Understanding Your Vision: The Importance of Visual Acuity

What Is Visual Acuity?

Visual acuity refers to the sharpness or clarity of your vision. It measures how well your eyes can see details at a specific distance, usually tested using an eye chart.

Results are often expressed as a fraction, such as 20/20. This means you can see at 20 feet what a person with normal vision can also see at 20 feet.

Why Visual Acuity Matters

Visual acuity is essential for many daily activities and safety-related tasks. Reduced clarity can affect performance at work, school, and on the road.

• Helps detect vision changes early
• Guides accurate eyewear prescriptions
• Improves comfort and reduces eye strain
• Supports safe driving and screen use

Signs Your Visual Acuity May Be Changing

Vision can change gradually, making it easy to overlook early signs. Common symptoms include:

• Blurry or fuzzy vision at distance or near
• Squinting to see clearly
• Frequent headaches or eye fatigue
• Difficulty reading signs or screens

How Eyewear Improves Visual Acuity

Prescription glasses and sunglasses are designed to correct refractive errors such as nearsightedness, farsightedness, and astigmatism—allowing light to focus properly on the retina for clearer vision.
