EyeSimulate

See inside the eye and through it at the same time. Choose an eye condition: the 3D eye model shows what changes inside the eye, and the vision preview shows how the world can look to someone with it, using photos from around Brunei or your own phone camera.

How to use

• Choose a condition. The 3D eye and the vision preview change together, and a short note explains how one leads to the other.
• Turn the 3D eye: drag to rotate, pinch or scroll to zoom. Use Side, Front and Inside to jump to a view, or tap Move the eye to watch floaters and blood swirl and settle, just as they do in a real eye.
• Move the slider from mild to severe. Hold Compare to see normal vision, or switch between Side by side and Big view.
• Pick a scene, or tap Use my camera to see the world around you through the simulation. Works best on a phone.

Good to know

• These are simplified models and simulations to help you understand. Real eyes, and what each person sees, differ from person to person. Some changes are made bigger in the model so they are easier to see.
• Many eye diseases, such as glaucoma and diabetic retinopathy, have no symptoms at first. Regular eye checks find them early.
• If your vision changes, get your eyes checked. Sudden changes are an emergency: a shadow or curtain over your vision, a shower of new floaters or flashes, sudden blurring, or a painful red eye after eye surgery. Go to the Emergency Department straight away.
