So, let me see if I have this straight.

Anti-glare coating keeps light out and decreases the brightness of,
say, a computer monitor.
Anti-glare coating can be purchased in cheap, clip-on form.

Anti-reflection coating allows more light to come in. Thus, if I am
wearing glasses with anti-reflection coating, my glasses reflect less
light towards the people who are looking at me.
So, if I am sitting at a computer, anti-reflection coating will make
the monitor appear brighter than it already appears?

Also, the lenses that I buy will be transition lenses. That is, when
the sun goes up, the glasses become sunglasses. So, on a sunny day, is
anti-glare coating necessary if I have transition lenses? And, as for
anti-reflection coating, will transition lenses and the anti-reflection
coating cancel each other out?

Thanks.

Antiglare lenses have a polarized coating on them that ideally cuts out a
bit more than half of the light. In addition, it cuts out some reflected
light off of the pavement near what is the Brewster angle. Look that up in
Wikipedia. I personally use CHEAP clip-on polarized glasses for that
purpose.

Antireflection coatings on glasses are nice but usually not durable. They
are anti-FLARE as opposed to anti-GLARE. That is, the typically 4% of light
at a lens air surface is reduced to about 1%. This lets more light get
through and reduces the multiple reflections that might be annoying.

I find antireflection coatings to be more useful in cameras where the stray
light can leave a permanent reminder on the picture. For spectacles, you can
often, but not always, move your head in a way to minimize the annoyance.

Hello. I am a 33-year-old male.

I need to get a pair of glasses with the prescription -5.00, -5.00 for
driving, watching movies in a theater, etc. Would it be useful to buy
lenses that have anti-glare or anti-reflective coating on them?

What exactly does this coating do?

Also, I may buy another pair of glasses to use as reading glasses.
These glasses would be used for reading, computer use, etc. Would
anti-glare or anti-reflective coating be useful for these glasses?

I have had driving glasses and reading glasses before, and I don't
think I've ever had anti-glare coating before. I'm not sure, but I
don't think that not having this coating has been a problem.

The coating can cost as much as an extra $75 for each pair of glasses.
So, is the coating worth the price?

Thanks for any information.
