How to protect your eyes from laptop screen glares.
There are various ways to protect your eyes from laptop screen glares regardless of where you are using your laptop which may be outdoor or indoor. These ways are not very expensive or difficult, and they are highly beneficial to you. They are as follows;
- Try using anti-glare glasses (for those who use glasses) or anti-glare screens.
Anti-glare screens have improved visual clarity. They reduce eye strain and also lessen blue light exposure.
The anti-glare screens diffuse the excess bright light from the screen and reduce screen glare, which causes serious eye problems.
Although the anti-glare screens diffuse light. However, it does not diffuse all of the bright light on the laptop screen.
- Adjust your laptop position, if it’s in front of an open window, or door or if you are working with it outdoors, under no shade. Or if you are working with it when you are directly under a light source (light bulb, lamp) indoors.
Why it’s advisable to always tilt or swivel your laptop from direct lights, or to go under a shade if you are working outside, it’s so that the bright light does not reflect on your screen while you are working, because it could cause eye strain.
Note: curtains can also be used to cover the bright light sources. For example; Windows, and doors.
- Try to wear dark shades of clothing if you are working outdoors with your laptop, although it might be uncomfortable especially if it’s a sunny day.
But it’s advisable to wear dark shades of clothing because they don’t reflect light the way light-shaded clothes reflect light. Light shades of clothing reflect light that hits them pretty bad.
- Another way to protect your eyes from laptop screen glares is by making them brighter. Sounds counterintuitive I know. But, hear me out.
By making it brighter, you attack the light reflecting on your laptop screen by the laptop’s own light.
Though this method is not really efficient, as it doesn’t stop the glare entirely, it however makes it easier to see what you are working on, without you squinting.
- Try to adjust the color temperature of your laptop to make it less blue.
Blue light from laptop screens, damages rods, and cones in the eyes affecting the night vision and color vision abilities of the eyes. Blue light also causes eye strain.
In order to protect your eyes, always ensure you adjust the color temperature of your laptop to make it less blue because it prevents eye strain.
- Try not to forget about protecting your eyes internally, as you are protecting them externally.
Protecting your eyes internally involves the intake of vegetables and foods that are nutritious for the eyes.
Nutrients like lutein and zeaxanthin found in foods like parsley, and green peas which are plant nutrients, help in reducing eye strains from laptop screen glares. It is advisable to consume foods rich in these nutrients regularly.
- Always try to take frequent breaks, when working on your laptop. In order to prevent eye strains, and protect the eyes, it is advisable to always take breaks while working on a laptop.
It is advisable to stare away from your laptop screen for twenty seconds, after every twenty minutes, because doing this protects the eye.
The Human eye is vitally important, and it is advisable to protect them from harmful lights, like the laptop screen glare.
