Advances in Eyeglass Lenses
<p>Perhaps another reason for the enduring popularity of eyeglasses can be found in new lens designs, which help eyes to see better or appear more attractive even when stronger are needed.</p>
<p>Because these new types of lenses are thinner, the old days of thick, Coke bottle style glasses have virtually disappeared.
Among the most popular types of eyeglasses lenses prescribed today are:
Aspheric lenses, which are not perfectly rounded on the surface, recently have been designed as a way to correct for small distortions in vision that can be associated with more traditional eyeglasses lenses. These types of designs also make lenses thinner and lighter.
High-index materials also are associated with thinner, lighter lenses, because of the more efficient way this special plastic refracts light to help you achieve focus. Because less plastic is needed with high-index materials, eyeglasses lens thickness is reduced.

didnt the club send the email? it's the one with the one where the hong kong university wanted to have an internation competition or something... I heard from my friend in hong kong that the people going to that university has to join a sports club in order to be able to stay at the uni dorms. And they get pranks pulled on them if they miss training...

You're on the wrong board, Pak. Post it on the other one.
Do it.
Do it now.
Do it.

Only then will I post a suitably witty reply.
