computer vision syndrome

[paglamon]

This is for all the computer buffs here.It is now an established fact that prolonged viewing of TV,computer screens cause some complaints that can be attributed to Dry Eyes.When we look at the screens with concentration we blink less frequently.Now blinking has a two way function.Firstly it stimulates tear production from the lacrimal glands.Secondly it helps to spread the tear film uniformly over the anterior surface of eye.So a decrease in blink rate produces some amount of dryness of the eyes.The common symptoms are gritty sensation,burning eyes,redness of eyes and reflex watering.An easy solution is to consciously blink more frequently while in front of computers.U can also try to splash some water on ur face and eyes at 30-40 min intervals.But a more practical approach is to have an artificial tear substitute (preferably preservative free) on ur table and just put one drop into each eye every 40 min and continue with ur work.
It is predicted that Computer Vision Syndrome will become a major cause of dry eyes in a few years.And dry eyes can gradually lead to more serious complications involving the cornea of the eyes.So,please take care of ur eyes and prevent DRY EYES.

I agree with paglamon, this was proven years back and is a scientific study.

i have them right now, it almost stings to blink...must go to bed. you are a very smart man paglamon.

[drfsupercenter]

Wow, I have this "nervous tic" of blinking too much so I won't worry too much

Also, it is worth thinking of upgrading to LCD. It's a proven fact that LCD monitors are better heath and safety wise. I have been using one for 4 years and symptoms such as eye strain and headaches are radically reduced do to being flicker free. CRT's also emit x-rays. which cant be good in the long run.

I won't go back to CRT now.

[drfsupercenter]

Well I have an LCD too. I will really not worry now.

you are a very smart man paglamon

LOL.Not really!!!Just happen 2 b an Ophthalmologist by profession.

Can prolonged monitor use cause astigmatism? I used to have 20/13 vision. Now I have an astigmatism and I have to blame it on Computer use.

[paglamon]

Can prolonged monitor use cause astigmatism?

No.Astigmatism i usually due to inequal curvatures of different axes of the cornea.

I used to have 20/13 vision

U mean 13/20 vision?That is NOT a very good vision.

[TNT]

Oops! 13/20; I could see at 20 what 'normal' people see at 13. Is that right?
What causes astigmatism?

[UncasMS]

with an eyesight like that you shouldnt point guns at other ppl any longer, tnt

*gg*

[TNT]

USED TO. Now I have 20/20. But have an astigmatism. I got glasses because they were like 20 bucks through my insurance, but I never use them because I heard wearing glasses makes the situation worse. It's not like I need them. I think the glasses correct me to 10/20 that I can (but don't) use for driving.

[drfsupercenter]

My vision is horrible, like 20/100 or the other way around... but 20/20 with my glasses.

[paglamon]

Oops! 13/20; I could see at 20 what 'normal' people see at 13. Is that right?

U got it all wrong.If ur vision is 13/20,it means u only see something from 13feet which a NORMAL person can see from 20 feet.So ,DRF(without his glasses)can see from 20 feet what I(with 20/20 vision) can see from 100 feet.
As to the cause of astigmatism:it is a structural defect of the eyeball where the front surface(usually the cornea)is NOT exactly spherical e.g the horizontal curvature may be more/less than the vertical curvature.This causes inequal refraction of light at the cornea and a perfect image cannot b formed on the retina.However astigmatism can also b caused in older ages due to lental changes like cataract.

There is a blindness inheritance in my family. My grandad went blind around 30, my brother is almost blind in one eye, and recently my eyes are getting worse, especially at night. Ill have to find out what its called, the condition. Its carried by females but affects males. I was tested for it as a kid, and told i didnt have it, but now im not so sure.
