Color-changing myopia lenses can not only correct myopia, but also reduce the exposure of ultraviolet rays to the eyes when you go out, but the ability to resist ultraviolet rays is limited and the color of the lenses is slow to change, so that patients may experience blurred vision and other discomforts. 1. Advantages: Color changing myopia lenses can protect the eyes, reduce the stimulation of ultraviolet rays on the eyes to reduce squinting under bright light, thus slowing down the production of eye wrinkles. Color change myopia glasses are more convenient to use, people with myopia don’t need to carry two pairs of glasses when they go out. 2. Disadvantage: The light transmission rate of color change myopia glasses lenses is low, so you may not be able to see clearly in a dim environment. If the patient suddenly enters a dark environment after wearing color change myopia glasses, the glasses will not be able to change color fast enough, which may cause transient blurring of vision. In addition to this, long-term use of color-changing myopia glasses may also lead to a decrease in the patient’s eye’s own ability to adapt to bright light. It is recommended that patients who experience discomfort after wearing eyeglasses should seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
