Can you only use this a night or can you see the words during the day?

I used it at night. But yes you can. I didn't have any reactions. But I didn't like the results. Especially for the price.

I think you could set it to have an hourly announcement - but the one I got my mother...she just pushes the button and it announces the time. This is an excellent product for a person who has deteriating sight. She loves it.

Nope, you can only use it in the day time as the light sensors wont allow it to properly attach to your camera at night

I'm not sure because i've online used it at night! But I don't believe it works well for that.

Usually just during the day and evening. It would make a good nightlight, I just hadn't thought of using it that way.

You can set the switch so that it runs constantly, which will allow it to be on during the day. But if you do that, it's no brighter than a real TV seen during the day, which isn't very noticeable. And of course, unlike a real TV where someone might be able to see the screen during the day, with this product there's no screen, so you have to position it so it can't be directly seen from outside.

I would recommend only using during the night .. It may be too heavy for normal skin during the day

Yes you can, though it's relatively dark and of course changes the colors. I bought this after reading about the effects of blue light on circadian rhythms. I didn't have a good way to temporarily attach this to my laptop, so I opted for amber glasses at night instead.

You can leave it on but it doesn't read continuously. You have to press a button to get the current reading. Therefore, there is no point in leaving it on unless someone is going to press the button and check on it at intervals during the night.

Personally, I use very little ( once a day) at night. There are times I use it two times a day , if I'm going out to a dinner engagement or something like that.Use a dime size of a tad more & it should last a few months.I hope I was able to be of help.Cheers!

Yes, these are for use at night. And then you need a different one for the day. And a sunscreen.

Yes but you can't see this sign during the day only at night! Only worth the money if you are only open nights.

Hi, I can't see it at night. I have good eyesight and frustratingly, through the years I have been gullible enough to purchase different brands of these NON-seeable clocks!! Also, the onesthat are seeable require that you reach for the clock and press a button...how ridiculous is that on a cold night?...A highly Un-recommended product.

The light power is adjustable. I don't know the technicality of it, but you should be at a distance where your eyes can look at it occasionally. You need to use it for approximately 30 minutes in the morning or afternoon.
