Kernrechtsfrage
Whether the claimant is entitled to a disability pension.
Extrahierter Entscheid
No pension entitlement was shown because no legally relevant impairment of health and no pensionable loss of earning capacity were established.
Extrahierte Begründung
The cantonal findings were binding and showed no invalidity-relevant health damage; the alleged visual episodes no longer occurred and thus did not support a pensionable incapacity.
