Lens Treatments

As a general rule, if you are long sighted your lenses will be thickest in the middle, gradually getting thinner towards the edges. If you are short sighted, your lenses will be thickest at the edges and gradually get thinner towards the middle. This is the case for all prescriptions but is more noticeable on higher prescriptions where you will also notice increased distortions in the lenses. In these cases, thinner and lighter lens materials can make a pair of spectacles more comfortable to wear as well as more cosmetically appealing. Flatter lens technologies are also beneficial in cosmetic appearance and many feature a UV filter as standard, but they truly shine when minimising distortions.

At Brownbills we are able to use in-house technology and our own experience to guide you on lens choices, including the ability to estimate lens thicknesses and calculate the benefits of different options.

Self-Tinting or Photochromic lenses provide a simple and convenient sun protective tint, eliminating the need to switch between spectacles and sunglasses in everyday situations. These ingenious lenses have an adaptive tint that reacts automatically when exposed to ultraviolet light, darkening to block out harmful UV rays. When you return indoors, the lenses gradually clear again providing you with clear and sharp vision in all lighting conditions.

Recent developments in photochromic technologies also mean that versions of these lenses can now react whilst driving too.

When light is reflected from shiny or wet surfaces, such as low sunshine reflecting from a road surface or glistening across the waves of a swimming pool, it causes glare which can lead to uncomfortable vision. Polarised lenses filter this reflected light eliminating the glare and providing comfortable vision even in the most challenging conditions.

Polarised tints are available on all of our sun-tinted lenses.

At Brownbills, many of our lenses come as standard with high quality anti-reflective and scratch resistant coatings. These provide an anti-static, water and stain repellent, and easy to clean surface to the lens, whilst giving the benefits of improved visual performance, enhanced cosmetic appearance and anti-glare for night-time driving.

We’ve all sat in a car at night and been dazzled by the oncoming headlights. Particularly, with modern advances in Xenon and LED headlights comes an increased light density and luminance which to many can feel a lot brighter and more blinding.

As well as incorporating the same properties as our anti-reflective and scratch resistant coatings as standard, the road clear coating significantly reduces the irritating glare and reflections from oncoming traffic, wet surfaces and other sources, giving you a clear view of the road ahead and getting you to your destination as safely and relaxed as possible.

Electronic devices such as LCD screens, TV’s, mobile phones and tablets emit blue light that can often cause discomfort and glare for the wearer.

As well as incorporating the same properties as our anti-reflective and scratch resistant coatings as standard, blue coatings provide long-term comfort for wearers that are frequently exposed to electronic devices. It achieves this by filtering out the blue light emitted from the device, whilst still giving the benefits of improved visual performance, enhanced cosmetic appearance and anti-glare for night-time driving
