1, put polarizer as the standard. Projector is different cheap oakleys polarization as the standard is slightly different. There are two transverse polarization as the standard, a row of polarization axis 135 degrees (or 45 degrees), the next row of 45 degrees (or 135 degrees). Some two

Polarization as the standard in a row without polarization folder as the standard, a total of three rows.

2, the eyes have been fine-tuned pre-corrective lenses. Try in the right front of the lens increases the polarization P, axis at 135 degrees (or 45); left front plus polarizer P, axis 45 (or 135). Two polarization test through the fake oakley sunglasses lens while, Watching standard polarization concept. At this point, the right eye to see is a row of polarization as the standard, the next row of the left eye is seen as the standard.

3, asking patients to compare two rows of polarization as the standard, which discharge clear.

4, the patient may have three different answers. a, two rows of the same polarization as the standard definition or equivalent fuzzy. Shows two have been adjusted balance. b, upper row, as the standard, please Xi, the next row of fuzzy. Does not meet the description of two Balance, be in the right front increase +0.25 DS, up and down the same row as the standard definition. c, as the standard fuzzy upper and fake oakleys lower rows of clear. Increase in the right front of +0.25 DS, until the bottom two rows so clear.

5, if the two can never be the same clear or vague. To do the inspection on the dominant eye to maintain dominant eye vision slightly better than the non-dominant eye.

6, the end point of balance between his eyes checked. Eyes mpmva and color tests.

7 Note: (ibid.).

Method 3: two-color polarization method

1, put polarization color as the standard.

Polarization as the standard two-color red, two green blocks, within each Ma has a black color digital video standard: 9,6,3,5. Of which 9 (green), 6 (red), with 135 degrees (or 45) polarization; 3 (green Color), 5 (red), 45 degrees (or 135) polarization.

2, right eye front 135 degrees (or 45) polarizer, put the left front of 45 degrees (or 135) polarizer. At this point, two red and green simultaneously see four Ma polarization as the standard (Figure 3 left). Right eye can see is the green block 9, as the standard word

And red 6 as the standard (Figure 3 middle). 3 left to see is a horizontal green and red 5 as the standard.

1, two-color polarization while watching cheap oakley sunglasses as the standard, no fog. There may be several situations:

a, four-color visual target polarization

Exactly the same brightness and clarity, shows two have balance. b, Green 3, and 6-color bright red, increase in the left front of +0.25 DS, up to four color luminance equal, binocular balance. c, Green 9, 5 red lights in the right

Immediate increase +0.25 DS, until four color so bright and so clear, color balance. If you can not balance, to maintain the dominant eye corrected visual acuity slightly better than the non-dominant eye.

2, if the single-color light, indicating the precise stage of unilateral mistake. 9 such as green light, indicating that the right eye overcorrection of myopia, hyperopia low coercivity.

6 bright red color, indicating the low myopia cheap oakleys correction for the right eye, hyperopia overcorrection; 3 bright green for the left eye myopia or hyperopia overcorrection low coercivity; 5 bright red, indicating that the left eye myopia or hyperopia overcorrection low coercivity. Need to re-do mpmva monocular

And color tests.

3, eyes foggy concept. Before the eyes of the Canadian +1.00 DS, remove the polarization color as the standard, for the vision statement, two of the decreasing +0.25 D, do mpmva. Back to color as the standard, until the red and green light are equal.
