There is no scientific evidence that there is enough blue light from computers to cause harm to the eyes. Staring at computers can make the eyes dry. Every 20 minutes, look at a distant object 20 feet away for 20 seconds. This will relax the eyes.
There is no evidence that they help the eyes. I would recommend, if you have to look at a monitor most of the day or paper under fluorescent lighting, get pale yellow (night driving) lenses that clip on your regular spectacles, or if you don't wear spectacles in the office, get the pale yellow glasses in a sporting goods store (used for target shooting)- that will make your vision much more comfortable.
Not established yet. If you are more comfortable with them, by all means. SO
The data is not in. Please refer to this article from the American Macular Society:
Blue Light
The scientific evidence implicates blue light as a risk factor in contributing to the onset or progression of macular degeneration, as well as other eye diseases such as cataracts. However, the blue light emitted from the sun and the blue light emitted from electronic devices are significantly different. While most of the research agrees that UV blocking sunglasses are an important protective measure against sunlight exposure, the research on blue light emitted from electronic devices is contradictory and inconclusive. Studies such as this one
https://www.nature.com/articles/s41598-018-28254-8#Abs1 verify that blue light can cause damage at greater intensities, but the findings of such studies tend to get extrapolated by the press or marketing campaigns to implicate all blue light as damaging, including that emitted from electronic devices. However, this study, and others, did not show effects.

Blue light blockers work for reducing glare, but only in dim situations. They can be overwhelmed by strong sunlight. They are great in lower light to increase contrast and reduce glare. They are used by some baseball players on cloudy days to make it easier to see the ball against the white background.

Some intraocular implanted lenses use blue light blocking technology to reduce the harmful effects of blue light
Yes with computer work
They may help with computer related eye strain, but no research has been published.
They protect you from the deleterious effects of blue light, especially if you use a cellphone or computer at night, as it throws off your circadian rhythms through pathways connecting the retina to the pineal gland.
