ALTIUS AVIATOR SUNGLASSES FOR PILOTS

All Sports European-designed aviators combine strength, style, comfort and cutting edge lens technology to provide you with the ultimate sunglasses for pilots. Available with red or grey lenses - see below for more details. If required, you can also order a full prescription service for the grey pair (also see below).

Altius have a build quality and feature list that makes them outstanding value for money when compared to alternative high-end brands.

The Frame

Manufactured from a tough nickel silver, the top quality Altius frame is extremely robust, with solid sprung hinges that do not exhibit the slop associated with cheaper sunglasses. Adjustable nose pads and rubber side arm extensions enhance comfort levels. Finished in an attractive silver colour. The side arms are indented to ensure they fit comfortably beneath a headset.

The Lenses

Utilising Rapid Eyewear's Multi Layer technology, Altius lenses are packed with features. Made from impact resistant polycarbonate, the lenses are finished with a flash mirror coating that makes them look very attractive whilst reducing extreme light that can cause problems at altitude.

We are pleased to offer two versions of Altius. The Category 2 red lens set is ideal for fairly bright or changeable conditions; the grey category 3 lens is for bright sunshine.

Altius lenses have a hard coating to make them as scratch resistant as possible. They also benefit from hydrophobic and oleophobic coatings, which resist grease and water.

By filtering blue light from the spectrum, Altius lenses improve depth perception and contrast, making it easier to judge the terrain and sky ahead and below.

Prescription Options

We can add your prescription lenses to Altius if required - please note this service is only available for the grey category 3 pair. To select a prescription option, use the drop-down menu at the top of this page, then enter your details in the boxes that appear. We can only add prescription strengths up to plus or minus 4.5 SPH - this is a strict rule, so please do not order this product if your requirements exceed 4.5. You can choose from the following options (please note that a mirror finish is not added as standard):

• Single-vision without flash mirror coating
• Single-vision with flash mirror coating
• Bifocal without flash mirror coating
• Bifocal with flash mirror coating

The lenses we use are C39, a material renowned for its robustness, opacity and anti-scratch properties. An anti-reflective coating is added to the rear of the lenses - please note the prescription lenses do not have oleophobic and hydrophobic coatings.

From the date of order it will take around 1-2 weeks to complete and ship the sunglasses to you. Orders with the flash mirror coating will take a little longer than the standard options.

Pupillary Distance (PD)

This is the distance, in millimetres, between the pupils of your eyes, when measured across the front of your glasses. PD's typically fall in the range of 55 up to 70mm. If you choose to have us make up your prescription sunglasses, we will need to know your PD. Opticians measure PD during an eye test, but they often do not put the result on a prescription card provided to the patient. If you do not know your PD, please ask your optician what it is. Unfortunately, some opticians will not release the measurement and in the USA, they are not obliged to do so.

You can measure your own PD easily. With your regular glasses on, ask someone to hold a ruler up against your glasses and measure off, in millimetres, the distance between the centres of your pupils.
