Materials For Prescription Glasses

March 2nd, 2016 No comments

It is a known fact that online stores for prescription glasses offer a diverse range of prescription and designer eyewear. Not only the designs but also the colours vary widely, giving you countless options to choose from. While choosing prescription glasses, their one aspect which should be given due attention is the material of which the frame is made of. The durability and the finishing of the prescription glasses depend a lot on the material of construction and the two most commonly used materials are plastic and metal.

Prescription glasses with plastic frames are generally light-weight and offer a comfortable eye-wear experience. In fact, laminated plastic frames with layered colours are a widely popular option. When light colours are used on the interior sides, your prescription glasses become less visible. Likewise, an all–black frame is visible at all times on both the interior and exterior sides.

Among the variety of plastics used for prescription glasses, most manufacturers use cellulose acetate propionate. It is a nylon-based plastic which is light-weight and offers more transparency and gloss than other plastics. When compared to metallic frames, prescription glasses made of plastic have better exposure to sunlight.

When it comes to durability, prescription glasses with metallic frames have been a perennial favourite. So much so, that the most widely used material in the manufacture of prescription glasses is “monel”, a mixture of broad range of metals. Its malleability and corrosion resistance give the prescription glasses a gloss and longevity of the highest quality.Though considered a PART of metal family, titanium frames come with the added advantage of being light-weight. It is a silver grey metal that’s durable, strong and corrosion–resistant.

Care And Cleaning Of Your Prescription Glasses

December 3rd, 2015 No comments

No matter how much you are careful while handling your prescription glasses, the need for cleaning and reglazing always arises. The cause may be dirt on the lenses, scratches or misalignment of the arms. A Basic Knowledge regarding these, like simple polishing techniques and adjusting the arms tricks will help you to take care of the “minor” problems and to take the right decisions.

FIRST of all, one must take every effort to reduce the chances of scratch or a twist on the arms. One should never leave the prescription glasses face down, as it increases the chances of the lenses getting scratched. Both while putting on the prescription glasses and taking them off, you need to make sure that you pay extra attention, because even the slightest pressure on one of the sides may result in a misalignment. This misalignment, however small, will cause discomfort which will only increase with the passage of time. These STEPS mentioned not only increase the longevity and usefulness of the pairs, but also save money.

When it comes to cleaning the lenses of your prescription glasses, it will be always better to FIRST rinse them with water. This will remove the smallest particles from the lenses. This is an important STEP, because without following it, any attempt to wipe the lenses will inevitably lead to scratches. You can also purchase lens cleaner from optical stores which will help you to take care of the scratches. Usually, the cleaner is poured on the scratch and a soft cotton cloth is used to rub that liquid. In fact, even baby oil is known to be used as a lens cleaner.

In case you have found out that your prescription glasses are running asymmetric, chances are one of the arms or both of them are twisted. If the twist is a minor one, you can try applying some pressure on it to make it straight again. But this should always be done, by keeping the prescription glasses on a soft surface, else scratches will occur. In the unfortunate situation of your lenses coming out, one should never try to solve the matter at home, as only a trained optician would be able to do that.

One must always remember to put the prescription glasses in the case, when not in use. Though it sounds obvious, keeping the prescription glasses in the open is one of the most Common Causes of scratch and misalignment of frames.
