Visual Acuity
This is how clearly and sharply you can see details at a specific distance. It measures the eye’s ability to distinguish shapes, letters, and objects with precision.
Think of it like the resolution of a camera—higher visual acuity means a clearer, sharper image, while lower acuity makes things blurry or difficult to distinguish.

Why is Visual Acuity Important?
Visual acuity is important because it affects how clearly we see the world around us. Whether it’s reading a book, recognizing faces, or driving a car, sharp vision is essential for daily life, learning, and safety.
💡 Think of it like this: If your eyes can't see objects clearly then it's hard to make out the shapes of words on a page or see if it's your friend standing in front of you or a tree!

Types of Visual Acuity
Distance Visual Acuity – How well you see far away using a Snellen chart.
Near Visual Acuity – Uses a small reading chart to measure reading clarity up close.
Pinhole Test – Helps determine if blurry vision is caused by a focusing problem or another issue.

What Happens When Visual Acuity is Weak?
You can identify people by:
🔹Children who squint or complain about blurry words
🔹 People with frequent headaches or eye strain
🔹 Those recovering from a concussion, stroke, or brain injury

How is Visual Acuity tested?
The most common way to measure visual acuity is through the Snellen Eye Chart Test (you know, the one with big letters at the top and smaller ones below!). But we use a machine called an Autorefractor which gives your prescription in 10 seconds!
✅ 20/20 vision – You can see clearly at 20 feet what most people can see at 20 feet (normal vision).
✅ 20/40 vision – You need to be 20 feet away to see what someone with normal vision can see at 40 feet.
✅ 20/200 vision – You are considered legally blind if your best corrected vision is this level or worse.
