9 ways to protect your eyes from blue light

1. Use blue light filter software

For people who need to use the computer for a long time every day, using blue light filter software is a very good choice.

CareUEyes is an excellent comprehensive eye protection software that filters blue light by adjusting the color temperature. The lower the color temperature, the less blue light emitted by the screen.

In addition, CareUEyes also has the function of adjusting screen brightness and timing lock screen reminder to rest. For those with poor self-control and unable to rest on time, they can use the forced rest mode to rest.

CareUEyes has 8 preset modes, allowing you to quickly find the screen color temperature and brightness that suits you. You can also modify the preset modes and customize your own mode.

2. Reduce eye use time and take regular rest

If we stare at the mobile phone and computer for more than ten hours a day, our eyes will suffer long-term damage from high-energy blue light radiation.

After using your eyes for a period of time, you can blink your eyes or rest your eyes more to reduce the time of eye use. The most useful at the moment is the 20-20-20 rule.

For every 20 minutes of using the screen, you should try to move your sight 20 feet away from you for a total of 20 seconds. You might say, how can I tell where is 20 feet? Actually, you don’t need to be so precise. You just need to look far away as much as possible, such as looking at the scenery outside the window, walking in the office corridor, or standing up and stretching, looking at the distance and then pour a glass of water.

Regular rest can provide your body with agility and improve work efficiency. The eye care software CareUEyes can simplify these steps. It allows you to perform these steps more easily without stress

3. Wear anti-blue glasses

The anti-blue lens has a special coating to filter some blue light. One advantage of blue light glasses is that they can also filter the blue light emitted by the sun, TV and LED lights.


4. Replace LED lights with incandescent lamps

Led lights emit a lot of blue light. It is recommended to use incandescent lamps because incandescent lamps do not flicker and there is very little blue light in the spectrum.


5. Use screen filters

Screen filters can be used on most models of laptops, tablets and mobile phones. These filters can be easily installed on the device without damaging the original manufacturer’s screen or interfering with touch sensitivity. If your child uses a computer to play games or do homework, these functions are particularly useful, because, without supervision, the child is less likely to wear blue-light blocking glasses, but it is not portable enough and more expensive, different manufacturers’ Screen filters will also have varying degrees of quality differences

6. Do not try to use the device directly before going to bed

Excessive exposure to blue light can cause restlessness and insomnia. Set a limit to turn off the device at least one hour before bedtime and charge the device in another room so that you don’t try to turn it back on.


7.Intraocular lens (IOL)

After cataract surgery, the cloudy lens will be replaced with an intraocular lens (IOL). The lens naturally protects the eye from almost all ultraviolet light and some blue light. There are types of IOL that can protect the eye and retina from blue light.


8. Eye nutrition

By eating foods or supplements rich in key nutrients, you can support the natural protection of your eyes. Lutein and zeaxanthin are naturally found in foods such as spinach, kale and other green leafy vegetables. Nutritional supplements can also be used to ensure adequate daily intake.

Michael A. Smith, MD, said: “Natural retinal antioxidants such as lutein and zeaxanthin cannot regenerate fast enough to keep up with the harmful blue light that destroys the surrounding environment.” “We all quickly become deficient in lutein. . And because blue light-emitting devices are useless, the risk of macular degeneration is also increasing. Daily supplementation of lutein and zeaxanthin must maintain macular pigment density.”


9. Check your eyes regularly

The optometrist recommends that people in their 40s have an eye exam every two years and discuss with an eye care professional about the choice of ways to protect their family and eyes from blue light
