Bane rarity relationship to invert things.
Probably how you could tailor this is:
Accessible (97% targets) -5%
cancel w/ "not accessibility +5% (inverse limitation per restructurable magery) similar to EOL but it's better to price i tout
You need to save at least 20% to matter, so that's working 56% of the time at most...
56% of 3% is 1.68%... which you would add to the usual 97
so Accessibility -1% should work 98.68% of the time.

Reducing 20 to 4 making the net modifier -86%, enough to reduce it to a perk. The 6% difference might be what pays for the resistant/protected V. 
Skull has been used as a -70% limitation implying Face is always -50% even though this gets muddled by the change in penalties to hit these locations based on position of enemy.
*similarly a "standing posture" is probably assumed: there's no change in these penalties introduced by the new rules which make it easier to hit certain locations based on posture of attacker/target
