Kita sering didedahkan dengan penggunaan telefon bimbit dalam kehidupan seharian. Tetapi tahukah anda, cahaya biru yang dipancarkan daripada telefon bimbit mampu menjejaskan penglihatan?

Kajian yang dilakukan oleh  University of Toledo menunjukkan bahawa kornea dan kanta mata tidak mampu memantulkan kembali cahaya biru yang dipancarkan oleh telefon bimbit.

cahaya biru pada telefon bimbit boleh butakan mata - kajian

Photoreseptor yang terletak dibahagian mata akan menghantar signal ke otak. Apabila kita menghadap cahaya biru, sel photoreseptor ini akan mati, dan sel tersebut juga tidak bercambah seperti sel-sel yang lain.

Semakin banyak cahaya biru yang masuk ke mata, semakin banyak sel photoreseptor yang mati, menyebabkan penglihatan kita terjejas.

  1. Aw, this was a very nice post. Taking the time and actual effort
    to produce a superb article… but what can I say… I hesitate a whole lot and never seem to get anything done.

  2. Today, while I was at work, my cousin stole my iPad and tested to see if
    it can survive a forty foot drop, just so she can be a youtube sensation. My apple ipad is now destroyed and she has 83 views.
    I know this is totally off topic but I had to share it with someone!

  3. Greetings! I’ve been reading your blog for a long
    time now and finally got the bravery to go ahead and give you a shout out from Atascocita Tx!

    Just wanted to say keep up the excellent job!

  4. Hey there would you mind sharing which blog platform you’re using?

    I’m going to start my own blog soon but I’m having a difficult time
    making a decision between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design and style seems different then most blogs and I’m looking
    for something unique. P.S Apologies for getting off-topic but
    I had to ask!

  5. Hi friends, how is all, and what you wish for to say on the
    topic of this paragraph, in my view its really remarkable in favor of me.

  6. I absolutely love your blog and find many of your post’s to be precisely what I’m looking for.
    Would you offer guest writers to write content for you personally?
    I wouldn’t mind publishing a post or elaborating on a few of the subjects you write related to here.
    Again, awesome blog!

  7. Hi there! I just wanted to ask if you ever have any problems with hackers?
    My last blog (wordpress) was hacked and I ended up losing a
    few months of hard work due to no back up. Do you have any solutions to prevent hackers?

  8. Greetings! Very helpful advice in this particular post!

    It’s the little changes that produce the most significant changes.
