Ocushield Anti Blue Light Tempered Glass Screen Protector for iPhone 7 | iPhone 8 - Protect Your Eyes Reduce Migraines & Improve Sleep

I’ve been using the Ocushield Anti Blue Light Tempered Glass Screen Protector on my iPhone 14 Pro Max for a few months now, and I’m genuinely impressed. The installation process was straightforward, and the fit is precise—covering the screen edge-to-edge without interfering with the front camera or Face ID functionality.What sets this screen protector apart is the blue light filtering. After long days of screen use, I’ve noticed significantly less eye strain and better sleep quality, especially when using my phone at night. The display remains crisp and vibrant, with no noticeable color distortion.On top of that, the tempered glass offers solid protection. It’s handled minor drops and scratches without any damage to the screen underneath. The surface feels smooth and responsive, maintaining the premium touch experience of the iPhone itself.If you’re looking for a high-quality screen protector that not only defends against scratches and drops but also actively supports your eye health, I highly recommend Ocushield. It delivers on its promises.

Before I start, I am not in any way affiliated with this company, I'm just a customer who chanced upon the product.I have eyes that do not like bright lights especially blue light. Signs and text that are lit blue at a distance appear as a blur to me (worse if the source light is an LED) while all other colours appear very sharp (I do not require prescription lenses to see clearly at any distance although a very mild correction does perceivably benefit me at all distances.)When the world shifted from CCFL (fluourescent backlit with UV (invisible) source light) to LED backlighting (blue LED with a yellow phosphor to absorb that blue light and fluouresce yellow) I found myself with unbearable eye fatigue whenever looking at a white LED backlit display of any kind.Some research later I discovered that is because the white light emitted by white LEDs is the product of a mix of blue and yellow photons only, it is not a full spectrum white like sunlight or RGB light, it has a massive spike of blue light in the 450nm wavelength and dropping off sharply but still present either side of that. This is the exact point of the visible spectrum that causes people with weak eyes like me to experience fatigue when we expose our retinas to that short wavelength of light due to its high energy.Other display technologies such as OLED/AMOLED have base light sources of a mix of red, green and blue LEDs in order to produce white, this results in a balanced and less optically obnoxious white that my eyes (and i'm sure many others) have a much easier time dealing with. (there is the PWM issue with OLEDs but I won't cover that here as it is not relevant)Why not just always use old CCFL monitors, and OLED devices and non white LED backlit displays then? In today's world that is impossible, the majority of displays we interact with on a daily bases are lit by white LEDs and produce other colours purely by filtration of that light, therefore the harsh light must be attenuated or avoided entirely for me if I want to keep my eyes in good health.Night modes on displays apply filtration to the base light, yes they can make your screen go all warm and amber by bathing the image in warm colours, but it does not and cannot stop a bunch of those blue photons from hammering into your eyes as the material in an LCD allows them to pass freely (it has to in order to display colours accurately).This product, I cannot tell you to what precision it attenuates the light, but it objectively does so. I can view my iphone 8's display which used to fatigue my eyes in a matter of a few minutes of use for normal use now without feeling that anywhere near as much. It was worth the money for me it has turned reliance on OLED mobile devices into that potentially not being the case.The only negatives I can state are definitely par for the course with this product, inherent to it's purpose and should not be regarded as flaws. They are as follows.Blue/Mauve tint to the device screen when tilted any direction but straight at you.Slight (and I do mean slight, slighter than night shift on less than a quarter of the way) yellow tint to the image, the marketing material stating that it doesn't affect the image at all is not 100% accurate (I expected this).Overall, good work on creating a product to address this issue, while I believe the general population does not experience fatigue to the point of going out and seeking a product like this, I do believe they could benefit from its use.

Before I’d even started peeling the film back, the protector was broken/cracked! I thought I would try to use it anyway, because I didn’t want the hassle of a return and needed a protector asap, so I started peeling the film back, and then it broke much worse! Looking at the picture of step 1 in the instructions in detail, it looks like there is supposed to be a tag to help you peel the film back. There was no tag on mine, so I had to try to find an edge to pull up the film. But it was so tightly stuck that I had to apply pressure to pull it off, and at a certain point the whole screen protector splintered, as you can see in the second photo. So it seems that I have a bit missing on the product I was given, but it also seems that the design (and instructions) are rather poor: I don’t think it should break so easily when assembling - I wasn’t doing anything unusual: indeed, I was being careful.

The experience of application is very good. The packaging and material of the product is high quality.It says it blocks “99% of blue light in 300-400nm range” which is a gimmick since 1) OLED iPhone screens produce hardly any light in this range and 2) the eyes are mostly affected by light in 460-490nm spectral range.It also says it reduces “up to 40% of light in 400-470nm range” which is the real application of this product.The screen was not considerably tinted towards yellow, perhaps a tiny bit but it’s imperceptible, which is nice. The problem is it reflects loads of blue light back at you from the surrounding environment which reduces readability, requiring the screen brightness to be higher in some cases which mitigates the overall effect.I’m not sure if this is improving the situation by much for £25. I’ll see how it goes, but I wont stop using night mode and reducing brightness.

This is the second phone I’ve installed an Ocushield on. The blue light blocking seems to work. I fall asleep easily after using the phone even at night. The reason I say it works is because I didn’t bother to put one on my new phone for the first few weeks and I immediately noticed I was not getting to sleep after using the phone. Put the ocushield on and the problem disappeared. same thing when I got the first one. So seems like too much of a coincidence to be happening by chance. Works for me anyhow. I think it’s a bit pricey though. £10-£15 would be a better price.
