In the past, people who have very bad vision sight have to wear glasses with very thick lenses, which is not very good. With so heavy glasses every day, pressure on our nose is heavy. And after some time, our eyes will be transformed and look unnatural. Mordern glasses don’t have this problem.
The lenses helped people a lot in the past but there is a problem that the lenses are thicker and heavier due to higher prescription, so some people don't like them. Nowadays, with the help of modern high index materials, people can enjoy good vision together with comforts and improvements in their appearance with thinner and lighter lenses.
The lenses of modern glasses are not only lighter, but also have different coatings available, so as to reduce reflections and increase anti-scratching ability. And there is a kind of lenses developed recently called transition or photo chromatic lenses. The advantage of this lens is it can darken the light and change light conditions; of course, it is also in light weight. For people who like to take some sports, or need to work under tough conditions, for example, working with machines, there are specialized prescription lenses available to offer us good vision and protection as well.
Generally speaking, there are a wide range of modern glasses available on the market to meet people's increasing needs for spectacles. For people with nearsightedness or farsightedness, they can choose single vision lenses with the majority made of plastic. Bifocal lenses enable people with both nearsightedness and farsightedness to see clearly as there are two separate zones, the upper one is for farsightedness, and lower zone for nearsightedness. Varifocal or progressive lenses can help people to see all distances clearly without noticing distinct division as it has a gradual change from far distance to near.

After the test and analysis, your eye doctor will advise which one is the most suitable for you.
