Good day Nairalanders This is a copy of a thread i did but was in the wrong section. I don't want to waste your time so am going to go straight. I do Jobs that allows me to stay up on my laptop for hours... and each time i do, i notice after about 2 hours, i get weak and my eyes becomes weak with a light head ache. that would make me stop. have adjusted all i need to adjust on my laptop but its still same thing. But i can't stay off cause that's my job. I met a friend who told me about Computer Glasses. I made research about it and i think its a good idea but the problem is i don't know where to get one and i want to know if it has any side effects. am currently in port harcourt. Please anyone with an idea of where to get one and what it will cost or a better solution to this screen problem? Thanks.... You can reach me via Nuel.impact@gmail.com
