In recent years there has been major developments in spectacle lens technology, all designed to improve your vision and to make your spectacles look more attractive and be more comfortable to wear. We are happy to discuss which of these are appropriate for you and any budget that you may have.
Varifocal Lenses (the modern alternative to bifocal lenses)
These are normally advised for people over the age of 40 to avoid the need to put glasses on and off when reading. Unlike bifocals, there's no line on the lens; instead there's a gradual change in power as you look down giving you clear vision at all distances.
Alvaston Opticians offer a 1 month guarantee with all our varifocal lenses, meaning if you can’t adapt to them we’ll change them for you so you’ll never have to worry about purchasing glasses that you can’t wear.
Bifocal lenses are more convenient than separate pairs (for distance and near) and can be dispensed with the most appropriate width of reading area for your needs.
High Index Lenses
Some patients who have a more complex prescription have had to put up with thicker and heavier lenses in their spectacles. Today’s advances means super thin and lightweight high index lenses now make them look great and feel more comfortable too. Modern technology also means there is less edge distortion on the lenses offering a wider field of vision.
(lenses that change colour under different light levels)
Outdoors they develop a darker tint similar to sunglasses and indoors they go back to being clear lenses. They are available in grey or brown tints and offer 100% protection against damaging UV light. They help to keep your eyes comfortable and allow them to adjust to frequent changes in light conditions without the need to constantly put sunglasses on and off. They also offer 100% UV protection and have become faster acting in recent years. Now there's even a version now that can go darker behind a cars windscreen.
These are designed to reduce reflections from artificial lighting, computer screens, I Pads and car headlamps. They improve the appearance of your glasses by allowing people to see your eyes through your glasses more clearly without so much light bouncing back off the surface. Most importantly they give a better clarity of vision.
The best of these have the added benefit of them being scratch resistant, dust and water repellent and they help prevent grease debris on the lens surface. The newest one has a one wipe system making them even easier to keep clean.
All of our coatings come with a 12 month manufacturing faults warranty.
