What Does 6/60, 3/60 or 1/60 Vision Mean?

If you've seen a number like 6/60 or 3/60 written on your eye test results and wondered what it actually means, you're not alone — this is one of the most common questions patients ask after a vision test.

How to read the fraction

These numbers describe visual acuity — how clearly you can see — measured using a standard eye chart (a Snellen chart) at a set distance, usually 6 metres. The fraction works like this:

• The top number (6) is the distance, in metres, at which you're standing from the chart during the test.
• The bottom number is the distance at which a person with normal vision could read that same line clearly.

So 6/60 means: standing 6 metres away, you can only read letters that someone with normal vision could read from 60 metres away. The bigger the bottom number, the more your vision differs from normal at that testing distance.

What each common value means

• 6/6 — this is considered normal vision (equivalent to the commonly known "20/20" in feet-based notation).
• 6/18 — noticeably reduced vision, though still functional for many daily tasks.
• 6/60 — significantly reduced vision. In India, vision below 6/60 in the better eye (even with glasses) meets the legal definition of blindness.
• 3/60 — more severely reduced; at this level, even large objects are hard to make out clearly from a normal distance.
• 1/60 — very severe visual impairment, though this is still different from complete blindness — it means large shapes or movement may still be perceptible up close.

Does this mean I'm losing my vision permanently?

Not necessarily — and this is genuinely important to understand. This number typically describes your uncorrected or best-corrected vision at the moment of testing, not necessarily a permanent condition. Many causes of reduced acuity, like refractive error (needing glasses), early cataracts, or a treatable eye condition, can improve significantly with the right correction or treatment. The number on its own doesn't tell you the cause — that's exactly what a proper eye examination is for.

What to do next

If your test showed a number like 6/60 or lower, the right next step is a full eye examination to find out why — not to assume the worst. Dr. Dhaval Patel will identify the actual cause and explain honestly whether it's correctable with glasses, treatable, or something that needs closer monitoring.
