Miks tekib pimedas telefoni kasutamisel ajutine nägemise kaotus?

Kui kasutate telefoni ühel küljel pikali olles, kohandab üks silm ekraani valgust ja teine tumedama valgusega. Pärast ekraani väljalülitamist satub aju segadusse, põhjustades ajutist nägemise kaotust.

Kas öine telefoni kasutamine võib põhjustada püsivat silmakahjustust?

Kui ajutine nägemise kaotus esineb liiga sageli, võib see olla püsiva silmakahjustuse tagajärg.

Milline seos on sinise valguse ja terviseprobleemide vahel?

Harvardi ülikooli terviseeksperdid on kinnitanud, et sinise valguse ja erinevate vähitüüpide, diabeedi, südamehaiguste ning ülekaalu vahel on seos.

Night-time Phone Use and Vision Loss | Advice from an Ophthalmologist Many people have experienced waking up in the middle of the night, reaching for their phone in the dark, and then noticing that one eye seems to see the screen clearly while the other appears almost blind. This can feel alarming, but in most cases there is a straightforward explanation. When you lie on your side in a dark room and use your phone with one eye effectively blocked by the pillow, that eye adapts to the darkness while the other eye adapts to the bright screen. When you then open both eyes, the screen-adapted eye struggles to see in the dark, creating the impression that something is wrong with your vision. This temporary difference in adaptation typically resolves within a few minutes. However, it is worth paying attention to any vision changes that do not resolve quickly, occur during normal waking hours, or are accompanied by other symptoms such as headache, eye pain, or flashes of light. These may be signs of a condition that warrants professional evaluation. From the perspective of general eye health, using a phone in a fully darkened room is not recommended. The high contrast between a bright screen and a dark environment places additional strain on the eyes and can contribute to discomfort, headaches, and disrupted sleep. Reducing screen brightness, enabling a night mode that limits blue light emission, and ensuring some background lighting in the room are all practical measures that can help reduce this strain. If you have concerns about your vision, consulting an ophthalmologist is always the right course of action.

The connection was discovered when two women, aged 22 and 44, visited an eye doctor because they had experienced several 15-minute episodes of vision loss. After many tests and examinations that did not reveal the cause of the problem, the doctors decided to conduct a lifestyle study of the women. Surprisingly, the causes of their vision problems lay in their lifestyle.

Why Does Temporary Vision Loss Occur When Using a Phone in the Dark?

It turned out that these women were very active mobile phone users in the dark before falling asleep. The problem arose from the dark environment and the position in which they were looking at their phone screens.

The women mentioned above used their phones while lying on their side in bed. This position creates a situation where one eye is fully focused on the screen while the other is partially hidden behind the pillow. As a result, one eye adjusts to the light of the screen, while the other adjusts to significantly darker light.

When the mobile phone is turned off or goes to sleep, the brain becomes confused and cannot understand why one eye has been operating in daylight mode and the other in night mode. This is why people experience temporary vision loss. If this occurs too frequently, it can result in permanent eye damage.

The Effects of Blue Light on the Eyes and Health

Most people underestimate the negative impact of mobile phones and computers on the eyes, but they should not. There is a clear link between deteriorating vision and the light emitted by screens.

We do not wish to alarm anyone, but health experts at Harvard University have confirmed that there is a connection between blue light (from mobile phones, computers, etc.) and various types of cancer, diabetes, heart disease, and excess weight.

Take care of your eyes!
