Reading Glasses at the Screen: What Actually Helps

Anyone over 40 who wears reading glasses knows the problem: you sit down at your desk, put on your reading glasses, and something just feels off. The text is either blurry or you have to crane your neck into an awkward position to see clearly. What is behind this, and how can it be solved?

Why reading glasses are not ideal for screen work

Reading glasses are optimised for a reading distance of around 30 to 40 cm, which corresponds to the distance to a book or newspaper. A computer monitor, on the other hand, typically sits much further away: usually 50 to 80 cm from the eye.

This means: with standard reading glasses in front of a screen, you either see blurrily, or you have to move so close to the monitor that your posture and neck suffer. Neither is a good solution, especially when you spend several hours a day working at a screen.

Reading glasses, computer glasses, blue light filter: what is what?

Several terms circulate around the topic of glasses and screens, and they are easily confused:

Reading glasses: A single-vision lens designed for close range (30–40 cm). Ideal for books, newspapers, and smartphones, but not well suited for screen work.

Computer glasses / screen glasses / office glasses: Glasses specifically designed for the screen distance of 50–80 cm. They cover the near and intermediate range but not distance vision. Anyone wearing this type of glasses will see the background blurrily, as they are designed purely for the workplace.

Blue light filter glasses: Glasses with a special coating that filters short-wave blue light emitted by screens. They can be worn as reading glasses, computer glasses, or without any prescription at all. The filter reduces eye strain and can support better sleep, but it does not replace sharp vision at the correct distance.

Can you combine a reading glass with a blue light filter?

Yes, and for many people this is a practical solution. A reading glass with a blue light filter coating protects the eyes from screen radiation without the need for two separate pairs. It is not a perfect solution for the screen distance, but it noticeably helps during extended screen sessions.

Those who work a lot at the computer and primarily read at close range, meaning the monitor is positioned close to the desk, often get on well with this combination.

The 20-20-20 rule: simple relief for tired eyes

Regardless of which glasses you wear, your eyes need regular breaks during screen work. The 20-20-20 rule is a simple and effective approach:

Every 20 minutes, take a short break
For 20 seconds, look at something
that is at least 20 feet (around 6 metres) away

This allows the eye muscles to relax after being constantly tensed during near work. It sounds simple, but it reliably helps against tired, burning eyes at the end of the day.

Monitor positioning makes a real difference

Beyond glasses, monitor positioning plays an underestimated role. Recommendations from ergonomics experts:

Monitor at a distance of 50–80 cm from the eye
Top edge of the screen at or slightly below eye level
Screen tilted slightly backwards (10–15°)
No direct light source directly behind or in front of the screen

Following these guidelines significantly reduces eye strain, even without specialist screen glasses.

When does a dedicated computer glass make sense?

A dedicated office or computer glass is worth considering when:

you spend several hours a day in front of a screen
your standard reading glasses at the monitor cause headaches, neck tension, or blurred vision
you have no need for distance vision at your workstation

In certain circumstances, the cost of a screen workstation glass can be covered by your employer. Under workplace display screen regulations, an employer may be required to fund a medically prescribed computer glass where regular screen work and a demonstrable visual need are established.

Summary: the key points at a glance

Standard reading glasses are simply not designed for screen work — the distance does not match. Those who spend a lot of time at the computer should either consider a dedicated office glass or at minimum pay attention to correct monitor positioning. A reading glass with a blue light filter is a good compromise for anyone who does not want to manage two separate pairs.

Regular breaks, a well-positioned screen, and glasses that genuinely match your visual needs — together, these measures can significantly reduce most complaints associated with screen work.
