At ozoptical.com, all standard lenses are made of lightweight CR39-resin with a standard lens index of 1.499, coming with a completely scratch resistant coating. Polycarbonate lenses are the lightest material available (optional), and due to its high impact-resistance and durability, it also happens to be an integral material used in making bullet-proof “glass”.
Prescription eyeglasses for my kid
My son is only eleven years old but he has been troubled with poor eyesight problem for a long time. I am not contented with his bad habit of taking an incorrect reading position as soon as he tends to do some reading. To buy a suitable pair of prescription eyeglasses places much pressure on me because my husband is so busying with his work and he does not have any time to concern about such trifles. I try my best to deal with this challenge well. But since none of our family members need to wear eyeglasses, I have no related experience. In order to gain a better understanding of kid’s prescription eyeglasses including style, function, safety and price, I decide to visit local optical shops first. I never know that eyeglasses at present are so expensive, especially for those with famous-brands that can be even called an article of luxury. In my family, only my husband is the bread winner and I have to save money as a qualified housewife. So, I don’t think that I can afford one pair from real stores. |
