Q. How do I know what size to buy?

You can then use the following chart as a guide only:

 Suggested Frame Size: Face Size (temple to temple)
47mm 115mm or 4.50"
52mm 127mm or 5.00"
55mm 135mm or 5.25"
57mm 140mm or 5.50"
58mm 146mm or 5.75"
61mm 152mm or 6.00"


Q. I have a broken lens in my Randolph sunglasses. Can they be replaced, and if so, how much will they cost?

 A. Scratched or broken lenses are not covered under warranty; however, you can purchase new ones right here on our website: Replacement Lenses

Q. How long will my order take to ship?

A. Typically your order will ship within 2 days unless there is a problem with inventory.

Q. How do I care for my sunglasses?

A. For everyday cleaning, simply wipe both the frame and lenses with a lens cleaning and polishing cloth. For a more thorough cleaning, wash the frame and lenses with a mild soap or detergent and warm water, rinse and shake dry, then wipe off excess moisture with the lens cleaning and polishing cloth.

If the temples become too loose over time, simply tighten the temple screws using a small screwdriver.

Q. What Is The Difference Between Bayonet, Cable And Skull Temples?

A. The temples are those arms which go from the front of the sunglasses frames back along the side of your head to your ears.

Bayonet temples go straight back and do not curve downward over the ear. These are an excellent choice for anyone who wears any kind of head gear like helmets, headsets or hats.

Cable temples go straight back and curve down the back of your ear and under the ear providing the most secure type of temples to prevent your sunglasses from falling off of your head.

Skull temples go straight back and curve down the back of your ear but not under the ear. These are often referred to as "hockey stick" temples, and are the most common form of temples found on eyewear. The choice of temples should be made on the basis of the conditions you intend to use your sunglasses in with an eye towards maximum comfort.



Q. What Is The Difference Between Crown Mineral Glass Lenses And Glass Lenses?

A. Crown mineral glass sunglasses lenses are used in high quality sunglasses because of their low refractive index and low dispersion factors. Visual acuity is an indication of the clarity or clearness of one's vision. It is a measurement of how well a person sees. Crown mineral glass lenses also are more resistant to scratches, and will keep your eyes cooler even after long hours of exposure to harsh, hot sunlight.

Q. What Is The Difference Between Steel Alloy And Nickel Silver Alloy?

A. Most sunglasses manufacturers use monel or steel alloy for the eyeglass frames. As you know steel will - over time - oxidize and begin to rust. If you use steel in the eyeglass frames it will - in time - begin to corrode and the finish will pit and then wear off. Nickel Silver alloy will not rust over time, and it also accepts the finish coating much better than steel alloy. Each frame is placed into a tumbler with round, smooth rocks to knock off any imperfections or small metal spikes before the finish is applied. Randolph Engineering uses 18% nickel silver alloy metal for all of its sunglasses frames, providing excellent solder joint integrity and frame durability. This is why after over 30 plus years the frames are still in excellent condition and we get requests for lenses to replace!

Q. What are polarized lenses?

A. Polarized lenses reduce glare from reflective surfaces such as water, snow, or the hood of a car. This is done through a process called polarization, which works much like Venetian blinds reduce sunlight through a window.

Basically, sunlight is either absorbed or reflected horizontally, diagonally or vertically through polarized light-waves. Horizontal polarized light-waves cause the most problems for the human eye. When light reflects off of a horizontal surface, it hits your eye at the same angle. As a result, the glare you see is even stronger than the ambient sunlight around you. Polarized lenses have a filter containing tiny horizontal blinds that allow only vertically polarized light to enter your eyes. Glare is eliminated because the horizontally-polarized light can’t get past the horizontal blinds.

Since glare (or horizontally-polarized light) is 7-10 times stronger than ambient light, it’s extremely harsh on your eyes, resulting in fatigue or headaches. Our Polarized Gray lenses filter glare at above industry standards for further protection and visual clarity.
