A coated article such as a mirror or window is provided, the coated article including a coating supported by a glass substrate. The coating may include at least a reflective layer in certain example embodiments of this invention. In certain example embodiments, the reflective layer and/or a layer proximate thereto is selectively oxidized or oxidized in areas corresponding to draw lines or other non-uniformities in the glass substrate. This permits reflections from the coated article to be more uniform and/or less distorted.

1. A method of making a mirror, the method comprising: providing a glass substrate;depositing a reflective layer comprising aluminum on the glass substrate;selectively oxidizing portions of the reflective layer comprising aluminum corresponding to undulations defined in each of the glass substrate and the reflective layer; andafter selectively oxidizing portions of the reflective layer comprising aluminum to form at least aluminum oxide, depositing one or more dielectric layers on the glass substrate over at least the reflective layer in making the mirror, wherein the mirror has a visible reflection of at least about 85%, and wherein the selective oxidation improves a uniformity of a visual appearance of the mirror. 2. The method of claim 1, wherein the reflective layer directly contacts the glass substrate. 3. The method of claim 1, further comprising, after selectively oxidizing portions of the reflective layer, depositing first and second dielectric layers on the glass substrate over at least the reflective layer. 4. The method of claim 1, wherein at least some of the selectively oxidized portions of the reflective layer extend downwardly into the reflective layer at least about 1 to 100 nm. 5. The method of claim 1, wherein the selectively oxidized portions of the reflective layer form a plurality of substantially parallel rows or columns in the mirror. 6. The method of claim 1, wherein the selectively oxidized portions are not continuous across the entire reflective layer of the mirror. 7. The method of claim 1, wherein the mirror is a first surface mirror. 8. A mirror comprising: a glass substrate;a reflective layer comprising aluminum on the glass substrate;wherein selective portions of the reflective layer are oxidized corresponding to undulations defined in the glass substrate, the selective portions comprising aluminum oxide; andat least one dielectric layer on the glass substrate over at least the reflective layer of the mirror, wherein the mirror has a visible reflection of at least about 85%, and wherein a visual appearance of the mirror appears more uniform after the selective oxidation. 9. The mirror of claim 8, further comprising at least one dielectric layer provided between the glass substrate and the reflective layer. 10. The mirror of claim 8, wherein at least some of the selectively oxidized portions of the reflective layer extend downwardly into the reflective layer at least about 1 to 100 nm. 11. The mirror of claim 8, wherein the selectively oxidized portions of the reflective layer form at least a plurality of substantially parallel rows or columns in the mirror. 12. The mirror of claim 8, wherein the selectively oxidized portions are not continuous across the entire reflective layer of the mirror. 13. A method of making a mirror, the method comprising: providing a glass substrate having undulations defined in at least one major surface thereof;depositing at least one layer comprising aluminum on the glass substrate so as to be substantially conformal to a surface of the glass substrate having the undulations; andselectively oxidizing portions of the layer based on locations of the undulations in making the mirror to form at least aluminum oxide, and wherein the mirror has a visible reflection of at least about 85%, wherein said selectively oxidizing is performed in order to improve a uniformity of a visual appearance of the mirror. 14. The method of claim 13, wherein the undulations comprise draw lines of the glass substrate. 15. A mirror comprising: a glass substrate having undulations defined in at least one major surface thereof;at least one layer on the glass substrate, the layer being substantially conformal to said at least one major surface of the glass substrate having the undulations;wherein portions of the layer are selectively oxidized based on locations of the undulations, and wherein the mirror has a visible reflection of at least about 85%;wherein the undulations comprise draw lines of the glass substrate, and wherein the undulations comprising the draw lines of the glass substrate are the portions that are selectively oxidized, and wherein the selective oxidation of the undulations causes a more uniform visual appearance of the mirror. 16. The mirror of claim 15, wherein the layer is one or more layers or a multi-layered coating provided on the glass substrate.
