Common sense of purchase
1. The main function of anti-blue light glasses is to reduce the damage caused by harmful blue light to the photoreceptor cells on the retina of the fundus to a certain extent, and cannot fundamentally prevent myopia.
2. Children wearing anti-blue light glasses should be used under the guidance of an ophthalmologist or optometrist. When purchasing, pay attention to whether the product name, factory name, and factory address are complete, and ask for and save the purchase certificate.
3. High blocking rate anti-blue light lenses with a yellowish color may cause color shift and aggravate visual fatigue. If necessary, it is recommended to buy anti-blue light glasses products without color shift. According to the actual situation of exposure to blue light, it is reasonable to choose anti-blue light lenses, not lenses with a lower blue light transmittance ratio are more suitable.
Use common sense
1. It is not recommended for children to wear anti-blue light glasses for a long time in daily life. Children's eyes are still in the developmental stage, and wearing blue light blocking glasses for a long time may have an impact on eye development.
2. Parents should pay more attention to children's eye hygiene and use their eyes reasonably. For example, rationally plan the use time of electronic products for online learning, adjust the brightness of electronic products to avoid too bright or too dark, place electronic products away from direct light, adopt correct reading and writing posture and maintain a proper viewing distance, etc.
3. Reduce screen time outside of online learning and increase outdoor activity and rest time to help relax eye muscles and relieve eye fatigue.
