There is always a strong temptation to buy cheap eyeglasses because the prices charged are so abysmally low. Titanium is a high quality material that is also tough and light in weight. You can also tell a good quality eyeglass from a cheap one by checking the material of the lens.
If the lens is made from polycarbonate then you are assured of good quality. You can also identify a pair of high quality eyeglasses by checking the coating of the lens. Similarly, lenses with scratch resistant coating or anti-fog coating are also indicative of high quality lenses.
