Choosing prescription glasses

When it comes to selecting the right pair of prescription glasses there’s plenty of choice regarding lens coatings, tints and materials- so we thought we’d explain a little more about the differences….




  • Anti reflection Coating: This coating is a multi-layered coating which reduces the reflection & glare on the surface of the lens. This helps when driving at night and working at the computer screen. Adding the coating also has a cosmetic effect, making your eyes more visible behind the lens. Every Antireflection coated lens is also hard-coated.
  • Hard Coating: This coating hardens the surface of the lenses in your prescription glasses, making them more resilient against scratches.
  • UV400: This coating filters out 100% of all UVA & UVB radiation. This is a clear coating and not to be confused with a dark sunglass tint, which filters out the sunlight.




  • Sunglass: The sunglass tints we have on our website are solid, even tints which absorb around 75-85% of sunlight.
  • Graduated: Graduated tints vary in colour intensity, usually dark at the top and gradually fading to clear at the bottom.
  • Transitions: These lenses, also known as Photo chromatic lenses,  will change colour when exposed to outdoor sunlight. They will turn back to clear when inside a room.
  • Polarizing: These lenses have a solid dark tint and polarizing filter. This filter will only allow light of a certain angle though the lenses, reducing reflection seen on water or glass surfaces.


Lens thickness:


If you have a strong prescription you may be familiar with the choice of lenses materials. If not here is some info on when it is recommended to choose thinner lenses. As a rule of thumb: the higher a prescription the thicker the lenses will be. To reduce this thickness you can choose thinner lenses. These lenses are thinner because they are made from a higher “index” plastic material

  • Standard lenses: These plastic lenses have an index of 1.5 and are commonly used for prescriptions up to +/- 2.50 dpt.
  • Thin lenses: On our website thin lenses are a 1.60 index and are recommended for prescriptions between 2.50 – 4.00 dpt.
  • Thinnest lenses: The thinnest lenses we offer on our website are a 1.67 material and recommended for prescriptions over 4.00 dpt. (Please note: for very high prescriptions we can also supply the highest index material of 1.74, please contact us with your prescriptions for a quote)
