Product Q&A

Q:Is it true that avoiding glasses will worsen myopia?
A:
Absolutely, refraining from wearing glasses can strain your eyes further, potentially exacerbating myopia.
Q:Can myopia be cured?
A:
Unfortunately, myopia cannot be reversed. It's caused by the elongation of the eye axis, similar to height, which is irreversible.
Q:Will wearing glasses affect our children's growth in height?
A:
As children grow, various factors come into play, with reading being a significant one. Equipping them with the proper eyewear can play a crucial role in decelerating the advancement of myopia, ensuring healthier visual development.
Q:If my vision remains clear, is there a need to wear glasses?
A:
Glasses serve an essential purpose in delicately maintaining the balance between eye accommodation and convergence. This balance is vital in preventing visual fatigue from escalating and averting any undesirable changes in eye alignment, ultimately safeguarding your vision.
Q:Is it essential to wear glasses continuously, or can they be worn intermittently?
A:
For individuals whose physical development is complete and who experience minimal eye strain, wearing glasses with a prescription of less than 200 degrees is advisable primarily during prolonged distance or close-up tasks. However, if you are still in the growth phase or experience significant eye strain, resulting in rapid fatigue and a prescription over 200 degrees, it is recommended to wear glasses consistently to protect your vision.
