The smart phone and your vision

Is 'sh!t-ton' a standard or metric unit of measure?

LED monitors and TVs are bad on the eyes too. It is not just the smartphones, there is a lot of evidence that verifies eye degenerative diseases being related to LED

Thank you for backing up what I wrote.

Actually my statement on this thread was about an eye doctor on TV yesterday showing how eye disease is or can be a result from using the smart phones and was shown with all the instruments on how the disease progress with no cure if caught too late.

Us old timers remember when color tv came out, the first thing the sales person said "don't sit close to the TV", I still remember them words.

It is advise that you keep 30cm away from reading your smart phone.

This is America, no one uses that stupid Metric System here! But if we did that's like 50 feet anyway so how would we even see the screen?

The whole world uses centimeters - even in the US science uses the metric system.

Learn it :

30 centimeter is about 12 inches.

No! It's stupid! Plus I like having to check difficult conversions online.

The frequencies of the LED are very intense in the visual spectrum they target. They can cause permanent eye damage, especially to old people. We are bombarded by this light, even the lightbulbs have the bright frequencies. We only buy the softer LED lights for our house and some of our bulbs will remain the traditional ones.

That is totally correct, blue light LED's are actually the worst culprit's of this and traditional incandescent bulb's while using more leccy are a lot less harmful to our eye's.
Not sure but if I remember there was some claim that OLED are actually also better than normal LED in the spectrum they produce and potentially less harmful but given they are a later technology that may simply be down to better engineering of the end product.

I heard that excessive use of phones and other gadgets can cause myopia.
