Fact or Myth: Does Walking Barefoot on Grass Improve Eyesight?
Verdict: Myth, with a twist. Walking barefoot on grass does not change the shape or focus of your eyes, but the daylight you get while you’re out there really does help protect children from becoming short-sighted.
In brief
- Verdict: Myth for eyesight. No foot nerve runs to the eye.
- What is true: time outdoors in daylight lowers a child’s chance of developing myopia (nazar ki kamzori for distance).
- What to do instead: get children outside for about 2 hours a day, keep regular eye tests, and wear chappals where the ground is dirty or you have diabetes.

Dew on the lawn at Fajr. A grandfather telling his grandson, “Nange paon ghaas par chalo, nazar tez hogi.” Does walking barefoot on grass improve eyesight? No. Glasses won’t come off. But the old advice points, almost by accident, at one of the few things that genuinely protects young eyes, so it’s worth understanding before you dismiss it.
Where the belief comes from
Several roots here. Ayurveda teaches that the feet and eyes are linked through channels and marma points, and padabhyanga (foot massage with oil) is traditionally praised for the eyes. Reflexology maps draw an “eye zone” under the toes. Hakeems speak of cooling the body’s heat, and cool, wet grass feels like the most cooling thing on earth. Then there’s the colour green, long said to rest the eyes, which is why generations of students were told to look at the trees in the courtyard between chapters, and why green walls once filled clinic waiting rooms and school classrooms across the subcontinent.
Add a slow morning walk in fresh air, birds loud in the neem tree, the city not yet awake, and it feels wonderful from head to toe. No wonder people love it.
These traditions deserve respect as traditions. What they describe, though, is a feeling of calm and freshness, and a feeling isn’t the same as a change in how light focuses inside the eye.
What the evidence actually shows
Think of the eye as a camera. Simple. Sharp sight depends on the length of the eyeball and the curve of the cornea and lens. In short sight (myopia), the eyeball has grown a little too long, so distant things land in front of the retina and look blurry. Nothing travelling up from the soles of the feet can shorten an eyeball. Impossible. The nerves in your feet carry touch, pain and temperature to the spinal cord and brain; the eye’s focusing muscles get their orders from entirely different nerves in the head.
Reflexology “eye points” have never been shown to change a glasses prescription. Neither has grounding (earthing). Same story. Green colour isn’t special either; looking at anything far away relaxes the focusing muscle, whether it’s a tree, a minaret or the horizon.
Myth: nange paon ghaas par chalna can fix weak eyesight
It can’t reverse myopia, long sight, astigmatism, cataract or age-related near-vision loss (the reason people over 40 hold the phone at arm’s length). Anyone who stops wearing prescribed glasses in the hope that morning walks will take over only ends up squinting, with headaches, and a child may fall behind at school. For the full list of eye totkay and what they really do, see nazar ki kamzori and the eyesight myths.
The part that is true: daylight protects children’s eyes
Here’s the twist. Eye doctors worldwide agree that children who spend more time outdoors are less likely to become short-sighted. Why? Daylight. It’s many times brighter than indoor light even on a cloudy day, and that brightness, together with looking into the distance, seems to slow the eyeball’s growth in length. Grass adds nothing. A child on a rooftop, a cricket pitch or a school playground in shoes gets the same benefit.
So the grandfather’s walk helps. Wrong reason, right habit.
The eyes benefit from the sky above the grass, not the grass under the feet.
Did you know? Myopia is becoming far more common in children across Asia, and eye specialists link it strongly to long hours of close work indoors and less time outside.
What to do instead
- Two hours outside: aim for around 2 hours of daylight outdoors each day for school-age children, in shorter chunks if needed. Avoid the harshest midday sun in summer, and use a cap.
- 20-20-20 for screens: every 20 minutes, look at something about 20 feet (6 metres) away for 20 seconds. Our 20-second screen break explains the habit.
- Reading distance: keep books and phones about 30 to 40 cm from the eyes, in good light.
- Eye tests: a child’s first full eye check before starting school, then yearly if they wear glasses or have short-sighted parents; adults every 2 years, yearly with diabetes.
- Wear the glasses: as prescribed. They don’t make eyes “lazier” or weaker.
- Enjoy the grass safely: barefoot on a clean, known lawn is fine for healthy adults and children. Check it first for glass, thorns and droppings.
People with diabetes should not walk barefoot anywhere, grass included: reduced feeling in the feet means a cut or thorn can go unnoticed and turn into a serious ulcer. Check your feet daily with our diabetic foot check routine. In villages and on soil where people or animals relieve themselves, bare feet can pick up hookworm larvae through the skin, which can lead to anaemia, so wear chappals there. A deep or dirty puncture wound needs a doctor about tetanus cover. For the eyes, see an eye doctor the same day for sudden loss of vision, a curtain or flashes with new floaters, a painful red eye, or double vision; see one soon if a child squints, sits very close to the TV, or has a turned eye or a white reflex in photos.
Barefoot walking and eyesight: common questions
Does walking barefoot on grass improve eyesight?
No. There’s no nerve or channel from the soles to the eyes, and grass can’t change the shape of the eyeball. Being outdoors in daylight does help protect children against short sight, shoes or no shoes.
Can nange paon chalna remove my glasses?
No. Glasses correct the eye’s focus. Walking can’t. Stopping glasses usually just brings headaches and strain.
Is there a nerve between the feet and the eyes?
No. Foot nerves carry sensation to the spinal cord and brain. The eyes are supplied by nerves that come directly from the brain.
How much outdoor time do children need for their eyes?
Around 2 hours a day of daylight outdoors is the figure eye specialists commonly suggest, and it doesn’t need to be sport or anything organised, because simply being outside in bright natural light, reading on a verandah or playing in the gali, counts. It can be split across school breaks, play and walks.
Does looking at green colour help the eyes?
Looking into the distance relaxes the focusing muscle, and it’s pleasant, but green itself has no special power. A far wall or skyline works the same way.
Is walking on grass in the morning good for health?
A morning walk is excellent for mood, fitness and sleep. Doing it barefoot on a clean lawn is fine for most people; it just isn’t an eye fix.
Can people with diabetes walk barefoot on grass?
They shouldn’t. Nerve damage can hide small cuts and thorns, and with slower healing and sometimes poor blood flow to the feet, a tiny wound nobody noticed on Monday can be a deep, infected ulcer by the end of the week. Soft, closed footwear is safer.
Can you get worms from walking barefoot?
Yes. Where soil is contaminated with human or animal waste, hookworm larvae can enter through the skin of bare feet. Clean, well-kept lawns carry much less risk.
Does grounding or earthing help the eyes?
No. Grounding hasn’t been shown to change vision, and claims that it does belong with the marketing.
Does padabhyanga foot massage help eyesight?
It’s relaxing and can help you drift off at night, and Ayurveda has valued it for the eyes for centuries as part of a calm evening routine, so enjoy it for what it gives. It won’t change your glasses number.
Can adults reverse myopia naturally?
No. No home method reverses it. Glasses, contact lenses and, for suitable adults, laser surgery correct it; an eye specialist can explain which fits you.
When should a child have an eye test?
Before school starts. Sooner if they squint, rub their eyes a lot, tilt their head or sit very close to screens.
