Here are a few tips when it comes to choosing prescription lenses and how to obtain your prescription.
Obtaining your prescription:
When you had a sight test your optician may or may not given you a written copy of your prescription. If you have a copy, and the test was within the last 24 months, you can fill in your prescription online and order your lenses.
If the optician did not give you your prescription you can ask for a copy. The optician is legally obliged to provide you with a copy of your prescription. Alternatively, we can contact your optician on your behalf and get your details.
Your prescription must be no older than two years. The recommended interval between eye tests varies depending on your age and health.
You have plenty of choices when it comes to choosing lens coatings, tints and material- 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 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.
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)
NOTE: High Prescriptions:
Lens prices quoted on our website are for stock range lenses. If your prescription is high (over +5.00/-6.00sph and/or over +/- 2.00 cyl) or your lenses require a special size/tint/coating then we can order custom made lenses for you. Will inform you should this incur extra charges.
Most of our vintage and reproduction frames can be fitted with these lenses. Please also check out our Black Eyewear Vintage inspired Eyewear Glasses & sunglasses, by Robert Roope, which all can also be glazed into prescription glasses.
