lumens versus eye age

from my own observations i expect that there is a curve that fits to
lumens needed and eye age


hopefully lumens needed levels off and we do not take down the local
power grid turning on the lights

or we just cannot see enough to work wood and call it quits


this is where the talking shop tools come into play


am still thinking about the talking table saw fence and might not be
hard to do


i know there is a blind guy or gal that does wood working

re: Restaurant lights

While I agree that reading a menu in low light can be an issue, I do like
the ambiance of *eating* in low light. For me, it keeps the outside world
out, even if that outside world is only a few feet away. The time spent
perusing the menu is probably shorter than every other "activity" involved
with a dinner out.

May I suggest these? Wearable and standable.

IDK but seems unbalanced IMHO.

>bright lights make people leave sooner

I disagree, depending on the business.

One of the first things I will comment on in a restaurant is the poor
lighting. How the hell do you expect us to read a menu in the dark?
Ergo... the flashlight on my phone comes out, I comment to the wait
staff and or management, then I either leave or never return.

My 2 Cents.

SWMBO and I were walking the dog around dusk a few weeks ago. As we walked past
a house with open windows we heard a female voice. "Oh my God! Oh my God! Ohhhh
myyyy Goddddd!"

We figured she was getting in an early evening prayer.

There is but it's probably not what you think it is. Generally, the
older you are the lower the range of focus (presbyopia). A more
intense light causes the pupil to constrict, which increases the depth
of field - you don't have to focus as closely/accurately/at-all to see
clearly. Of course, cataracts will cut down on the light entering the
eye, as well. AIUI, from cataract patients, modern cataract surgery
fixes both problems.

How about one of the Wixey digital fences? I have one and like it,
except the head has a lifespan of about a year. :-(

Right. Some restaurants are designed to be bright and loud to turn
tables. Others, for ambiance. The two models have a different
cost/price structure.

A professor of mine used to do remodel consulting and he would comment
how many (commercial) customers would request more lighting. There are
standards for Lumen levels depending on the business (banks are quite
high). He said that more often than not. the lighting fixture density
was up to spec, it just was the tubes and light diffusers were very
dusty. I know when I clean my fixtures/bulbs every few years, the light
in the shop seems much brighter. Dust gets _everywhere_! You may not
want to hear it, but after a sanding session, I can use nose buggers as
spackle and get a perfect color match. 8^)

I've "discovered" the concept of task lighting to help my eyes. Some
well placed spot lighting on the TS, router, and other saws really helps.

Yes, when lighting is subdued, people tend to be more subdued too and
talk a bit quieter.

Of course total darkness changes that. I hear peoplel screaming "oh
god, oh god, don't stop"

The dim lighting in a restaurant tends to keep the noise level down too.
