Kernrechtsfrage
Whether the insured showed a legally relevant deterioration in health or earning capacity since the last final pension refusal.
Extrahierter Entscheid
No legally relevant worsening was established; the prior finding of full work capacity in light work largely remained valid, apart from a visual limitation.
Extrahierte Begründung
The Federal Court accepted the cantonal court's factual assessment. The new eye condition only excluded work with high visual demands, while the other diagnosed conditions did not affect capacity to work. The record therefore did not justify further medical investigations.
