1. Sensitive to light

    There are some common reasons that people are sensitive to light, for example, conjunctivitis, keratitis, dry eye, and eye strain. When bacteria invade the eyes, the eyes are prone to foreign body sensations, redness, and photophobia. When the corneal part of the eye is inflamed, it is prone to increased secretions, photophobia, and eye grinding. People with dry eyes are prone to photophobia, redness, and tears when rubbing their eyes with their hands. If the eyes are used excessively for a long time, the eyes are in a state of fatigue, and the eyes will also be sensitive to light. 

    If you do not know why you are sensitive to light, you’d better go to the hospital and have an eye check. Wearing blue light blocking glasses can reduce the syndrome if it is caused by dry eye and eye strain.

2. Digital eye strain

    Digital eye strain is a symptom of eye discomfort after prolonged use of electronic devices, such as dry eyes, blurred vision, fatigue, as well as neck and shoulder cramps, headaches, etc. The main symptoms are eye fatigue and blurred vision. People who work in an office with computer screens suffer digital eye strain easily. Short-wave blue light refracted from screens such as computers and TVs is one of the major causes of digital eye strain. Short-wave blue light has relatively high energy, which will increase the number of toxins in the macular area of the eye, causing the retinal pigment epithelial cells to die, thereby causing vision damage. And blue light blocking glasses can filter most short-wave blue light and reduce harm to the eyes.

3. Poor sleep

    Short-wave blue light will inhibit the secretion of melatonin, making it difficult to fall asleep. That is because a ganglion cell protein called melanopsin (also known as melanin) is present in our retinas. The protein responds to the intensity of light, especially blue light of shorter wavelengths, and thus inhibits melatonin secretion of hormones. If you are hard to fall asleep, try to reduce the time to use phones or computers before bed. It is also a good idea to wear blue light blocking glasses when using digital products before sleep.

    Besides wearing blue light blocking glasses, good habits also help protect the eyes. For example, use 20-20-20 rules. Take a 20-second break after 20 minutes of using an electronic device, then look 20 feet away. Eating various fruits and vegetables and supplementation with lutein and fish oil are also good ways. They have an amount of omega-3, which can protect macular photoreceptor cells.

    In a word, if your eyes are sensitive or always have to expose to blue light for a long time. You can consider having blue light blocking glasses on Eyekeeper!
