Tint Density

The tinted lens actually absorbs the tint color into the lens material. Tint density is defined as a percentage, where 0% is completely clear, and 100% permits no light to pass through (solid). A 15% to 25% tint is used for a fashion tint, and a 50% to 85% tint is used for outdoor protection from the sun.

For driving, yellow lens help you distinguish contrasts, which can aid in driving. They can also be effective for foggy or hazy daylight conditions.

For sun protection, you would use a 50% tint for all around use, both during midday and during morning and evening hours when there is less available light. A 50% tint is a better all-around lens.

For bright light situations, like midday sun on the water, an 85% tint provides maximum protection from the bright sun.

Pupillary Distance (PD)

The Pupillary Distance (PD) is the distance between the centers(pupils) of your eyes, measured in millimeters.

An accurate PD is a required measurement to make your prescription glasses. Your optometrist can provide this to you with your eye test.

A PD measurement is also something you can measure yourself with the help of a friend.

SPH Sphere

The Sphere Power(SPH) is the amount of long or short sightedness and will always have a plus (+) or minus (-) sign in front, or above, of the number.

The positive and negative values are not the same.

Please be extra careful with this when entering your prescription. If your prescription only has one number for each eye, then this is your Sphere Power.

CYL Cylinder

The Cylinder (CYL) is the measurement of your astigmatism and also has a plus(+) or minus(-) sign present.

The positive and negative values are not the same.

Please be careful with this when entering your prescription.

Axis

If you have a value for Cylinder, you will also have an Axis value.

If you have no Cylinder value in one or both eyes, your Optometrist may just write the Sphere Power alone or PS in the Cylinder section.

ADD

The Additional ADD value is for those requiring reading glasses or bifocals.

It indicates the power added to your Sphere value for reading or close up work.

If you have a prescription for reading glasses or bifocals, and you only see one ADD power, it is understood that you have the same ADD for both eyes. If you do not see an ADD power, leave it blank.

Left(OS)

Left eye. The second line of your prescription is for the left eye, sometimes referred to as OS.

Right(OD)

Right eye. The first line of your prescription is always for the right eye, sometimes referred to as OD.
