Activity 10.1 — Accommodation of the Eye
NCERT Activity 10.1: Observe how the eye lens changes shape to focus on near and distant objects — the power of accommodation.
How To Perform
1
Look at a Distant Object
See how ciliary muscles relax and the lens becomes thin for far vision.
2
Look at a Near Object
Watch ciliary muscles contract and the lens thicken for near vision.
3
Compare Both States
Compare the thin vs. thick lens and understand focal length changes.
4
Accommodation in Action
Toggle between near and distant focus interactively.
5
Classify the Response
Explain how accommodation works in the human eye.
⚠️ Safety Notes
- •Do not look directly at the sun or bright light sources — it can damage the retina.
- •Take regular breaks when reading or using screens to avoid eye strain.
- •If you experience difficulty focusing, consult an eye specialist.
