Photochromic and Anti-Reflective Windshield for Drivers

avatar

Greetings to all and sundry,

I do hope that we are all doing amazing and having a wonderful time, today is Friday and I believe I speak for the majority of us if not all of us that we are grateful the weekend is here, there's a big opportunity for us to rest and recuperate as we wait of the busy schedule of the days ahead.

I am here today once again and for those of you who are quite familiar with my blog you know I am here to talk about things concerning our eyes and our health, today I would not be talking about a condition but rather a theory I have which I seek to solicit your thoughts and ideas as to the feasibility and how many would actually be willing to try things out if given the opportunity. I do hope you enjoy the read as usual.


Introduction


Most of us are familiar with the photochromic lenses that optometrists and Opticians dispense for patients to protect the eyes from UV as well as make it more tolerable to walk through the sun on a sunny day or tolerate more extreme light.

Most often whenever we prescribe the photochromic tint we tend to add something we call anti-reflective coating to it, what this coating does is absorb the rays that come from objects so that our lenses don't end up reflecting images again, this feature is very helpful because without it wearing lenses would have been extremely uncomfortable and many would have experienced haloes in their vision.

Also, the anti-reflective coating makes it much safer and more comfortable to drive in the evening or in dim light, this is because light from oncoming traffic does not end up bouncing back and scattering up, which would have worsened the already bad vision in the evening due to inadequate light in the environment and may have likely led to accidents occurring quite often.

And so it is actually recommended that drivers especially those that end up traveling late in the evenings and at night, both commercial and private vehicle drivers wear anti-reflective lenses to make driving more comfortable for them, I have lots of patients who use their lenses only for driving and many continue to testify during review periods about the benefits they get when driving.


The Theory


And so it came to me in the past few days when I was reading an article on night driving by JANESSA AMY KIM LIN with the title Night driving and assessment of mesopic vision for older adults and I was wondering why car manufacturers haven't come out with the technology of anti-reflective windshields yet.

By the way, when we talk of mesopic vision we refer to the type of vision where the rods and the cones of the eye are stimulated due to the environment having both substantial amounts of light and darkness, similar to what happens during twilight. Now I know it is recommended that we all see our Optometrist for photo anti-reflective lenses for protection and comfort when driving both day and night.

But what if we actually had our windshields having these tints in them then the comfort will not only be for the driver wearing the lens but all members in the car, we get to have more eyes seeing comfortably on the road such that they could even draw the attention of the driver if they also see something on the road.

In addition to this, the field of safe vision, let me put it that way, is enhanced, and if your windshield comes with the bonus of photochromic tint or coating them on a sunny day you do not have to quint to drive because your windshield will adjust automatically making it quite comfortable for you to drive safely.

I do drive and so I believe I can relate to some of these issues however I started not so long ago, my license is quite new and so I wanted to know the thoughts of the members of our community if they believe this is feasible and that scientist trying this would actually benefit the majority. I know for patients with mature cataracts the photochromic shield may damp their vision which could make driving unsafe for them however aside from this is there anything else that comes to mind when you think of this theory?

I would really love to hear your thoughts, I know @apineda would have interesting things to share about this and I would very much love to hear what @lemouth thinks about this too. Let me use this opportunity to also invite @mcsamm, @depressedfuckup, and @collinz so that would let me know their thoughts on this too.


Conclusion


I know we didn't talk about a particular condition today however I would love to wrap this up by reminding us to be particular about our sight and our ocular health, let's avoid over-the-counter medication, let's have regular reviews and examinations, let's inform others and share the knowledge we acquire about our eyes through these writeups.

Remember that your eyes are the window to the scenery of this world and that early detection not only saves sight but also saves lives. Many thanks to you my dear reader for your time, I very much appreciate you. Be safe and I wish you a wonderful weekend. Ciao.

I personally have anti-reflective lenses for many many years. They are so comfortable...:D

For vehicles, I think most modern cars have anti-reflective windshields. At least this is confirmed by this source, although I am unsure it is a very valid one. However, what they wrote makes sense to me. I currently don't have time to look for better references online. Maybe will you find some?

Just read the article you shared, I think he is also making assumptions much like the theory I had in mind, for now what he seem certain of is the fact that dashboards are made to be anti-reflective so they don’t end up disturbing view from the wind shield. Also, modern cars been manufactured seem to have anti-reflective properties unlike the old types however there are still lot of issues that manufacturers are facing and have to deal with along the line some of which could possibly involve legalities.

But I’m optimistic that with where the world is headed in terms of tech soon all car manufacturers would consider this and perhaps even add photochromic coating like I was suggesting, It would be a beautiful drive when that finally happens.

I’m glad to know you are using AR lenses though, I use one myself and I always prefer to have it one when I’m driving late in the evening, is very comfortable and I recommend it to my patients all the time.

PS: Don’t forget yournext review appointment with your optometrist though, I said I would remind you so this is me reminding you😅😊

I don't remember when I switched to those. Maybe when I was a teenager (I am wearing spectacles since I was 6 or 7)? Who knows... What is clear is that there is no coming back ;)

Lol... in 23 months ;)
