Depending on the amount of glare in the image, one approach which can work well is to use the Pro tab > Burn tool to paint over the glasses a few times. You can try doing it with “Highlights”, “Midtones” and “Shadows” selected in the tool’s options. I have found that using all 3 can create a realistic edit. Also, painting the same spot a number of times increases the intensity of the tool.
Another suggestion I have is that on our Design Corner group on Facebook (for Premium members) there are many users who are keen to share tips such as this and it’s a good place to ask for help (there are also members of our team on there fielding questions where helpful).
If you have any other questions, please let us know!
