Physical Illusions: Physical illusion spells create actual
images or alter physical properties, such as light or sound.
Physical illusions are effective against technological systems,
assuming the caster achieves enough hits to meet the
Object Resistance threshold (see p. 174). They are resisted by
Intuition + Counterspelling (if any); non-living devices do
not get a resistance test. The observer must generate more hits
than the spellcaster to determine that the illusion is not real.
If the spell is not completely resisted, the character is fully affected
by the illusion.

Invisibility (Realistic, Single-Sense)
Type: M • Range: LOS • Duration: S • (F ÷ 2)
Improved Invisibility (Realistic, Single-Sense)
Type: P • Range: LOS • Duration: S • DV: (F ÷ 2) + 1
This spell makes the subject more difficult to detect by normal
visual senses (including low-light, thermographic, and other
senses that rely on the visual spectrum). The subject is completely
tangible and detectable by the other senses (hearing, smell, touch,
etc.). Her aura is still visible to astral perception.
Anyone who might perceive the subject must first successfully
resist the spell. Simply make one Spellcasting Test and use the hits
scored as the threshold for anyone that resists at a later point. Even
if the spell is resisted, the subject might remain unnoticed if she
wins a Shadowing or Infiltration Test. An invisible character may
still be detected by non-visual means, such as hearing or smell.
Attacks against invisible targets suffer the Target Hidden
modifier (p. 141) if the attacker is unable to see or otherwise
sense the subject of the spell.
Invisibility affects the minds of viewers. Improved invisibility
creates an actual warping of light around the subject that affects
technological sensors as well.

Then BBB says


Does this mean that Improved Invisiblity (a physical spell) doesn't need to make the object resistance threshold?
So if I have a character with Cyber eyes... do they need to overcome the object resistance test to be invisible to me or does the text as written here mean that they don't?

you still have to overcome OR and people still get a resistance test.

although cybereyes only have OR if they're not installed... when installed, the person who has the cybereyes makes a resistance check, and OR doesn't factor in at all.

try not to think about that too hard... your brain may explode.

Oddly, given that:
Imp. Invis involves a "physical warping of light"...
And it no longer has grades of succes - you're either invisible to something or not...
And the fact that it does make you absolutely invisible, in that all light passes through you...

Means that IF you beat a high enough object resistance, you should technically be immune to all laser weapons.

Has anyone had this come up in their games?

Yeah, but I chose to ignore that line of the description. I mean, the function of the spell is to make you inivisble, and it's obvious it does that. I figure that if the spell also made you blind, they'd probably have noted that.

This is precisely why I try to steer away from the "easy" science-y answers for magic. Because sometimes you end up blind.

I use this because invisibility as a spell is almost useless with all the ways one can counter it per the RAW.

are you emo samurai's alternate identity or something?

As for Improved Invisibility, I've considered banning it several times, just because it can derail a game in to a rules argument very quickly. The Pseudoscientific description about bending light has alway bugged me, mostly because ways to actually bend light almost always involve disgustingly large gravitational fields, though if applied this could be funny.

"You need 1 x 10^50th more, the invisibility increased your mass by 50 orders of magnitude to bend the light, oh and the floor below you is starting to give way"

Not to be silly, but if you're going to discuss the scientific point of view, at the point where your mass starts bending light, it's the Earth moving towards you, not the other way around
