1.Prevents Eye Strain
Blue-light glasses can be one way to ease digital eye strain in either case. This specialized eyewear filters blue light and increases contrast, allowing you to focus more easily and preventing eye strain. Get computer protective glasses with yellow lenses if you wish to enjoy viewing digital devices for long periods. However, various factors can lead to eye strain, so it is always advisable to seek medical/optical advice whenever possible.
2. Reduces Your Eye Disease Risk
Too much exposure to blue light can increase your chance of developing eye diseases such as cataracts. The blue light can penetrate through the cornea and then reach the retina.
Indeed, it is true that your cornea and eye lens can block harmful UV light from reaching your retina, but they cannot block blue light. So, wearing blue light glasses can reduce the detrimental effects of constant exposure to blue light, which will reduce your risk of getting eye diseases.
3. Provides Better Sleep
Blue light can negatively affect your normal waking and sleeping cycles and the quality of your sleep. Moreover, blue light in the evening can hinder your body’s ability to produce melatonin.
Besides affecting your body’s production of melatonin, blue light also disturbs your natural body clock. You may find it difficult to sleep at night and get up in the morning if your brain associates blue light with daytime. Likewise, you can minimize this effect by avoiding screen time 30 minutes before sleeping. As an alternative, putting blue light glasses on before sleeping while using your smartphone can also help mitigate the effects of blue light exposure.
