First, try f.lux. It’s a software which includes Windows and Mac version both. It can change the laptop color automatically by the time of day, and make no-glare on your eyes.
If you stare at a computer/laptop screen for more than 2 hours, you have 90% chance to get CVS (computer vision syndrome). You eyes will get hurt. Only Flux is not enough to help you eyes. You need to find more tips. See the solution I gave to protect your eyes from your computer/laptop screen before:
Ideally more than 25 inches from eye and 6 inches below the horizontal eye level. Anti-glare screen Will decrease the amount of light reflected from the screen.
Use suspended lights from ceiling and windows with shades, blinds or curtains. Avoid light hitting directly on eyes.
Use chairs with armrests which are able to provide, support while typing, position of head slightly tilted downwards and height of the chair adjusted appropriately so that the feet reset flat on floor.
Follow the 20-20-20 rule, which means every 20 minutes, look away from the monitor, and focus on an object at least 20 feet away, for 20 seconds.
Choose your eyes and slowly roll your eyeballs clockwise and anticlockwise. Repeat it 3 times.
Blink frequently to keep the front surface of your eye moist.
To block the blue light, glare, and radiation when in computer and mobile device use. It works better than a monitor or screen protector.
As I suggest, a pair of computer glasses to block harmful lights can really be considered. I already chose one from tamieopt.com and it really comforts my eyes. You can get more choice from Gunnar and T'amie optics if you want.
