Study Notes
Preventing Eyestrain when Looking at a Computer Screen
- Follow the 20-20-20 rule: every 20 minutes, look away from the screen and focus on something 20 feet away for 20 seconds.
- Take a break every 45-60 minutes to stretch, move around, and rest your eyes.
- Place the computer screen at a distance of 20-25 inches from the eyes.
- Position the computer screen directly in front of the user, and at a slight angle to reduce glare.
- Place the screen slightly below eye level to reduce strain on the neck and eyes.
Lighting and Screen Settings
- Adjust the room lighting to be softer than the screen, as bright lighting can cause eyestrain.
- Use a dark background with light-colored text, or a light background with dark-colored text for eye comfort.
- Avoid using a pure white or bright background, as it can cause eye strain.
Screen Time and Phishing Attacks
- Reducing screen time can lead to a decline in myopia (nearsightedness) in children.
- The primary difference between an email in a spear phishing attack and an email in a phishing attack is that spear phishing attacks target a specific individual or group, while phishing attacks target a wider audience.
