For many years, people have been using eye glasses for vision correction. The lens in your eyeglasses brings clarity as well as safety to your eyes. Traditionally, eyeglasses were available in the form of pince-nez, monocle, scissor glasses and lorgnette but the latest designs include nose and temple padding for greater comfort.
Along with the style, there has been a change in the materials used for making eyeglasses. While glass is still used, new synthetic materials like plastic, CR-39 and polycarbonate have been incorporated to increase the durability and ease-of-use for eyeglasses. These materials also offer protection for the eyes against harmful UV rays, fix higher eye abnormalities and transmit light in a much better way than glass lenses.
Scratch resistance and anti-reflective coating are also new features of modern eyeglasses. These are very effective for glare reduction and improved night vision. Buying hydrophobic glasses allows you to resist dirt and water barring your vision and makes it easier to clean your eyeglasses.
Before you buy any particular eyeglasses, ask your optometrist or doctor for advice. The purpose of eyeglasses is to correct vision by combining the lenses in glasses with your eye lenses. Usually, vision problems like farsightedness, astigmatism and nearsightedness require prescription glasses.
On the other hand, safety eyeglasses may be needed to shield the eyes from chemicals, flying debris or other dangerous materials. People working in laboratories or heavy equipment industries must wear eyeglasses to safeguard their eyes from hazardous exposure.
While eye glasses for vision correction are highly recommendable, it is also important to buy good sunglasses to protect the eyes against UV rays. These may be prescriptive or non prescriptive. In recent times, photo chromatic lenses are being used in eyeglasses to serve the dual purpose of vision correction as well as keeping out the sun.
