We need to stretch/compress our eye to see far/near object<br />2) People with short sighted have a upper limit to their focal length<br />3) People with far sighted have a lower limit to their focal length<br />4) Old people can have both upper/lower limit to their focal length and hence need bifocal lens<br /><br />Thanks,<br />TKAnonymousnoreply@blogger.com
