Cinematographer
Sklerallinsen verändern die Augen meiner Darsteller komplett. In Nahaufnahmen muss ich darauf achten, dass die Linsen-Kanten nicht sichtbar werden – Licht und Winkel sind kritisch.
Large-diameter custom contact lenses that cover the entire visible eye including the sclera (white), used in film to create dramatic character transformations – from demonic appearances to alien eyes, fitted by specialized ocularists and typically worn for limited periods due to comfort constraints.
What are Scleral Lenses?

From the crafts
Perspectives
Director
Sklerallinsen transformieren menschliche Augen in etwas Unmenschliches. Der Effekt ist unmittelbar und überzeugend – keine Postproduktion kann diesen praktischen Look ersetzen.
Producer
Sklerallinsen erfordern spezialisierte Anpassung und medizinische Aufsicht. Die Kosten sind erheblich, aber der visuelle Impact rechtfertigt die Investition bei Charakteren, die auf diesen Look angewiesen sind.
