What Causes Permanent Eye Damage From Sleeping With The Lights On?

As we mentioned above, the reason why sleeping with the lights on is bad for your eyes is because when you’re asleep, you expose your eyes to bright light for a long time. Then, when you wake up, your eyes are already sensitive to light. This can cause your eyes to get “fried,” which is when your eyes’ light-sensing cells become overexposed, and damage can occur.

The following are some of the main causes of permanent eye damage from sleeping with the lights on:

Excessive Brightness –

The longer you sleep with the lights on, the brighter the light from the flashlight or computer monitor will be. This bright light exposure can cause permanent damage to your eyes through photo attention, which is when your eyes are stuck in a way that light sensitives are at risk of getting permanently blinded.

Excessive Light Exposure –

The amount of light you expose your eyes to while sleeping can also lead to permanent eye damage. During the day, you should wear sunglasses if you’re outside the day and you’re not staying at a hotel where it’s daylight for longer than a few hours.

Too much Salt in the Eyes –

When your eyes are under too much stress, they start to secrete more tears to ease the pressure, but too much of this is harmful.

Exposure to the Sun –

If you’re not wearing sunglasses, you run the risk of getting sun-damaged eyes. In other words, if you don’t wear sunglasses when in the sunlight, your eyes can be damaged. Similarly, if you sleep under the sun without wearing any type of eye protection such as a hat or sunglasses, your eyes can also be damaged.

The above are some of the reasons why sleeping with lights on can cause permanent eye damage to people. However, there are other reasons too such as:

Exposure to Glare from Bright Lights –

If you wear glasses while sleeping and then wake up with them on, your eyes could be exposed to glare from bright lights from your computer monitor or flashlight. This glare can harm your eyes and make them more prone to getting permanently blinded by light exposure.


In conclusion, sleeping with the lights on is a bad idea. It’s simply not safe, and it can lead to permanent eye damage. You should know, however, that there is no way to tell for sure if sleeping with the lights on is bad for your health. There are a few things you can do, however, to protect yourself against the effects of excessive light exposure while you sleep.
