If you have recently undergone an eye test and been told that you need spectacles, you may be worried about having to wear spectacles. Some of this worry may be due to fears about how your spectacles will look and feel when you wear them. However, modern spectacles have benefited from technological advances and new designs. Read on to find out everything you need to know.
Many people who are diagnosed with an eye condition which requires spectacles worry about having to buy several pairs so they can read books and also perform tasks which require them to look a long distance ahead. Whereas in the past, you would need to purchase a set of reading glasses and a set of distance glasses, now you can invest in varifocal lenses. The prescription of each lens changes very gradually from the top (which provides focus at a distance) to the bottom (which provides near focus). This means you can wear the same set of glasses for activities which require different types of vision.
Traditionally, lenses were made of glass. However, glass lenses could feel heavy. However, modern spectacles are often fitted with polycarbonate or plastic lenses. These are much lighter than glass and this makes wearing spectacles much easier. While in the past plastic lenses did not produce such a clear focus, improved production techniques mean that these types of lenses now offer the same quality of vision as a glass lens. Plastic and polycarbonate lenses are also shatter-resistant.
Polarised and photochromic lenses
Australia is lucky enough to receive a lot of sunshine every year. While this can great if you want to hang out at the beach, it isn't so great if you need to drive. Driving in bright sunlight can be extremely hazardous, and sunglasses are a great solution. However, if you have issues with your vision, you may not be able to drive without wearing prescription lenses. Thankfully, the development of polarised and photochromic lenses means that you can enjoy the best of both worlds. Photochromic lenses will lighten and darken in response to the amount of UV light in the surrounding environment. A polarised lens will help to reduce the glare of the sun, which will help to reduce how tired your eyes feel.
