What will you find in the article?
Some time ago, Apple were one of the first to launch screen night mode, which softens the bright light of the mobile device.
This came about after it was found that blue-violet light has a negative impact on eye health and the body's perception of day and night.
As you already know, staring at a phone at close range puts strain on the eye muscles, or in scientific terms, accommodation (the eye's ability to focus from near to far).
What is accommodation?
Accommodation is provided thanks to the ciliary muscle, which through the ciliary threads, collapses and dissolves intraocular lens. Under this influence, the radius of curvature of the front surface is reduced, and this leads to a change in its refractive power.
And now you can just imagine silicone almond covered with elastics in the upper and lower corners. When you stretch the elastics, its shape elongates, and when you relax them, it becomes more plump. The force you exert when stretching the elastics plays the role of the ciliary muscle, the lattices the ciliary threads, and the silicone almond the intraocular lens. And now, add to all this the almond's ability to refract light.
And just imagine stretching and loosening those elastics all day long.
I personally would get tired pretty quickly. The same goes for our eyes. And this is just one of the activities they perform.
Why is it necessary to have Screen distance on mobile devices?
Accommodation load leads to the appearance of symptoms such as:
- Voltage;
- Headache;
- Blurred vision;
- Dry eyes;
The important thing to know is that the closer you read a text, the more you load the accommodation.
So, to protect our vision, Apple updated their version and added a distance control option.
How to activate the Screen distance feature?
It can be activated as follows:
Too close a viewing distance of the mobile device can increase the risk of myopia in the young.
In just the last few years, there has been a significant increase in the percentage of myopic people around the world, and this is, in large part, a result of the daily use of digital devices.
After installing the new IOS 17 version, you will be able to enable this feature on your phone. So you'll get a notification if you bring your phone too close.
Apple reports that the option will detect a distance of 12 inches, which is about 30.5 cm. We remind you that the generally accepted the reading distance is about 40-50 cm.
So, through "screen distance" you will protect your eyes from overstrain, building useful habits.
Note that if you use your phone at a closer distance than 30.5 cm, you will receive a message on the screen that covers the entire display and prevents you from continuing work unless you move your phone away.
The feature is extremely useful for young users, as they do not have well-established visual habits and do not realize the need for proper eye care.
And for those of you who haven't been teenagers for a long time, you can choose digital glassesto aid eye accommodation and reduce eye fatigue.
