Does blue light speed blindness? Here are 3 things that may help prevent damage.

I recently read an article that stated blue light could speed blindness.  We all know that technology we look at emits blue light so how serious is this?

Problem

Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo.

According to the article, blue light can not be reflected or blocked by the eye’s cornea which then damages the retina and can result in macular degeneration.  Macular degeneration is a disease that results in the death of photoreceptor cells in the retina and eventually results in blindness.  The blue light exposure generates poisonous chemical molecules in photoreceptor cells.

“Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good.” – Kasun Ratnayake, a Ph.D.

Solutions

  1. Researches say that Vitamin E (alpha tocoferol) can help prevent these cells from dying but as we age the immune system is depressed and we lose the ability to fight against the attack by retinal and blue light.
  2. Protect your eyes from blue light by wearing sunglasses that can filter both UV and blue light outside.
  3. Avoid looking at your cell phones or tablets in the dark.

It’s very important that we pay attention to the positive and negative impacts technology can have on our social, physical and spiritual health.

The Evolution of Code Deploys at Reddit

We’re constantly deploying code at Reddit. Every engineer writes code, gets it reviewed, checks it in, and rolls it out to production regularly. This happens as often as 200 times each week and a deploy usually takes fewer than 10 minutes end-to-end.

The system that powers all of this has evolved over the years. Let’s take a look at how it’s changed (and how it hasn’t) over all that time.

Growth Idea: Make it easy to invite friends!

I recently viewed the @coinbase onboarding process and noticed a very nice “invite friends” link easily and readily viewable in the top nav.  This is a great idea and one I think a lot of sites are not doing but should!

My Thoughts:

One additional thing would be to add video and provide ideas of how you could share with friends.  #coinbase provides the gmail, share, tweet buttons but they also need to help people with ideas of how to share.  Providing some videos of ideas or a articles/ebook would be great!  Also adding text messaging would be critical, it’s the fastest way to hear and be heard!
