Why do we use antibiotics eye drops rather than tablets in case of any problem?
Q. Why do we use antibiotics eye drops rather than tablets in case of any problem?
A. When you can’t distinguish one colour from another one than you have colour blindness. A very simple test is done to know whether you are suffering from it or not. There is a set of cards with scattered coloured dot over the page. One has to detect certain patterns among the dots. If he does so, then he is fine otherwise he has the problem. It is hereditary and is carried by X-chromosome.
