Improve Sore Eyes when Reading and Studying
Do you get sore eyes from doing a lot of reading and studying? I had perfect eyesight for most of my life, though in the last few years this had declined. Here are a few things I found helped a lot, and my eyesight (and especially my close focusing) is much better now than it was a year or two ago.
If you're going to be doing a lot of reading, this is something you may run into problems with.
Reading Under Really Bright Light
This has really helped my eyesight a lot. I've been reading more books since I started Bible college, and many of them at a desk. I found that using two separate desk lamps, both quite strong, on the high setting, has hugely helped my eyes. It took a few months to really notice the difference.
This sounds so simple, almost too simple to bother with. But it really did (and still does) help my eyesight a lot.
Spend Some Time Outdoors in Full Bright Daylight
This is something else that I'm sure helps a lot with eyesight in general. Also, varying the distances you look at, such as looking out the window sometimes, can help a lot. Driving seems to be good for this also. Especially on sunny days. Too much UV rays can damage the eye, but this is the year 2020 (and I'm writing this while in lockdown for COVID-19), and more people spend more time indoors than perhaps any other time in the history of the world. I think that some amount of UV light is healthy for the eyes. I don't mean looking right into the sun, but just being outside and looking around normally in full bright daylight. Just as some amount of UV light on the skin is needed to get natural vitamin-D, and improves your mood, but too much will give you sunburn.
About 17 years ago, I was living in a downstairs basement room with very little natural light. As an experiment to save electricity, I tried not having the ceiling lighting on all day long in the daytime, like I had been. I found that after a few weeks of living in constantly dim light, my eyesight was noticeably worse. Things looked blurry sometimes, and it was hard to focus on things sometimes, and my eyes hurt sometimes. After I started lighting up the room more, these eye problems went away after a week or two and didn't return for about 15 years.
Dr Ray Gottleib Presbyopia Eye Exercies
I've found these help me massively also. You don't even have to do them very often (it says that on the PDF itself). You can get them from this link, which is working as of the time of writing this page. If that link fails at some time in the future try searching Google for ray gottleib presbyopia exercies pdf.
You're meant to print them out on paper as a hardcopy, though now that I've learned how to do them, I can do them (but noticeably less well) looking at the PDF on a computer screen. I printed them and got the main page laminated, mainly to help the page not get crushed up with use, but it also helps to hold it flat while doing the exercises.
There are two types of exercies, and both use the same chart. To begin with, use the upper section with the paragraphs that begin with the largest writing, that says "Cross your eyes to clear this print...".
One of the two types of exercises is called converging. Here you basically go cross-eyed, and read the text while doing so. This causes the page to take on a 3-dimensional look, where the middle column of text appears further away than the rest of the page (it looks about a centimetre further away, as if the text is floating above or below the page itself). This is the one the instructions ask you to try first. It took me a while to get the hang of the converging exercise, especially doing the converging exercise without using a pencil. Now I can do it pretty easily. At first (as the PDF explains) use a pen or pencil or some object to focus your gaze on, between your eyes and the page, to get your eyes working in the cross-eyed converging mode.
The other type of eye exercise you can do with the same PDF chart is called diverging. Here your two eyes move in the opposite way to cross-eyed, so that the point at which they would meet at is further away than the page itself. The instructions say to try this after trying the converging exercises, though I found when I first tried that my eyes naturally went into diverging mode very easily. It's the exact same action that you do with your eyes to see those computer-generated 3-D artworks that were popular in the 1990s, where the picture looks like a whole lot of random blotches of different colours, and then when you stare at it for a while, in the right way, suddenly you can see a 3-D image of a dinosaur or something. When these first came out it took me a long time before I could see them, but once I got the hang of how to do the right "look", I could see them easily every time after that.
The PDF is three pages long. The first two pages are instructions, and the eye exercise sheet itself is on the third page.
There are some other PDFs with different eye exercises found from a Google search. Some of these are also by Dr. Ray Gottleib. I haven't tried these ones, though they may also be quite good. This PDF is a longer one, also by Dr. Ray Gottleib, which I haven't tried yet — though it does contain on one page the same chart from the PDF above (the one I've been using myself) which is on page 16 of the longer PDF. However it doesn't have as detailed instructions on how to use that particular chart as the three-page one in the link above.
I tried the cross exercise on page 14 (of the longer PDF) just then, right after discovering it, looking at it on my desktop compute screen. I found that I could do both converging and diverging with it (after having much previous practice at doing these on the shorter version of the eye exercises PDF). I also noticed from the cross exercise that one of my eyes was focusing perfectly clearly and the other was a bit less than perfect.
