Ain't that the truth.
In 1991 (I think) I had the displeasure of T-boning a Holden Commodore (me, open road; him, ignored Stop sign) on my XJ900, flying over the roof and landing head first on the road on the other side. Upon waking (20 mins later) I couldn't understand why my vision was so poor until a kind lady pointed out that the broken and twisted remains of my glasses had caused some facial trauma and she'd removed them to prevent further injury.
Yamaha, helmet, and Holden all written off; me, got better.
The Safety glasses I wear are actually designed to take a frontal impact ... and sit in contact with my face all the way around the rear edge of the glasses.
I've seen the result of a rider going through road works with the visor up (at relatively low speed) and get a stone in the face from a passing (speeding) car. He was lucky to keep his eye.

Must admit I wear safety squints, too. They work. Quite a few rocks have been deflected off them when I ride off road with the roostafarians.
As for the visor / sun strike / visibility discussion, my Givi Tourer helmet has a peak and internal sun visor. Covers all eventuality's really well. No buffeting at, er, higher speeds either.
Manopausal.
Although my Helmet isn't a budget model ... (or top of the line for that matter) I have put a strip of heavy black tape across the top of the visor. By tilting the head forward a bit ... it gives a bit of shade for the eyes. However ... Coming down a hill into a low sun can negate your efforts to get that "shade" ... and you can find yourself riding blind. Not a pleasant feeling at all.

Both, as you would expect or hope.
I do not like the open face or Jet type of helmet, I have fallen over in the past onto the road and its quite abrasive (surprise)
Not sure if HJC are DOT Certified or ECE.22.06 incoming standard - see below
https://ultimatemotorcycling.com/202...-set-for-2023/
amazing how in the USA of all places the DOT Certified doesn't mean much
from the above web page, with a little formatting to highlight the relevant parts - not that anyone will read it, like I did.
P) Full face: Helmet with a detachable, movable, or integral (permanently fixed) part of the helmet covering the lower part of the face and intended to protect the chin
(P/J) Modular Helmet: means a helmet, equipped with a movable or detachable protective lower face cover, that meets the requirements for both conditions of use with or without chin guard in position. Chin protection is only guaranteed with the lower face cover in position. In modular helmets, the retention system tests must be done in J and P configuration.
The regulation (Sec. 6.17) addresses the function of integral or internal sun shields:
“A sun shield shall not restrain or prevent the movement of the visor. On opening the visor, the sun shield can pivot in the working position. By means of a simple movement, the sun shield shall be able to be moved separately from the visor out of the visual field.”
In addition, the sun shield, whether externally or internally mounted cannot restrict the field of vision to less than the required 105° of peripheral vision, 7° upward field of view from horizontal and 45° downward, must transmit 80 percent of visible light and must be optically clear and correct.
The regulation addresses the issue of “conspicuity” or how visible the helmet is to other drivers in both daylight and low light situations.
That portion of the reg (Sec. 6.18) deals with the use of retroreflective materials on the helmet, which may be either standard factory-applied or provided with the helmet and applied by the end-user.
That part of the regulation is up to the jurisdiction adopting ECE 22.06 as to whether this provision is applicable.
If the jurisdiction elects to use the provision, the reflective material must cover at least 18 cm2.
The external face shield or visor must be able to withstand the impact of a steel ball of 6 mm diameter and 0.86g traveling at 60 meters per second (M/sec) without the impactor punching through, shattering, or dislodging the shield.
Provisions are also included to define the maximum and the minimum light transmittance of a visor capable of two different levels, as photochromic, liquid crystal, or equivalent visors.
The regulation also deals with the “anti-fog” properties of the external face shield providing an objective standard by which to quantify whether the face shield is truly “anti-fog” or not saying: “The internal face of the visor is regarded as having a mist retardant facility if the square of the specular transmittance has not fallen below 80 percent of the initial value without misting within 20 seconds.”
Helmets with accessories are tested to assure the equipment has no adverse effect on performance and that the helmet and/or visor still meets the applicable requirements. Testing is done with and without the accessory in place to assess any effect on energy absorption, presence of sharp edges, and alteration to the field of vision. For testing, accessories are fitted according to the helmet manufacturer’s specifications. Approval is valid only for accessories in use during certification testing.
A number of the requirements in the current ECE 22.05 standard are retained. For example, there may be no projections from the helmet surface that exceed 2.0 mm; impact attenuation peak acceleration is specified as a maximum of ≤275g (≤2,400 head injury criteria or HIC) for the standard linear impact and high energy impact test (≤2,880 HIC) and ≤180g (≤1,300 HIC) for the low energy impact test. Impact tests shall have a minimum headform velocity of 8.5 M/sec.
Tests for rotational (oblique impact) forces and abrasion resistance remain unchanged. Impact point specifications and helmet environmental conditioning criteria remain the same as do tests for strength, abrasion, and stretch of the chin strap retention system.

DOT doesn't actually certify anything, the helmet manufacturers self certify to the FMVSS standard and label the helmets as "DOT certified".
The National Highway Transport Safety Administration (NHTSA), which is part of DOT, enforces the standard by having independent labs test helmets to ensure they actually meet FMVSS 218.
And this is an improvement to the previous system??? I'd look for a Snell sticker if I was buying a helmet in the US.
