1.5 vs 1.6 lenses which is better?

[Tyndall]

Does anyone can tell me what the difference between 1.5 lenses and 1.6 lenses is? And which one is better? Thank you in advance!

1.6 lenses are suggested for prescriptions of +/- 3.00. It is said that 1.6 lenses are 25% thinner than standard plastic lenses so that they are ideal for higher prescriptions. Compared with the 1.5 lenses, 1.6 lenses are thinner and they can work well with thinner metal frames so they will look better. Besides, they are very light.

What are your degrees in both of your eyes? I have +2.0 in both of my eyes. So usually I will choose the standard plastic lenses. But if you have high prescriptions, the 1.6 lenses are good for you because the edge of this kind of lenses will be thinner and they are very light so that they will not put heavy burden on your nose.

1.5 lenses are the standard lenses while higher index such as 1.6 works best for high prescriptions because this kind of lenses are thinner, lighter and can make people feel more comfortable.
