Clean Your Prescription Glasses in the Right Way
Prescription glasses are very expensive and they are also quite delicate. Once prescribed, you will be required to use the glasses while driving, watching TV, sewing or reading. Replacing glasses too often can be very expensive and so you cannot afford letting them get damaged. There is more to cleaning glasses than just wiping them with any cloth. There are many precautions that you should take when you clean them. The tips given below will help you keep your glasses clean.
Dry Cleaning Glasses Is Not Right
Most people clean their prescription glasses with only a cloth. However, this is not right. You should use a liquid of some sort like water or mild soap so that the dirt and grime on the surface can be cleaned properly. If you simply wipe them with a cloth or a tissue, this will only create more problems. The dirt present on the lens of the glasses can easily scratch it when you wipe them without using any liquid. Over time, this method of cleaning can cause a lot of damage to the lenses. To clean your glasses, simply run them under tap water gently and use a mild soap with hands. Rinse out the soap and pat it dry. Do not rub the lenses dry because there still could be some grime or dirt left on the surface. Use lint free, soft cloth for drying the glasses.

How Can I Order Prescription Glasses Online?
Prescription glasses have traditionally been a very expensive commodity to buy. Unfortunately, for many of us (myself included), it is necessary to buy them in order to correct our vision and thus lead normal lives. The good news is, however, that it is now very easy to order prescription glasses online. Let me explain how.
In the old days, we used to trudge off to the opticians and have our eyes tested. Typically our National Health Service or private health insurance scheme would pay for all or most of this cost. That part was never that expensive anyway. But once the eye test was complete, many of us need then to organise a pair of glasses for us to see properly again (or replace our existing pair because our prescription has changed slightly).
The next stage is that we have the task or trying on frames to find ones that suit us. For me, and I would imagine a lot of people, we find the frame we like, only to find out they are far too expensive for our budgets, because guess what, our lovely governments generally don’t pick up the tab for our eye correction! Not stupid are they?
So, generally, we get priced out of the glasses that we really like because the frames are so expensive. Frustrating, especially when you can buy a nice pair of ‘sunnies’, for less than $50, and let’s face it, the frame materials aren’t too dissimilar!
However, our lovely new technology, computers, capitalism and Read the rest of this entry »
