Eye protection lamp and sunlight, under which light is it better for children to write homework?

Of course, it is an eye-protection lamp, and you can often see "don't read in the sun", and the eye-protection lamp is of course more eye-friendly.

Of course, it is an eye protection lamp, because the eye protection lamp on the market is very complete in functions, and it can also protect eyesight to a certain extent, and the light is relatively soft.

No matter how the lamp is placed, the light comes from a certain direction. What we have to do is make the light emitted a little less harmful to the eyes.

Most people write with their right hand, so much so that our right, right front, and right back are blocked by arms, hands, and pens. If you put the lamp on the right, there will be a shadow on the words we write.

When reading a book, the brightness requirement is 500lx, but if the book is dark all around, only the brightness of the book is 500lx, which is not good for the eyes - no matter how focused people are, they can't keep staring at the same place. If the brightness of the book is too different from the surrounding environment, it will cause frequent pupil contraction and dilation, which in turn will cause visual fatigue.

As a general rule, the brightness of the environment around the table should not be less than 300 lx – if there is no way, you can choose to dim the lamp or remove it to reduce the difference in brightness.

First of all, in the choice of table lamp, be sure to choose an eye-protecting table lamp to protect your eyes!

Choose a table lamp for your child. In terms of style, try to choose simple and generous. The color list should not be too flashy. Desk lamps that are too ornate and decorated distract children and are not conducive to learning.

There are two ways for manufacturers to meet the requirements of the national standard: one is to increase the frequency of flashing, so that the eyes cannot "feel" the flash; The second is to convert alternating current into direct current, because the strobe is caused by current fluctuations, and direct current does not fluctuate.

If a light has an AC-to-DC unit, it is certainly not a strobe.

If there is no cross-turn, you can use your phone's camera to point it at a light source. If streaks or changes in light and dark are observed in the light source, there will be a strobe flash, otherwise it will not. This method is less accurate, at least it can weed out a large number of low-quality goods.

It should be the light that shines from the front oblique top that is the most eye-friendly, because this will allow the child to clearly see the words on the homework.

The light from the top is more eye-friendly, and the oblique light will cause damage to the vision and the lining of the corner of the eye for a long time, so it is best to irradiate directly above.

Shine in from an oblique top that does not hurt the child's eyes and illuminates the textbook.

Cataract is caused by cloudy lens, and exposure to ultraviolet rays (sunlight contains ultraviolet rays) is one of the causes of acquired cataracts, which are relatively slow and require long-term accumulation.

The characteristic of this type of eye-protection lamp is that it does not feel flickering through a high-frequency electric board. In addition, natural light is restored by energy-saving lamps in three primary colors. Choose according to the frequency of the table lamp:

Generally, the eye-protecting desk lamp requires more than 40,000 lighting frequencies per second to ensure the continuous and stable light to high-frequency flashing, rather than copying no strobe, such a desk lamp is more suitable for students to use.

Vision Trainer Light Recently, a new concept lamp has aroused the interest of experts and scholars. Thermal radiation light source is a kind of incoherent light source, which is a light source that converts heat energy into light energy in the state of thermal equilibrium of a luminous object, such as incandescent lamp, tungsten halogen lamp, etc.
