'Looking up at the sky at 12 noon on Dragon Boat Festival helps improve eyesight', what do doctors say?

"It's blinding but try to keep your eyes open because I heard many people say so"

BSB account posted a video of putting lemon juice in the eyes and then looking up at the sky at 12 noon on Dragon Boat Festival to clear the eyes.

In addition, some accounts also instruct on looking up at the sky at 12 noon on May 5 to make your eyes sharper.

VTDH account said that according to family tradition, on the occasion of the Dragon Boat Festival, at exactly 12 noon, she stands and looks towards the sun. However, she did not know the meaning of this, only that it was too hot.

LDT account said that his childhood was associated with the memory of going outside at noon on May 5th to look up at the sky to wash his eyes. This was a habit that had been shared by his grandmothers for many years. According to him, looking up at the sky for 30 minutes would help wash his eyes.

A young man got lemon in his eye on the occasion of the Dragon Boat Festival.

"I don't know if it can be washed out, but after looking at it for a while, my eyes were dazzled and tears flowed," Mr. T. shared.

ML account also shared that although it was a bit dazzling, she tried to look away. This is what she heard from her grandmother.

No scientific basis, even harmful to eyes

Dr. and pharmacist Nguyen Thanh Triet, Deputy Head of the Department of Traditional Medicine, University of Medicine and Pharmacy, Ho Chi Minh City, said that the practice of many people to clear their eyes and wash their eyes has no scientific basis.

"Even lemon juice has a strong pH that can damage the eyes, changing the pH of tears. In addition, looking up at the hot sun at noon with high UV intensity can damage the eyes," Dr. Triet shared.

In recent days, the weather has been extremely hot and sunny across the country, with the UV index across the country at a high risk level. Therefore, Dr. Triet recommends that people pay attention to eye protection, avoid arbitrarily dropping acid solutions into the eyes, and look directly at sunlight as it can be harmful to the eyes.
