How to measure a PD (pupilar distance)

PD is the distance between the centre of one pupil to the centre of the other pupil. Prescription glasses are made so that the distance between the optical centres of the glasses' lenses, is the same as your PD. PD varies from person to person but once you are an adult, your PD does not change. Therefore, as an adult, if you have had it measured, then it will still be the same, even if your spectacle prescription has changed. Once you know your PD, you do not need to measure it every time you buy prescription glasses.

PD is measured either during the eye test or when prescription glasses are ordered. Obviously we cannot measure your PD over the internet, so it is best to make sure your PD is included in your glasses prescription.

The Diagram below represents a PD of 62mm.

If your prescription does not contain your PD:

• Ask to have it measured at an optical shop – some may charge a fee.
• Contact an optical shop where you have previously purchased prescription glasses. Your PD has been measured if you have ever had prescription glasses made up.
• Your previous optometrist may have a record of your PD.
• Alternatively, try measuring your own Pupillary Distance as explained below. (Note: Measuring your own PD may not be as accurate as having a trained person do it. If your head or the ruler moves during the measurement then the reading will be inaccurate)

The higher the lens power in the glasses prescription, the more important it is to use an accurate PD. These procedures may not work for everyone. We recommend that you obtain a professional measurement of PD whenever possible.

Measuring your own PD (Pupillary Distance):

TIP: This should be done with glasses off, if the numbers on a ruler are difficult to see, then a magnifying mirror may help.

1. Whilst looking into a mirror hold a ruler against the bridge of the nose with one hand.

2. Close your left eye, and line the '0' up with the centre of the pupil of your right eye as shown in the diagram.

3. Without moving your head or the ruler open the left eye and close the right eye. Read the number that lines up with the centre of the pupil of the left eye. This number represents your Distance PD in millimetres. You have just used this technique to measure your distance PD.

4. Repeat this whole process at least 3 times to try and get a consistent measurement in millimetres. Make sure your head and the ruler do not move after lining up the zero on the ruler until you take the reading. This procedure may be difficult if one eye has very poor vision compared to the other eye.

When you enter your Pupillary Distance (PD) details on the Stingy Specs glasses prescription form, enter the number you have just measured – this is your ‘distance PD.’ You then need to enter your ‘near PD’ which is calculated as 3mm less than the distance PD.

e.g. Distance PD = 60
Near PD= 60 – 3 = 57

Sometimes the centre of the pupil is difficult to see. Instead of lining up the ruler with the centre of the pupil, it is more precise to use the edge of the pupil as shown at the bottom of the page; (be careful to use the inside edge of one pupil and the outside edge of the other pupil.)

Getting a Friend to Measure Your PD:

This technique uses a second person to measure your Pupillary Distance (PD).

1. Both of you should be sitting down approximately 45cm apart. The person having their PD measured keeps both eyes open. When your friend is taking the measurement, they must keep one eye closed.

2. The ruler is held against the forehead as shown above. The person having the PD measured looks into the open eye of the person taking the measurement.

The “0” is lined up with the centre of one pupil. Record the number lining up with the centre of the other pupil in millimetres. This is the measurement for the “near PD”. Neither person should move their head during this procedure. This procedure will not work if the person having their PD measured has a turned eye. You have just used this technique to measure your near PD.

When you enter your PD details on the Stingy Specs glasses prescription form, enter the number you have just measured into the “near PD” field. Enter your “distance PD” which is calculated by adding 3mm to the “near PD.” (This rule is accurate for most people).

Eg Near PD= 57
Distance PD= 57 + 3= 60

Instead of using the centre of the pupils, you can use the edge of the pupils as shown below. (be careful to use inside edge of one pupil and outside edge of the other pupil.)

Please note that when you measure your own PD by using these techniques you may not get the same result as an experienced professional. We recommend that you use the measurements taken by an optometrist or an optical dispenser whenever possible. This page is provided for information purposes only.

What is UV Protection?

The sun supports all life on our planet, but its life-giving rays also pose dangers.

The sun’s primary danger is in the form of Ultraviolet (UV) radiation. UV radiation is a component of solar radiation, but it can also be given off by artificial sources like welding machines, tanning beds and lasers.

Most are aware of the harm UV radiation can do to the skin, but many may not realize that exposure to UV radiation can harm the eyes or that other components of solar radiation can also affect vision.

There are three types of UV radiation: UV-C is absorbed by the ozone layer and does not present any threat; UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.

If your eyes are exposed to excessive amounts of UV radiation over a short period of time, you are likely to experience an effect called photokeratitis.

serious. Scientific studies and research have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of developing a cataract and may cause damage to the retina, a nerve-rich lining of the eye that is used for seeing. Additionally, chronic exposure to shorter wavelength visible light (i.e. blue and violet light) may also be harmful to the retina.

The longer the eyes are exposed to solar radiation, the greater the risk of developing later in life such conditions as cataracts or macular degeneration. Since it is not clear how much exposure to solar radiation will cause damage, the AOA recommends wearing quality sunglasses that offer UV protection and wearing a hat or cap with a wide brim whenever you spend time outdoors.

To provide adequate protection for your eyes, sunglasses should:

• block out 99 to 100 percent of both UV-A and UV-B radiation;
• screen out 75 to 90 percent of visible light;
• be perfectly matched in color and free of distortion and imperfection; and
• have lenses that are gray for proper color recognition.

The lenses in sunglasses should be made from polycarbonate or Trivex® material if you participate in potentially eye-hazardous work or sports. These lenses provide the most impact resistance.

If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation.

Be sure to see your doctor of optometry at least every two years recommended schedule of examinations for a comprehensive eye examination. It is a good way to monitor your eye health, maintain good vision and keep track of your solar radiation protection needs as well as new advances in eye protection.

What are the advantages of wearing sunglasses

Contrary to popular belief, sunglasses aren’t only intended for fashion and comfort. They block UV radiation, protect eyes from sunburn, and help prevent cataracts. There are several other medical benefits to wearing sunglasses depending on the medical condition, here is a list of some medical benefits to wearing certain types of sunglasses.

UV Protection

First and foremost, many sunglasses today come with UV protection to shield the wearer’s eyes from harmful UV rays of the sun. UV rays can provoke cataracts, cornea damage, and many other harmful effects to the eye. Today the science of UV protective sunglasses is near perfect, with many brands offering 100% protection from UVA and UVB rays.

Reduce Headaches and Eyestrain

Intense sunlight can cause migraine, tension, and other types of headaches. This can be caused by bright sunlight evoking eyestrain, UV rays from the sun damaging the cornea, and other headache-inducing effects of sunlight. By wearing sunglasses under bright conditions, headaches can be reduced and in some cases even prevented.

Keep Your Eyes Wet

By blocking the sun’s light and heat, sunglasses can help keep the eyes moist by lessening the evaporation of tears. The eyes need moisture to focus and perform correctly, so proper sunglasses can actually improve vision under intensive sunlight.

Medication-Induced Photosensitivity

Medication-induced photosensitivity is an abnormal sensitiveness to natural or unnatural light as a result of a side effect from a prescribed medication. Antibiotics and anti-inflammatory drugs have been known to cause photosensitivity. When this happens, normal light conditions become overbearing and irritable, and can induce headaches, pain, and other symptoms. Wearing sunglasses can reduce the side effects of medication-induced photosensitivity by subduing the light that enters the eye.

Reduce Effect of Jet Lag

Jet lag is the disruption of one’s biological rhythms due to plane travel through different time zones. This effect is related to human biology, not psychology like many may assume. Sunglasses are effective in preventing jet lag by tricking the human body in believing that it has not passed through a different time zone. This works by reducing the sunlight that enters the eye and blurring the body’s awareness of time change.

Eases Photophobia

Like photosensitivity, photophobia is an acute sensitivity to normal light conditions, only photophobia is not induced by medications. It is usually a symptom of another disease or infection. Patients that have photophobia typically experience moderate discomfort to severe pain in average light situations. Sunglasses ease the pain and discomfort caused by photophobia by lessening the amount of sunlight that reaches the eyes.

Medical and Industrial Trade Sunglasses

Since many industrial and medical trades utilize tools that emit strong UVA and UVB rays, it’s necessary for most workers in these environments to wear sunglasses for safety purposes. Welding torches emit UV rays, as do laser surgery tools used in hospitals. Surgeons and dentists will commonly use laser safety glasses for themselves and their patients during laser surgery. These glasses and goggles are individually tailored to block certain types of rays that are specific to the trade. Types of tinted lenses for these trades include, welding glasses, arc wielding goggles, blowtorch goggles, and laser safety glasses.
