See what they see
Six common conditions on three everyday scenes. Drag the lens to see what a prescription or an early diagnosis gives back.
Short-sighted
Myopia. Near is clear, far is soft: road signs, the board at school, faces across a room.
What helps: Glasses or contact lenses; myopia control for children.
An illustration to show why tests matter. It cannot diagnose anything.
The conditions, in plain words
- Short-sighted
- Myopia. Near is clear, far is soft: road signs, the board at school, faces across a room. Glasses or contact lenses; myopia control for children. How we test
- Long-sighted
- Hyperopia. Close work blurs and tires you, often with headaches after reading. Glasses or contact lenses. How we test
- Astigmatism
- The eye focuses one direction better than the other. Edges smear and lights streak. A cylinder in your prescription, glasses or toric contact lenses. How we test
- Presbyopia
- From about 40 the eye's lens stiffens and near focus fades. Arms get "too short". Readers, bifocals or multifocal lenses. How we test
- Cataract
- The eye's lens clouds over: hazy, yellowed, glare around lights. Found in an eye test; referral when it affects your life. How we test
- Glaucoma
- Side vision is lost first, slowly and without pain. Screening finds it early; treatment slows it. How we test
Only a test can tell.
