Since I went Paleo 5 months ago, my right eye started being heavy, getting fatigued, and I often need to close it when starring at a screen. It doesn't happen much when I look far away, the problem is mostly when using my laptop, TV, or phone. I have a bit of myopia and lots of astigmatism, but I didn't have this specific problem pre-Paleo. The problem accentuated even more since I went Paleo-ketogenic 2 weeks ago. I don't believe I have "dry eyes" btw, just one fatigued eye.
I eat offal, fermented foods, and all other Paleo-allowed foods, MCT oils, and I ferment my own probiotic lactose-free goat yoghurt (I need it for my IBS-D). I supplement with D3, Mg, krill oil, K2, E, PQQ, Q10, and many other supplements (not all every day of course). I used to eat fruits and local raw honey when on plain Paleo (I was at around 100 gr of carbs daily), I don't have these on Paleo-ketogenic anymore (I do 25gr of carbs daily now). I switched to Paleo-keto because weight loss was just not happening for me on plain Paleo.
Is it the lack of carbs to blame (I know that eyes run on glucose, but then again, why does this happen only on my right eye)? I must admit that I don't drink as much water as I must btw, I don't like water here in the US (I find it... diluted). According to Cron-o-meter I'm constantly low on iron (65% of RDA on average), calcium (34%, and that's with yogurt in the mix, I supplement 2-3 times a week), folate (78%), B1/thiamine (69%). Any ideas of what's going on?

You might have CVS - computer vision syndrome - which is eyestrain at nearwork (computer, phone, tablet, reading, etc.) The greater difference in prescription between the 2 eyes (asymmetry), the more of an issue it can be. You need to take frequent breaks. It's the 20-20-20 rule. Every 20 minutes, move your eyes to look at something 20 feet far away (preferably window, hallway, etc.) for 20 seconds. I recommend using a timer to do this.
The blink rate drops for everyone with any amount of nearwork (computer, reading, etc.), and dries out the eyes. Artificial tears for lubrication can help, as well as fish oil supplementation for dry eye.
Sometime after age 38 (not saying you're this old), the eye muscles for focusing at near weaken and continue to with age. (This happens in hunter gatherer cultures as well). You might need computer/reading glasses/bifocals, etc. (they even have bifocal contact lenses). This processes actually starts after age 18 but is not noticeable until age 38-50.
There could be multiple issues going on. If your glasses are broken, bent, or not adjusted properly they can induce artificial astigmatism that forces the eye to work harder then necessary - causing eye strain. You may want to visit an optician to straighten or adjust the glasses.
VT (vision training/therapy) can sometimes help the 2 eyes work better together.
Sometimes people are overcorrected at distance, and this causes more eyestrain at nearwork, so they need the prescription reduced a bit.
If you are seeing double, and you have never seen double, that is an urgent visit to the eye doctor. You should visit an OD - optometry doctor (optometrist) in any case for this sort of issue.

Eug......got your tweet. I think the LED light can cause this. The answer above is good. But here are some other thoughts for you to consider with your doc. I know about your IBD and that concerns me this could open the door to AI diseases for you. We now know that IBD is a major gateway to AI. The two I want you to talk to your doc about are myasthenia gravis and internuclear opthalmoplegia which is often associated with MS. Also i would be concerned this could be mild bout of optic neuritis is also possible and is also associated with several earlier AI diseases.
A rarer presentation of an AI is JRA with eye weakness.
Most common reason could be atypical migraines (excess omega 6) Less common is rare viral infections like West Nile and herpes......etc.
A neurosurgical reason is a posterior communicating artery aneurysm. A neurology issue......TIA or a RIND ( i doubt but it could be tied to lupus dx because lupus is an AI and tied to many neuro signs in the eye. uveitis is another
That is all I can think of Eug. Tweet me if you need anything else.

Is the fatigued eye with the higher amount of astigmatism? I still get it on my astigmatism eye when I work too long (it happened before and after Paleo).

I have had this problem with fatigue in my eye with my right eye being the problem. I toon suffer from the TV, laptop, smart phone lighting and even the lights on cars at night. I feel this is due to a more dominant eye doing the work. I had all of this well before I began Primal eating. I have recently introduced Paleo (Jan 1,2012). I have not noticed a worsening of the eye fatigue in any way. I would make a suggestion that you see an OD...opthamalagic doctor as they can test your vision...not for 20/20 but for actual teaming, saccades and the like...how well your eye muscles work together with nerve impulses that they get from the brain when you want them to do something both conciously and subconsiously. There are actually exercise that can be done to support an improved neuromusclar response.
