It is recommended that you consult with an ophthalmologist or certified optometrist in an optician's shop to see if it is appropriate for you to wear contact lenses. If there are contact lenses suitable for you to wear, please note that serious myopia (above 600 degrees) will certainly increase the lens thickness , thus the recommended time to wear glasses every day is less than 8 hours.
They can wear contact lenses! The degrees of contact lens are different, generally the highest degree can reach 1000, if your myopia degree is more than 1000, you can also choose to customize the lenses that are suitable for you.
It is ok to wear contact lens, but I suggest you should go to regular hospital to undertake optometry first, which will be safer, however you'd better wear frame glasses in daily life. I also suggest you not to wear contact lenses for a long time that will make the eyes dry, easy to cause inflammation, such as keratitis. You are advised to keep your eyes moist and not overdo it.
