Educational information, not veterinary advice or a home vision test. Do not darken a room, add obstacles or shine light into the eyes. If sight changes or you are worried, seek veterinary advice as soon as possible; do not wait for notes or an app reply.
Build a light-and-layout note from an existing scene
Use only an existing scene. No new darkness, obstacle, flash or eye examination. Entries are not saved or sent; reload clears them.
Use an event that already happened
Record ordinary facts you already know: the room, available light sources and the movement you noticed. This is a writing aid, not a request to recreate the scene. No new darkness, obstacles, flash or directed light is needed.
Leave the view from the eyes unknown
You can know that a lamp was on without knowing exactly what the cat could see. The output preserves your text; it does not translate the scene into feline vision, assign a score or make a safe-light recommendation.
Temporary means not saved or sent
Fields remain in this page only. Reset clears the output, and reloading clears entries. The tool neither stores information nor copies it to a clipboard or sends it to a professional. Use your own records if you want to keep a note.
A concern bypasses the form
If you are worried about a sight change, seek veterinary advice as soon as possible. A blank note is acceptable and does not prevent you contacting the team. The form is not a referral, emergency service or substitute for assessment.
