How to choose a frame to suit your face shape
Whilst there are no hard and fast rules we have
compiled a simple guide that will help you choose
the right style for your face:
People generally fall into the following categories:
 |
Square
Face:
Your face is as long as it is wide with a deep forehead and
a square jaw line.
Celebrities with this type of face include:
Elton John, Demi Moore and Sandra Bullock
Choose frame styles that are more rounded
or oval and avoid slim square or angular shaped
frames. |
| |
|
 |
Oval Face:
Your face length is roughly equal to one and a half times
the width. Your face is well balanced with
high cheekbones and a gently curving jaw.
Your forehead is slightly wider than your
jaw.
Celebrities with this type of face include:
Julia Roberts
You're in luck, most frame shapes suit your
face shape. Just make sure the size is in
proportion to your face. |
| |
|
 |
Round Face:
Your face is as wide as it is long and is fairly short in
height with a wide forehead. You have full
cheeks and a rounded jaw line.
Celebrities with this type of face include:
Cameron Diaz,
Choose frames with lenses that are wider
than they are deep and squarer in shape. Frames
that have decoration where the arm meets the
frame and with arms that meet the frame at
the top would suit. Avoid big round frames
that make your face look rounder. |
| |
|
 |
Heart-Shaped Face:
Your face is narrow at the jaw line with a small neat chin
and mouth and wide at the cheek bones and
forehead.
Celebrities with this type of face include:
Jennifer Aniston
Choose a frame style that is slender, rounded
or square but avoid a style that has a greater
width at the top. This will tend to reflect
the shape of your face rather than enhance
your look. |
| |
|
 |
Long Oblong Face:
Your face is longer than it is wide with high cheek bones
and a deep forehead.
Celebrities with this type of face include:
Choose wider frames and styles with a heavier
top. Strong looking large square frames can
often balance a narrow looking face. Avoid
small subtle shapes. |
If you are already wearing
glasses and are happy with your style then simply choose a similar
frame.

Understanding your prescription.
Making sense of your prescription is easier
than you would think if you understand the jargon!
Here are some terms used on your prescription:
SPH (sphere).
This is your correction for long
or short sight. It can be a ‘-‘ value
or a ‘+’ value and goes up in 0.25
steps. 0.25, 0.50, 0.75, 1.00 etc.
CYL (cylinder).
The correction for any Astigmatism
if you have one. It can be a ‘-‘ value
or a ‘+’ value and goes up in 0.25 steps.
0.25, 0.50, 0.75, 1.00 etc.
AXIS.
The axis for which the correction for the
Astigmatism needs to be set at. It will only be
present if you have a value in CYL. And can be
a value from 0 - 180
ADD (addition)
Only required if you need to use
glasses for reading and is always a ‘+’
value.
NEAR Means the same as ‘ADD’ above.
‘-‘ or ‘+’ This is VERY
important as it indicates short or long sightedness.
The ‘-‘ value is sometimes written above
the value.
PLANO
These all mean the same thing! No correction
required/nothing/0
0 }
0.00 }
INFINITY }
DS(dioptre sphere). Usually appears under the
CYL box and would indicate no CYL value.
OD When user refers to the right eye
OS When used refers to the left eye
If you require reading glasses please include the
NEAR or ADD. If you require Distance /Driving glasses
then you may omit this
You may also have an Intermediate value. This is
for computer use. Please call us if you need glasses
for VDU work and have this value on your prescription.

PD (Pupillary Distance)
This is the distance between the center of
one pupil to the center of the other pupil measured
in millimeters. Usually written as one value (60mm)
but sometimes written as 34/33 if one eye is slightly
further away from the center of the nose than the
other. Unfortunately, many prescriptions do
not include a PD measurement or Pupillary distance
measurement. Your Optician does not yet HAVE to
give you this as part of your eye test and so often
chooses not to so as to encourage you to pay over
the odds for your glasses rather than using our
fantastic service at glasses2you. So therefore we
encourage you to ask your Optician to supply you
with this measurement. However, don't panic if you
haven't got this or don't want to ask your optician.
We can still make your glasses up using an average
pupillary distance measurement based on your gender,
the size of the frames you have ordered and the
experience of our dispensing optician. In the majority
of cases this method works extremely well but there
will be certain customers who through having very
strong prescriptions or who significantly differ
from the average may encounter some problems. In
these cases the specs won't damage your eyes but
may well cause some discomfort. If you know that
you have a particularly strong prescription or you
suspect that you may not fall close enough to what
is seen as average sizes we would recommend that
you try one of the following methods of obtaining
your PD measurement.
Obtaining your own Pupillary Distance
Method 1: Ask your partner or friend to help you.
Make sure your friend is sat at roughly the same
height as you are and ask them to place a ruler
across the bridge of your nose upside down so
that the millimeter measurements are on the edge
of the ruler closest to your eyes. The measurer
holds the ruler in their left hand across the
bridge of your nose and closes their LEFT eye
to avoid any parallax error. With their RIGHT
eye open, they then first line up the ruler with
the center of your left pupil. Then without moving
the ruler they close their RIGHT eye and with
their LEFT eye open, read off the measurement
to the center of the RIGHT pupil. (See diagram
below). Best results are achieved if you fix your
gaze on the bridge of the nose of the person taking
the measurement. This point should ideally be
around 16 inches or 40 cm's away.
Method 2: Taking a measurement yourself
This is easily measured looking in a mirror and using a ruler!
Please follow these steps
- Stand in front of a mirror at a distance of
about 20cm (8 inches)
- Close your right eye
- Place your ruler flat against the mirror and
align it horizontally with the millimeter scale
pointing upwards
- Looking over the top of the ruler with your
left eye, align the zero mark of the ruler in
the center of your left pupil
- Now open your right eye and close your left
but keep your head still and the ruler in the
same position
- Read the millimeter measurement corresponding
to the center of your right pupil
- To be sure, you can repeat this process a few
times for consistency
Method 3: (With a helper)
Please follow these steps:
- Put your glasses on
- Ask your helper to stand in front of you and
mark a dot on your glasses directly above your
pupils left and right (Please
be sure to use a NON PERMANENT MARKER PEN)
- With a ruler, measure the distance between the
2 dots
