Polycarbonate lens material is lightweight and thin, making it cosmetically appealing to many people. These lenses are especially recommended for the following people:
Children: Since polycarbonate lenses are shatter-proof, a child's eyes won't be damaged by shards of flying glass or plastic if the glasses are hit hard by a ball or a bat.
Monocular patients: People who only have one eye or who have decreased vision or blindness in one eye -- called monocular vision -- should wear a polycarbonate lens. Because monocular patients are using only one eye for vision, it is imperative that they do everything they can to protect their best-seeing eye.
Industrial workers: People involved in occupations that have a high risk of injury must take extra precautions to protect their eyes.
Athletes: Those participating in high-impact sports should regularly wear safety lenses to protect their eyes from injury.
First of all, mix up the warm water, several drops of mild liquid detergent and 1 tsp. of baking soda in a bowl or basin. Then swirl them untill they become soapy. Second, dampen a microfiber cloth in the mixture and use the cloth to wipe the eyeglass frame and nose pads. Then apply a cotton swab which is dampened in the mixture to wipe inside and around the lenses to clean them completely. Finally, rinse your eyeglasses in warm water and gently dry them with a soft cloth or a special eyeglass-cleaning cloth. Hope this helps you.

Actually, conjunctivitis is most commonly caused by viral infection. However, bacterial infections, allergies, other irritants and dryness also cause its occurrence. Pink eye means some bacteria and viruses can spread easily from person to person, but is not a serious health risk if diagnosed promptly. Here we classify pink eye as viral infection and bacteria infection. Viral conjunctivitis is due to adenovirus, which is the most common cause of viral conjunctivitis. The most common causes of acute bacterial conjunctivitis are staphylococcus aureus, streptococcus pneumonia, and haemophilus influenza. Although pink eye can be fine in seven days with out any medical treatment, you still need to pay attention to it in that pink eye is the basic factor to cause other eye problems. And pink eye will spread person to person, so in order to spread it to others and get worse, you'd stay at home.
UV rays is very harmful for human health. We both know that too much exposure to UV rays would burn our skin and accelerate the aging process of skin, resulted in spots, wrinkles and even skin cancer. We always wear sun screen to protect our skin. However it is hard for us to realise the damages to eyes from UV rays. UV rays could also burn the surficial tissue of eyes, causing pain, sensitivity to light and discomforts. The best way to protect eyes from UV rays is wearing good sun glasses which can provide 100% protection. The night blindness refers very poor vision in evening or dim circumstances. It is usually caused by vitamin A deficiency, pigmentary degeneration of retina or poor development of rods cells in eyes. You'd better have a check to find out the cause.

If you want to save money, I suggest you to buy a pair of new glasses online. Usually the same glasses sold online are much cheaper than that sold in the physical shops. I have a pair of glasses which has been used for more than 3 years. Now I want to buy a pair of new glasses too. So I took my old glasses to an optician. He told me that I'd better buy a pair of new frames for the old frame was out of shape. So I doubt whether your frame has the same problem. Hope this is useful!
