    Does anybody experience eye strain or eye fatigue from using their Passport Silver?

    But a guy got an aching shoulder about a week ago.

    You can adjust the color settings to find something friendly for your eyes:

    Settings -> Display -> Display Color Settings

    If you're going to be staring at the phone for an hour or more, yes - expect your eyes to get fatigued.

    I don't have one yet, so I don't claim it gives me eye strain, asking if anybody else has this, or if it's normal etc.

    I want to buy one, but I'm worried about the display quality. If it's possible to reduce blue light, that's great. The pixel density is fine as well. Contrast and brightness seem fine. I'm worried that Blackberry cut costs and used Pulse Width Modulation for dimming. Especially since the display is very bright at 100%, making dimming necessary.

    PWM might not be an issue, depending on whether it's combined with Direct Current and only used for the lowest brightness settings (if you don't use them anyway), or frequency (if the frequency is high enough, it might not have any negative effect on the user). Also, most people would not perceive flickering, but rather experience problems such as strain or fatigue.

    Hence the question. I would be grateful for your input.

    Your inane moralism is off topic. Is moralism or destroying other people's threads with off topic one liners and flaming 'cool' to you?

    Thank you for sharing your current disposition and concerns. If you did that in your original post, people would have had a good idea regarding the scope of your concern from the get-go. Be nice here - it's one of the few forums where civility aint totally dead, and that's because it's largely a network of productivity-minded professionals (many whose first language is not English) who visit this site.

    Regarding the topic (I do hw/sw/mech design), I have no idea whether BB chose a purely PWM or a PWM + constant current solution for display dimming on the Passport. If I were to take apart the device and trace down the parts associated with the display subsystem, I would be able to tell you quite easily, but I'm not going to take apart my Passport for that purpose.

    As you said, it is hard to identify the implementation given that there is no flicker. Assuming they used PWM only, I think they used an appropriately high enough switching frequency for users to not be strained regardless of the duty cycle.

    For your benefit I filmed and uploaded a little clip to show the differences between min and max brightness, and cool and warm white balance at min brightness - the case you are most concerned with. Find the uploaded file here: http://www.filedropper.com/mah00190

    I use the device on minimum brightness only and have not found any case of fatigue or strain after using the device for 1+ hours.

    Hope that helps, and again, be nice - you'll make friends.

    p.s. the Passport is the best mobile device on the planet (in my opinion). Get it!

    I haven't noticed any brightness or font difference in the SE or OG, I have been using my Q10 for the last few weeks and talk about eye strain.

    With the Q10's size and a privacy screen this is eye strain.

    Switched phones for a bit just because, but as stated you can toggle the screens brightness and warmth levels on the Passport.

    For me I DO get eye strain, but In my honest opinion this is due to overuse of it..... because of the size screen and long battery life, I tend to find myself using the gnews reader a lot and catching up on news etc, I also read kindle books and will stream youporn *cough* I mean youtube videos, though I use my computer at work a lot, I have not turned on my home PC in a few weeks, as I just use my phone?

    This would probably have been better as your original post. Your original post didn't go into enough detail to answer your question adequately.

    I do not have any issues with eye strain with my Passport, and that is coming from a Z10. I prefer reading on the Passport, although the display on the Z10 was great. I am 51 and can read the display without reading glasses if I need. I do not have text set large either. I think you will be fine if you choose to use one.

    Sorry mate. It was meant to be a joke, to get lighten up when straining under fatigue. No offensive intention. I'll make sure to add some smileys next time.
    I've no serious answer to your question. But it is appreciable that you are serious about your Passport consideration.

    Eye strain occurs when viewing computer or other digital/electronic screens BECAUSE our blink rate goes down and eyes don't get hydrated without blinking. Learn to consciously blink more when viewing electronic screen and eye strain will reduce.

    What a CLASSIC!

    Thanks for the feedback. The video clip was interesting. Having developed sensitivity to PWM flicker, I already knew after seeing it that I should avoid the deal I had, and a few days later I got confirmation from Blackberry Help on Twitter that it does use PWM. I bought another phone without PWM. Thanks again!

    No strain, my friends with iPhone 6 think my passport's screen is better, it seems to be a particularly decent one, i wouldn't worry about it. I've even read a whole book in it in one sitting, no eye strain.

    Hello adjusted in display settings Color white more toward warm. This helps when in dark environments not to get a very cool right white.
    Works great.

    Yes there is a slight work around
    From settings select accessibility and turn on magnify mode

    Now at any point you can pinch in zoom in and magnify and pinch out to reduce. This feature can be used anywhere like the icons you mentioned.
