My modular has a clear shield and a dark drop down fighter pilot shade. I don't like the shield down much and almost always ride with sunglasses on and shield up. I need reading glasses(getting old sucks) so I wear safety sunglasses with readers built in....they cost about $10, so when they get all scratched up I throw them away and put on a new pair:

My fav are the Elvex Sonoma's....good wrap around coverage for riding & there is always a new pair stashed in my . For night & rain I have a pair of clear bifocals I wear even when the clear shield is down so I can see my instruments.

I get caught out at night too often and like the wind on my face so I run a clear shield that is only down for weather and bugs, use sunglasses during the day, and clear safety glasses at night. If I'm going for more than an hour or so, and for sure on all day or multi day rides I wear polarized glasses. There are lots of documented cons to polarized glasses on motorcycles, but none of them weigh heavily for me. I prefer the polarization because it really reduces eye fatigue for me, allowing me to ride longer and safer.

Two strips of electrical tape across the top of my visor helps tremendously. Allows me to tilt my head slightly and block the early morning / late afternoon sun. I also wear prescription sunglasses.

All great comments, Like many of you have posted this requires we get "Creative" when it comes to vision
before during and after the ride. Clearly, it's not a one size fits all world when it comes to Seeing where your going.

I need glasses for driving only, So I keep a pair of Prescription clear lense glasses ,and a pair of prescription sunglasses
at the ready, I have my Clear HJC visor (in storage ) and opted for the $45 Mirror tint visor when I purchased the
full face helmet. Turns out to be money very well spent. With the mirror visor and my regular glasses on- fit and function
is great no issues. On real bright outdoor conditions (Florida) I can swap for the sunglasses under the visor. These glasses
are a little bigger than the clear ones but still work fine. Some times I need to lift the visor completely up and ride with
just the glasses for protection. (when it's really hot out) Those sunglasses were purchased at America's Best Vision center
and ran about $200 with the motorcycle frames. I've had them 2 years and they still work just fine.
I also have a police style Peanut helmet But I do not wear it hardly at all because it won't work well with the ear plugs.

My HJC modular has the internal dropdown sunshade, which I love. Since I have a Givi windscreen, I'll ride with the visor up and the sunshade down quite comfortably.

I have prescription Rayban sunglasses, bifocal. My distance vision is adequate but I have trouble reading the gauges, gps, phone screen with just sunglasses. Polarized are out for me. In addition to causing problems with reading electronic screens, I can't see into the windshields of modern UV-protective glass on automobiles. I'm looking for the eyes and faces of oncoming traffic to try and determine what the driver is/isn't looking at. Polarized lenses render oncoming windshields nothing more than a blur of clouds with no indication of what is behind the windshield.

I have been using a Pinlock photochromatic face shield overlay for about two months now. It is a light sensitive film sandwiched between two semi-flexible polycarbonate sheets and attaches to the outside of their proprietary shields using their Pinlock system. The overlay locks down on the shield with no fluttering or blister effect. It changes from 100% clear to a reasonably darknened bluish grey tint in a very short time. Not as dark as some smoke shields but ideal for my type of riding in wooded valleys and open farmland high country. Optically pure with no distortion and absolutely clear for night riding, and no glare or sprites from oncoming headlights. Easily unmounts for cleaning or for rain riding. Although it does have a silicone bead around its perimeter, water can get caught between the shield and the overlay.
It is the best solution for bright sunlight I have ever found. https://pinlock.com/products/overlay/

I heard of a hack for riding into low angle sunlight but I haven't tried it yet: Carry a roll of 1" blue painter's tape to stick on your face shield or windshield in a way that blocks the sun from your field of view. You can still see over and under it taped to the shield for reading the road and traffic signage, but the sun will be blocked most of the time. When the sun goes down, peel it off easily for night riding.

Very well said Scab, I read you loud and clear. You must be looking for what the drivers are looking at --- if it's not you
then there's a problem.

I used to wear generic plastic motorcycle glasses behind my HJC clear pinlock.
Now that i bought the HJC dark smoke pinlock, i ditched the glasses, and get way less fog (i nevr inserted the pinlock shield).

My bike has a dark smoke windshield too, no issues about seeing the road at night.

Prescription glasses, sunglasses for me...Zenni Optical dot com has every style imaginable and they are around $20 a pair...shipped

I keep a spare pair of glasses, sunglasses, and readers stashed on the bike. Never know when a pair will wind up broken or missing.

Have had Ray-Ban's, Serhengetti's, Oakley's, Smith and a half dozen other brands through the years...polarized through a Pinloc makes for some trippy riding! Prefer the amber-colored lenses for most riding/driving but yellow tint is awesome for cloudy days with flat light.

Also have used tri-focal (progressive), bi-focal and single-focus lenses...preference for now is narrow enough lenses to look under for gauges, etc. although the need for readers gets more apparent as time marches forward. YMMV
