Answers
Explanation:
1 we can't see it because our pupils takes time to expand because in movie hall it contains less amount of light so our eyes need more light to see the objects so after sometime we are able to see seats or steps
2 we have to wear the helmet because while skating if we lost our friction we can fall so for our safety we have to wear it
Answer:
1) no we are able to see as light is availible there.outside the cinema hall there may be more light as compared to hall,so pupil of our eye gets little smaller, but when we enter cinema ,our pupil takes little time to get larger, so that's why for a little time we are unable to see anything .
2)when it comes to safety , you should be wearing a helmet whenever you are skateboarding.The very purpose of it is to protect your head from severe injury in case of a fall. Concussions and a variety of head injuries happen, especially when you're a beginner.
3) They protect your eyes from saltwater and chlorine;they provide greater clarity and they can be designed with prescription lenses to suit your needs.
