Look as far ahead as you can. (Ask instructor to get his damn chart out of your face if need be).
By looking at 'infinity', your eyes diverge so you gain peripheral vision.
When the runway edge 'touches' the bottom of your headset, start the flare. When it reaches the middle of your ears, you're down. (And as Strake says, works at night too.)
During the flare, NEVER pull back more than 1/2 inch in one go (and I emphasise
in one go - don't assume 1/2 inch will be enough).
If 1/2 inch not enough, pull back another 1/2 inch and repeat as necessary until your main wheels are down (I've had students get everything right to about 2 feet and decide they've done enough, then bounce).
If 1/2 inch too much, you may balloon but only very slightly, so wait for it to sink back down, then continue as before.
Sometimes you'll need several consecutive 1/2 inch pulls in quick succession, just a microsecond between each to assess. The best landings from the right approach you'll find you need about 4, a second or so apart.
While this is going on, point the aeroplane down the runway with your feet and keep it on the centre-line with aileron. (That's crosswinds sorted too then.)
Agree with other posts: Once on the ground (whether you slammed it in or greased it...), spend a few seconds looking at the end of the runway. This is what being on the ground looks like. You should find (as mentioned above) that the ground in your peripheral vision is around the middle of your ears.
As others have said, when I first learnt on grass, I was told to flare when I could see the blades of grass rather than just a mass of green. Caution: If your eyesight's less than perfect, guess this wont work. Get your medical before trying this method...
