Strictly speaking, she is affected, but you may want to decide that she is not affected.
75-76 They glow in the next minute in a radius of 30 feet with bright light.
Any creature that completes its turn within 5 feet of you will be blinded until
the end of his next round.
She is a creature within 5 feet of herself (0 even, she is the starting point) and she is blinded. It is not exempt from the effects, unless otherwise stated in the description. If someone throws a fireball at them, they are affected.
For all purposes it is formulated as a Bullet (PHB 204):
You select the point of origin of a sphere and the sphere extends outward
from this point. The size of the sphere is expressed as a radius in feet
that extends from the point. The origin point of a sphere is included in
Effective area of the sphere.
The point of origin of a sphere is within the sphere's sphere of influence, but if you compare it to other reels on the Wild Magic Surge table (PHB 104):
95-96. You and all creatures within 30 feet gain in vulnerability
for the next minute to piercing damage.
You will find that the wording is chaotic. It makes it terribly clear that this may not be the intended formulation. I would therefore recommend that you rule this rule as if it were freed, and extend that rule to rid it of the 69-70 invisibility effect. Alternatively and strictly RAW follow the effects. For both throws, the latter would mean that she would be affected – she becomes blind on a 75-76 and invisible on a 69-70.
Continue to compare how the invisibility effects are formulated (and be dismayed by their wording):
69-70 Any creature within 30 feet of you will be invisible to you
next minute. Invisibility ends when a creature attacks or
Acts a spell.
89-90 You become invisible for the next minute. Meanwhile
Time, other creatures can not hear you. The invisibility ends when you
attack or cast a spell.
