SPACE AGE LENS TECHNOLOGY IS NOW ON YOUR DOORSTEP

Spectacles are an integral component of daily life for many people. While contact lenses are an increasingly popular and user-friendly alternative, the simplicity and convenience of spectacles ensures they're still the default option for vision correction.

Lens technology has evolved greatly in recent years and it's now easy to buy spectacles that can block UV light, or prevent the build-up of grease and dirt with oil-resistant films. Much of this sophistication involves transparent chemical coatings applied to the lens and performing specialised duties such as preventing reflections. This concept was developed from the late 19th century onwards, with a major breakthrough occurring in the 1930s when scientists began combining thin layers of film that refract light at different angles, virtually eliminating reflectiveness.

The attendant benefits are particularly pertinent today with glare being alleviated from computer screens and mobile devices, while motorists benefit by avoiding dazzle from oncoming vehicles or street lights when travelling at night.

Nowadays, anti-reflective coatings are fairly standard on spectacles, and they are increasingly being augmented by scratch-resistant technology. It is worth noting that lens materials are far more robust nowadays, and the plastic commonly used in their manufacture has intrinsic scratch-resistant properties. Sporting or shatter-proof lenses typically utilise polycarbonate materials, whose softer composition relies on scratch-resistant coatings for durability.

As many spectacle wearers will testify, acute fogging can be caused by rapid changes in temperature or ambient conditions. Using technology pioneered by NASA and now available at Martin Reynolds Opticians, anti-fog systems prevent the build-up of condensation.
