Contact Lens Material - Hydrogels
The raw material of the hydrogel is called HEMA. HEMA is hydrophilic and has a water content of 38% by itself. By cross-linking with other polymers, the water content can be up to 80%. The world's first soft cloaking material (OttoWichterle, 1961) was made from HEMA, called PHEMA. Nowadays, most conventional hydrogels are made up of the copolymer of PHEMA and other monomers.
Why do you need rimless glasses?
Traditional full-frame glasses can sometimes make your face look heavy, especially if the lenses are thicker. Rimless glasses can replace heavy frames without weight from the rims. This reduces the pressure on the nose pad, making your face feel lighter and more comfortable.

Bifocal lenses have two observation areas separated by visible lines, a larger observation distance area, and a smaller reading area. It may take some time for people who are wearing bifocal glasses for the first time to get used to the lenses. This is mainly due to learning how to move the eyes between the observation distance area and the reading area. Some people will also find that there will be an 'image jump' phenomenon at the visible line between the distance and the reading area, especially for those with limited mobility, who must look down when walking. The best way to get used to bifocals is to wear them as much as possible.
