My eyesight took a crazy dump about 5 years ago. Wild because I used to have eagle vision but .. getting old is not for the weak.
So ... sights. I frigin love the TFO sights from Truglo but they dont have them for the CZ Compact. I had them on 5 different Xd's and they were wonderful.
Reading the hype I bought the TFX for a 1911 I have that had black front blade and black rear. The blackouts were great as the front blade was narrow enough to allow you to pick it up quickly and center it naturally but were kind of useless in diminished light.
Put the TFX on and HATED them. I was a truglo fan but these sights had a much smaller aperture to allow light to the tube so they became sucky to me in all light conditions. They were more money than the TFO and someone wrote great copy for them but in my opinion were not nearly as good as the TFO's I had used before. Off they went and I put the black back on. $130.00 in the garbage.
Now on to the CZ. The sights it came with were useless to me and I now have trouble with 3 dot sights. Just becomes a big white fuzz. I put a Hi Viz brand front on and took a marker and blacked out the rear white dots. Happy day !!!
I can very quickly and intuitively shoot my compact in anything but black out conditions and I dont live in a place without ambient light and don't intend to shoot at things I cant see so its not a problem.
There are plenty of front Fibers out there but the light tubes on the Hi Viz are crazy easy to replace if damaged and they come with a kind of cage that helps prevent damage in the first place. Many of the fiber front sights I see are naked and thus prone to more damage.
Tritium is great only in the dark .. otherwise it is just a regular not so great sight set. Think about your needs. My front sight still gets plenty of light even at night in my home with ambient light but in medium and low light they really shine and the tritium would be worthless. Here are some pix

My kit came with a tool for changing out light tubes and it came with a green, red and opaque white tube. The tube is a nice large circumference dot and easy for me to pick up.
Of course YMMV
