Use a set of quality set of blue light blocking glasses:
for daytime use we recommend the ScreenTime Premium Day Glasses. These glasses use our ClearBlue Lens technology which blocks all the harmful range of blue light responsible for eye damage and eye strain, without distorting the colour you see - perfect for people who are using computers or other digital devices during the day.
For nighttime use we recommend our range of blue light blocking glasses. Our blue blocking glasses are specially designed and manufactured to remove 100% of blue light. These are the prefect blue light blocking glasses for watching movies at night, working on computers/tablets after sunset, or using other digital devices just before bedtime.
20-20-20 Rule - after every 20 minutes of looking at a digital device, take a break for at least 20 seconds and look at something approx 20 metres away. This has been shown to significantly reduce eye strain caused by prolonged exposure to electronic devices, and even during the day minimise the damage that is being done to your overall eye health.
Position your computer screen approx 25 inches from your face and angle the monitor about 10 - 15 degrees below eye level
