Alternate distance and near exercises, let your eyes zoom in and out repeatedly to exercise your eyes' ability to adjust focus, for one minute each time. 4.

Eye exercises: Keep your head still and look up at the ceiling, then return to the upright position and scan the far point image, then look left, right and down respectively, and each time you return to the upright position, scan the far point image.

• 【Optical massage relaxation】Use precise and clear far point images to guide the eyes to actively relax the eye muscles and release intraocular pressure. When you are tired, the eyes can see the distant images gradually and clearly in ten seconds.
• 【Alternate distance and near exercise】Adjust the focus from the near point to the far point, and then adjust to the near point, repeat the exercise until the eyes feel that the letters in the distance are getting clearer and the switching speed is obviously faster
• 【The principle of far-sightedness】Gradually look at the farther distance from the letter A, and when it reaches the far point, look at the square points on both sides of the letter, let the eyes repeatedly move back and forth between the letter and the square point, and deeply relax the eyes
• 【Image rear light】9-level brightness adjustment of the backlight. RA90 has a color temperature of 4300K, the light is natural and soft, and the image is clear and comfortable for the eyes. Let the eyes naturally enter a relaxed state
• 【Applicable to most people】Different people use different letters for exercise and relaxation. The red square dot next to the letter can help confirm whether you can see the distance clearly
