How To: Calm Your Alarm Clock's Display and Sleep Better for 25 cents

I'm a terrible sleeper. I struggle with falling asleep, and staying asleep. I got it from my dad, and I've tried meditation, different levels of mattress and pillow softness, earplugs, heavy curtains, and everything I can think of. And I've learned a few things over the years of trying to feel rested: I need a little bit of distraction to occupy my mind to fall asleep, and once I'm there, I need an absolutely black and silent room to stay that way.

Thusly, I did everything I could to not upgrade my alarm clock I'd had since I was ten. Not an analog clock with hands (the ticking drives me nuts), but a basic, electronic LED red alarm clock that told me the time, had a non-distracting face, and stayed out of the way. 

And then it broke, and I needed a new one. So I went to the store, and bought a basic, simple replacement. And it glowed like a freaking train engine. I mean it: I could read by the light of this thing. So, I took it back, and tried another. Same thing. See, most contemporary alarm clocks are lit by LCDs, and apparently, LCDs are really bright, and I mostly hate them.

It took four more alarm clocks, and I finally found an alarm clock that has an adjustable brightness. Brilliant! Plus, I can charge my phone and listen to music with it. But, it's still pretty bright in an otherwise dark room. Luckily, I came up with a solution that helped immensely, for only a quarter.

Materials and Tools

  • Alarm clock
  • Measuring tape or ruler
  • Semi-transparent, colored plastic binders dividers ($1.19 for 5 at the office supply store)
  • Scissors and/or craft knife

1) Begin by measuring the display of your alarm clock. Don't just say, "It's roughly 3 x 1 inches;" be very exact, and don't be afraid of figures like "19/64s".

2) Cut a strip the same height as the display, and then cut it to length. My display has rounded corners, so I tried to mimic that.

3) You might be lucky, and the new "diffuser" might stick by static cling. Mine didn't, so I spritzed just a little water on it, let it nearly dry, then smacked it on. It's stayed in position for two weeks, and doesn't seem like it'll go anywhere.

Here are two photos to compare the difference. Of course, it's tough to take pictures of a tiny light source in the dark, but here's the alarm clock before and after, using the same exposure (F1.8, 1/60, ISO 1000) on both images. As I mentioned above, the clock does have an adjustable brightness, but both of these are taken on the dimmest setting, I promise. (You can see that the lighted buttons above are the same)

And with the addition:

It may not look like a huge difference in the photos, but in a dark room, it's like night and day. Sorta literally... It does change the color, which I think actually helps, but the biggest difference is in the reflections. Without the addition, the light bounces off my dresser and the walls the surround it, lighting up the whole corner. With the binder divider attached, the reflection is calmed a lot, and the overall brightness is much subdued. You can still see the numbers clearly at nighttime and during the day.

Pretty sweet, huh?

I know what you mean. The leds are way too bright. Bright LED Shades makes an adhesive plastic that covers over the led to cut way down on the glare. Nice and sleek. And it pulls off without any sticky residue. Just a thought.

Thank you!!!  This has been driving me crazy for years and I usually just drape a tissue or 2 over it to block the light.  Glad to know I'm not the only one that likes it completely dark at night.

Fantastic idea!! Thank U! I can toss the dark washcloth covering my clock and now my hubby can see the time without it shining like daytime!

I tried using window tint. Don't buy it though, (seriously, you'll buy 12 yards for a small piece?) just find a place that does window tiniting and cut a piece out from the scraps they toss in their dumpster. FREE! But I am going to look into the plastic folder option for my new clock.

I have an extra eye sleep mask. I put that around the alarm clock. It blocks all the light. And really, I don't need to know what time it is until the alarm goes off!

I have had a travel clock for years that speaks the time when I press the top; I use this to get the time in the middle of the night if I need it.  I've read, however, that our brain/body requires complete darkness to re-set  and get genuine rest so I just cover my new bright alarm clock (that emits a very quiet foresty or beachy white noise for a pre-set time) with a dark blue fabric every night and I don't keep any other electronic gadget in the bedroom.

I had the same situation years ago... I didn't think of the plastic folder covers... great idea.  What I used was colored cellophane (on a roll, for wrapping gift baskets, or floral bouquets, etc)... I folded it several times, and tested the thickness against the clock to see how thick to make it to dim the numbers enough.  When it was thick enough, I cut it to fit, and used double stick tape to secure the layers together, then dub-stick tape to secure it to the clock window.  It worked great for many years til I bought new clocks.  I just wish I could come up with something for my Visio tv in the bedroom... it has bright Visio lettering that comes on in the middle of the screen when the tv is off.  I can't cover it without interferring with the picture screen.  grrr  I'll never understand why some electronic manufacturers do this to their consumers.  I love the tv... but wouldn't buy another one due to that one irritating feature!

Hi there. I'm posting to say, first of all thank you for the idea! I managed to calm my alarm clock but I made a slight change to make it even neater. Basically I took apart the alarm clock. On mine the display is mounted on a flat circuit board that's screwed into a plastic frame with a square hole in it for the display. I basically cut a dark blue copybook cover twice as large as the hole, folded it in half (to get double thickness, because it's a VERY bright alarm clock) and put it in the hole. Then I placed the display on top of the plastic, screwed it in and reassembled the alarm clock. So basically in front of the display I have the copybook cover, but it's all inside the clock - so the advantage of this method is that once assembled the clock actually looks no different than a regular alarm clock! And the only way to dislodge the plastic is to take apart the alarm clock again :) Thanks again for the tip.

I just put regular scotch tape over the face of my clock, and electric tape over the standby lights on all the electronics in my bedroom, including the face of the modem.

This is awesome! I was actually thinking of buying window tint, but I'm guessing it's a bit more pricey.  I have had my old alarm clock for 18 years.  It still works, but it was time for an update.  I am doing this tomorrow! Thanks for sharing!

I bought an iHome alarm clock and part of the brightness setting is a backlight off for complete darkness.  No need to mod.  If you do need to mod one however, it wouldn't be to hard to open up the alarm and add a potentiometer to adjust the voltage going to the brightness.

Oh, this is much nicer than the bit of black garbage bag plastic I taped to the front of mine. :D

Awesome! I did this same thing years ago (out of necessity) to my super-bright alarm clock, but I used old film negatives (ones that were over/under exposed so they had no images on them). Worked great!

Great idea- I'm glad (I think!) to be mentioned in another article!

What a great idea!  Thanks!

Graham that's what I was thinking that would work too. You find it or other brands in any baby department.

I have migraines so I always have some long dark cuffed knee highs that I tie around my head to keep things dark and my  head from exploding. If the head isn't hurting too bad I just circle my clock with the sock. The only problem with that is you have to remove the sock to see what time it is and then get blasted with bright light.

Another option would be to use Eddie Bauer Cling Sun Shades.

It's about $4, and you don't have to use tape.

Window tinting film is an excellent idea. Where does one find some? The auto supply store?

I had some extra window tinting film and put several layers on that until I was satisfied with the light output...........or lack thereof!

I love your idea though!
