1. Thin and Light Lenses
The thickness of your lenses can vary depending on your prescription. As a general rule if you are longsighted than your lens is thicker in the centre and if you are shortsighted then your lens is thicker on the edges.
Thin and light lenses reduce the overall thickness of the lens making them lighter, cosmetically improving the appearance and making your glasses feel more comfortable. All our thin and light lenses come with an anti-reflective coating to give you clear vision.
2. Ant-Reflective Coating
Reflections on your lenses appear unattractive and can be distracting. At Johns Opticians we can offer you an anti-reflective coating for your lenses to minimise reflections and improve your vision. It will also improve the appearance of your lenses as others will see your eyes rather than the reflections on your lenses. All our anti-reflective coatings come standard with a hard coat
We can also offer you an upgrade on the coating giving your lenses these four distinct properties.
- Improved anti-reflection to enhances comfort and style
- Enhanced Anti-static to repel dust so lenses stay cleaner for longer
- Super-Hydrophobic to resist water and stains and repel grease and finger prints, making it easier to clean your lenses
- Durable to give your lenses a better protection from damage during day to day use with an extremely hard scratch-resistant coating.
Transition lenses (also known as photochromatic) react in the presence of ultra-violet light. The lenses darken when you are outdoors to reduce glare and improve your vision. They gradually return to a clear lens when you are indoors. At Johns Opticians we can offer you the latest Transition Signature VII Adaptive Lenses giving you maximum clarity indoors and outdoors.
4. Polarised Lenses
Sunglasses are designed to reduce brightness, however glare from bright sunlight can still cause squinting and eyestrain. To avoid this at Johns Opticians we recommend polarised lenses.
Glare is caused by horizontally reflected light from flat surfaces such as road or water. Polarised lenses block out these horizontally reflected light and only let through vertical light. Polarised lenses are useful for driving, fishing and skiing.
5. UV Coating
Light plays an important role in your children’s lives.
- For their vision – it helps them perceive and appreciate their surroundings.
- For their development – clear vision is essential to enhance their learning skills.
- For their well-being – it helps regulate their sleep cycles, mood, memory etc.
However they are more sensitive to harmful light exposure.
- UV Rays – which can accelerate opacification of the crystalline lens and can damage their retina.
- Blue Violet Light – Children learn to use modern devices earlier in life and on average spend about 3 hrs per day exposed to tablets and smartphones screen blue violet light.
Our latest UV coatings gives the highest protection for you and your child’s eyes.
- Best blue-violet light filtration on a clear lens.
- Best UV protection – children’s eyes are 25 times better protected against UV rays than without lenses.
- Excellent transmission of essential visible light
- Most resistant lens material – almost unbreakable (polycarbonate lenses)
- Easy cleaning (smudges, dust, water droplets), scratch resistance and anti-reflective efficiency for durable transparency.
