I am a part time betfair trader but i have a full time office job that requires me to sit in front of the computer all day. The working hours can be punishing when volume peaks.
On a typical day, I face the computer from morning to evening (sometimes till night) and then i go home , have my dinner, turn on the computer and use use whatever time left to trade. So i am facing the computer all day long.
Over the years my eye sight is getting bad. While my myopia has stabilize and isnt getting worse, my astigmatism is. I am starting to see sparking lights in the dark.
I am trying to cut down time spent looking at computer LCD screens. I was thinking of investing in a projector. A projector does not emit light but rather reflect lights so it shouldn't hurt the eyes. What do you all think?
Eye sight getting bad due to long hours staring at screen

I do sympathise. BA is a great product but it irritates the hell out of me that they have made it incompatible with Windows DP scaling. For my eyesight's sake I use a large DP scale (it makes everything bigger while still keeping it sharp) but it means that some part of BA just don't show correctly.
I can't usually answer any questions with authority on this board but as an optometrist with 22 years of practice and continuous education behind me FINALLY I've got one I can handle!
1. Good news...
Your screen use is having absolutely no effect on your eyesight whatsoever. The photons of light hitting your retinas from the screen are exactly the same as the photons of light from any other light source and they have no ability to reshape your eyes (astigmatism is where the eye is a slightly ovoid shape rather than spherical).
However, the shape of every part of your body does go through changes due to natural ageing processes and eyes are no different; it's just different changes at different times of your life.
2. Less good news...but still not bad....
Seeing sparking lights in the dark is frequently a sign of posterior vitreous detachment. Again, it's unrelated to computer use and usually it's a condition which runs a natural course with no long-term ill effects.
It typically happens in most people before the age of 70 but generally tends to be earlier in the myopic eye. Inside the eye is a ball of jelly-like material called the vitreous gel. Running through it are collagen fibres and it is attached strongly at the front of the eye and much more weakly at the back of the eye.
With age, the collagen fibres tend to shrink and contract and this causes the ball of vitreous gel to pull away from the weaker attachments at the back of the eye. It remains attached strongly to the peripheral retina at the front of the eye and the fact that the poterior portion is detached means that the vitrous gel can move around slightly. This causes the strongly-attached area to "tug" gently on the retina as it moves and this can cause you to see sparks or flashes. Normally they subside over a 6-8 week period but can continue a lot longer if you're unlucky.
Occasionally (around 2% of cases) this can cause a small hole or tear in the peripheral retina which, if left untreated, can lead to retinal detachment and this can cause serious and rapid vision loss. If you have had this symptom for less than six weeks, I'd recommend getting them checked.
Other possible causes of seeing flashes of light are migraine (although this is usually accompanied with other symptoms such as headache, nausea and light sensitivity) and entoptic phenomena which are random neurons firing within the visual system. Neither of these have any long-term consequences although they can be annoying.
Hope this helps...

That post has just confirmed something of which I was recently very suspicious.
I had my eyes tested and I was told that they were actually in better shape (being the operative word) than they were at the time of my last test - about six years ago. I've had glasses for long distance (driving, etc.) for the last forty years and I never needed to remove them to read. Now, although I don't absolutely have to, I find it easier to remove them if I'm trying to read something on my phone, but I don't have a problem on the computer, even though the font size is the same (I checked)...

Bad move Steve, you're now the Eye Guy on this forum!
Years ago I got an analysis of "possible symptoms of glaucoma" because of the pressure test thingy when they blow the blast of air into your eye? High pressure. Not naming companies, but I told the present eye-o-logists their view and they said...WHAT??? Should have NOT gone to Specsavers that time!

1. Almost every of my colleague i spoke to told me that their eyesight has gotten a bit worse over the years working in this job, so i believe working with computer screens for prolonged period do have a detrimental consequences on the eye?
2. I dont think thats the case as i am only 26. But i will do a check up. Thank you.
Thanks for your expertise. But do you not think there is some merit in investing in a projector? the distance between image and my eyes would be longer than using a computer screen. Based on my experience my eyes feel more comfortable looking at distance object for long period.
Also how much can bilberry supplement help? I am planning to take some.
