Light transmission and tint-color?

[Knipan]

Hi all.
Need your advice/input.

Yesterday’s shooting got me thinking, or more trying to understand what happened.
Shot a 2x50 comp with lunch break in between. Started out fine the first round shooting 32/50 which for me I a good result. Second round, couldn’t get my shooting together at all, ending up at 21/50.

What I was thinking, it started out bright and a bit sun, so decided using my CMD lenses (RE Falcon Pro) which are quite dark a LT of 18%. After lunch, cloudier and less light, but didn’t think of changing lenses. It felt like I couldn’t find the clays, seeing them late and hard to keep focus.

But, what I’m wondering, could the lens tint have that much of an effect om my result?

Also, wondering how you all think regarding light transmission, as right as possible or as “dark” as possible?

Thanks!

You've answered your own question really - you couldn't seem to see them, picked them up later and couldn't focus.  Some will say its all hype particularly when you get into all the different lenses Pilla do for example but I for one use different lenses for different situations.  As you would imagine, overcast, grey, dark skies - I have lenses that let more light in and various colours for different backgrounds to help me pick up the clays.  Bright sun, targets in sun - dark brown lens which still helps me pick up my worse colour - orange.  Sometimes I even revert to my old oakley clear lens.    I need all the help I can get to see the bar stewards  particularly the colour ones.

The basic thing to remember is don't choose lenses in the same way you choose sunglasses. Don't do as dark as 18% unless you are welding. Those are to take all the strain away and relax you. Shooting glasses are usually less dark. My basic rule is as long as you aren't squinting, they are dark enough.

Was fideling with lenses according to light conditions for some time, untill it dawned on me I am "light numb" and almost always grasp for every lux I can get - even at bright sun. From then on 65% max orange lens are permanent.

It is difficult to know what to do for the best results but when it gets darker you generally want a lens that lets more light through. I use RE Rangers and usually use the Dark Purple for all conditions but I am getting a set of the light purple for those days when it is just a bit darker. That way I hope to get the benefit of the colour contrast I want but still get enough light to properly see the target.

Shooting glasses are primarily for colour filtering to enhance clarity and/or contrast depending on the colour of the clay and the background. Glare reduction can be partly achieved with darker lenses but the colour is still the most important thing. The primary function of sunglasses is to look cool, but it's generally better for your eye muscles to adjust to varying light levels naturally than to wear dark glasses.

I find leaving them on all day helps allot - it may seem stupid but my eyes tend to take a while to adjust when i have sun glasses - Shooting glasses on so i keep them on all day, i use a light shaded pair of polarised sunglasses with a orange tint - they are amazing for shooting as they really do make the clay darker against the sky. also if you are worrying about the glasses in the back of you mind this is only going to affect your aim when shooting.

When you got the Ranger 18% lenses, can I ask what you did with the white stick  ?  I have a friend who needs one  !

Well it's a different topic but the less you wear sunglasses the better it is for your eye health. The adjustment to varying light levels is performed by special muscles and like all muscles they benefit from exercise and thus the better they work and the faster eyes adjust. Our eyes are perfectly capable of handling all but the most extreme natural light/dark transitions.

Thanks to all.

A lot of good information, and once again I realize I had the wrong approach to this   

It's as light as possible and not as dark as possible...

By the way you owe me a new IPad, as minne nog is drenched in coffee... 

Well you learn as long as you live  :baby:

Thanks to all.

You'd better hang onto that stick then  !

PS  There was an ad for Lab pups in the clubhouse yesterday  ???

FWIW - my scores improved significantly when I ditched all the fancy colours and went to clear lenses in all conditions.

As said earlier your eyes are good at accommodating an infinite variety of conditions, that's what they were made for!

Thats an interesting perspective...please elaborate?

That's a strange question from an eye specialist. I don't know what I can add. Muscles that are under used will atrophy and since the size of the pupil is adjusted by muscles in response to changes in light intensity, they - and by extension eye health  due to increased circulation - benefit from being used as nature intended. Much like any other muscles in the body.

but I don't want to frazzle my eye balls by looking anywhere near the sun.  Also I find I am quite sensitive to light and screw up my face even on a dull day when the sky is grey/white I sometimes find that hurts my eyes.

Yes, the pupil size is adjusted by the two groups of muscles, the sphincter pupillae and the dilator pupillae. Average pupil sizes go from 2 to 8mm and as you say respond to light levels. However, the judicious use of sunglasses will not have a detrimental effect on the efficacy of these in the same way that living underground in the darkness would.

The circulation comment i do not understand.

The positive effects of wearing appropriate UV protection far outweigh any light sensitivity issues. These include cataract, macular degeneration, photokeratitis and skin cancer so sunspec use is important for maintaining ocular health rather than the contrary.

For lots of people, they can also alleviate visual stress caused by too much light getting into the eye so the old adage of "wear the palest lenses or clear because thats what nature intended" doesnt hold water.

For some folk this can be all they need, others should wear what suits the individual.

The circulation comment i do not understand.

Exercising muscles increases circulation because of the need for extra oxygen by those muscles and surrounding tissues. If that didn't happen all forms of exercise would be pointless. As for the need for UV protection I don't have any clinical studies either way, but statistics indicate that the prevalence of cataracts in Europe and America is very much higher than Africa, which seems strange...

 

[EdLyons]

I think we're on tenous ground suggesting that occasional sunspec use has a negative effect on ocular circulation...

Cataract is the leading cause of sight loss in Africa. Unfortunately, there is a marked difference in the African population's access to ophthalmic care than in Europe and the USA so the number of Africans per capita undergoing cataract surgery will be less than ourselves.

Are you suggesting that there is no need for UV protection?

 

[Westward]

Vision is not my area of expertise but as someone with a lifetime's interest in matters of health, fitness and well being I read many reports of health and medicine related surveys published by serious organisations. Some months ago, one such report compared cataract prevalence and compared Africa with the US/Europe. Of course I realise that in the west we have better & earlier diagnosis and the probability that lifespan is much less in Africa, nevertheless the result was something that should be of concern to all because the raw stats showed that Americans were 26 times as likely to develop cataracts as Africans.

I haven't suggested that occasional sunspec us has a negative effect on ocular circulation any more than I would suggest that sitting down to eat has a negative effect on lower leg circulation. My objective was to suggest that over use does. Many people reach for the sunglasses the moment there's any brightness and I believe that has a negative effect on ocular circulation just as sitting at a desk all day has a negative effect on lower leg circulation.

I'm not commenting on my beliefs about UV protection.
