What is 20/70 Vision?
When someone has 20/70 vision, it means that they can see objects clearly at a distance of 20 feet that someone with normal vision can see at 70 feet. This measurement is part of the Snellen chart system, which is widely used in vision testing. Essentially, 20/70 vision indicates a significant level of visual impairment, but it does not necessarily mean blindness.
Understanding Visual Acuity
Visual acuity is measured based on how well a person can see objects at a specific distance. The Snellen chart, which features rows of letters that decrease in size, is the standard tool used to assess visual acuity. A person with 20/20 vision can see the smallest letters on the chart clearly, while someone with 20/70 vision struggles to see the same letters without assistance.
It's important to note that 20/70 vision can affect both near and distance vision, depending on the underlying cause. Understanding the specifics of your vision measurement is the first step toward addressing any issues.
The Vision Testing Process
Diagnosing 20/70 vision involves a comprehensive eye examination conducted by an optometrist or ophthalmologist. The testing process typically includes several components:
- Visual Acuity Test: This measures how well you can see at various distances using the Snellen chart.
- Refraction Test: Determines the exact prescription needed to correct your vision.
- Eye Health Examination: Checks for any underlying conditions that may contribute to vision problems.
Regular eye exams are essential for maintaining optimal vision health, especially if you notice any changes in your sight.

Importance of Early Detection
Early detection of vision problems is critical for effective treatment. Many conditions that lead to 20/70 vision, such as cataracts or macular degeneration, can be managed or treated if caught early. Regular check-ups with an eye care professional can help identify issues before they become severe.
Causes of 20/70 Vision
Several factors can contribute to the development of 20/70 vision. These include:
- Refractive Errors: Such as nearsightedness, farsightedness, or astigmatism.
- Cataracts: Clouding of the eye's lens that affects vision clarity.
- Macular Degeneration: A condition that affects the central part of the retina, leading to blurred vision.
- Diabetic Retinopathy: Damage to the blood vessels in the retina caused by diabetes.
Each of these conditions requires a different approach to treatment, so accurate diagnosis is crucial.
Preventable Causes
Some causes of 20/70 vision, such as refractive errors, can be corrected with glasses or contact lenses. Others, like cataracts, may require surgery. Understanding the root cause of your vision problem is the first step toward finding the right solution.
