YAY I’m learning smth!!

typical people having short sightedness – myopia.

people hving long-sightedness – hyperopia.

the one that older people have (lao hua yan)- presbyopia!

and LONG-SIGHTEDNESS is NOT equals to LAO HUA YAN! okay so now I don’t know what is long-sightedness and erm. whats the diff between presbyopia and hyperopia. I thought wear lao hua yan = long-sightedness? HAHAA. but I’m deemed wrong tdy by an optometrist-to-be. I realised I couldnt spell optometrist. I think the spelling is wrong!! hahaa.
