  • Is it good for adults to wear contact lenses?

    According to a survey, 26% of adults wear contact lenses in a certain place and we select two of them at random. Provided that at least 1 of them wears contact lenses. Can you count the probability that both of these adults wear contact lenses? So do you think is it good to wear contact lenses?

    Here we can count: 26/100 * 26/100 = 0.0676 So there is 6.76% of adults that both will wear contacts. It just depends on personal preference. Some like wearing contacts because they want to make their eyes stand out. Some best contacts have good quality and you can wear them safely.

      Almost everyone can wear contacts.But children and older people should consider some special conditions if they wear contacts.So for adults,it is good to wear contacts if you take good care of them. It is more convenient to wear contacts.
