The average cost of new lenses (without frame and eye exam) was over $225.00 in 2012. If your frames are titanium frames the final cost will be even higher. There is a good chance that the cost of your repair will be a fraction of the cost of new frame/lens.
Most lenses sold today will have added coatings which add to the final cost of the product. Scratch coating, anti-reflective coating and higher quality lenses can add up. This is why you should consider having your frames repaired by ALL American Eyeglass Repair who is accepting mail-in repairs from around the world and has convenient eyeglass frame service centers.
