Photoshop: How to set different opacity on image from 100% to 40%?

[Jenna5F85]

Hello,
i am newbie. I have spent one day searching for solution and find nothing working...
Maybe i am searching for wrong keywords. I am sorry if this is stupid question.

Problem:
Photoshop 2017 CC
I am trying to re-create lenses for sunglasses and then put it on face.
I have cut out lenses from frame, changed color of lenses.
The goal is to make lenses (100% opacity)
with opacity continuously decreasing verticaly from 100% (upper part) to 40% (bottom part),
so bottom part will be semi-transparent and little of face will be visible via lenses.
I can not find settings which allow this.
I am able to change opacity of lenses only for whole lenses, not able to set decreasing opacity.

Any simple solution?
Thank You a lot!
Jenna

Thank you for reply, but in your video i did not find where i can set opacity start at 100% and end with opacity at 40%.
Use a gradient tool and drag a line to side is lottery to set opacity from 100% to 40% and every time it is different...

Thank you very much for your reply.
Is it also possible to replace my black lenses with lenses which are already gradient (as on goal image - gradient from original image-not gradient created by me in PS)?
But how to add opacity continuously decreasing verticaly from 100% (upper part) to 40% (bottom part) - to those lenses from goal image?
Is it possible to set opacity from 100% to 40% also for cutted out gradient lenses (like on goal image) ?

my question in simple way:
is it possible to set to image gradient opacity which decrease verticaly from 100% (upper part) to 40% (bottom part) ?
Or is it possible to do only for solid colors my question in simple way:
is it possible to set to image gradient opacity which decrease verticaly from 100% (upper part) to 40% (bottom part) ?
Or is it possible to do only for solid colors which i filled part of image?which i filled part of image?

It is possible to decrease verticaly from 100% (upper part) to 40% (bottom part) ?

Take a look at screenshot below, click on right side Opacity Stop and set Opacity to 40%. Ensure that left side Opacity Stop is set to 100%.

Another option available to you is to use Gradient adjustment layer and to restrict gradient using layer mask.
