It is important that your frame is a good fit for two reasons. Firstly it must be comfortable and not constantly slipping down or rubbing behind the ears. Secondly if the frame is not fitting correctly it could affect your vision and you won't be able to see as well as you should be able too.
As an online practitioner it is not possible for us to fit your spectacles to you directly but we will always ensure they are set up properly before they are sent out. As long as you have followed our choosing a frame guidelines you should be off to a good start. In many cases your spectacles will fit as they come and do not require any further adjustments.
If however they are too loose, too tight or don't sit straight then you have two options. You can either fit them yourself at home, it is quite a simple process, or you can ask your local Optician to fit them for you. They are normally happy to do this but may make a charge to do so.

Too Loose

If your spectacles are too loose then the usual solution is to shorten the sides slightly by reducing the distance between the front of the frame and the top of the bend in the side. Usually referred to as length to bend. In order to shorten the side bend the tips firmly but gently over your fingers as shown.


A plastic frame may need some gentle heat first. A hair dryer is ideal but please be careful it is easy to melt your frame and damage the coatings on your lenses if you get them too hot. A few seconds under the heat should be enough. The plastic should be warm to the touch but not hot. Be careful not to burn your fingers either.
Aim for a gentle curve with a similar radius to how they were supplied and not a ninety degree bend as this will never be comfortable. Take it slowly in small steps until they feel snug. In the vast majority of cases you will only need to move the bend a matter of millimetres. If you make them too tight then straighten the side out slightly and move the bend further away. Each side will not necessarily be the same length after you have finished and the frame may no longer sit straight on a table but this is perfectly normal. Not many people are perfectly symmetrical.


If the spectacles still feel loose even though the bend is now in the correct place then the next most common issue is that the sides are too wide. You can bring them in by gently bending them on a stable flat surface such as a table. The sides should normally be perpendicular to the front, ie go straight back and not splay out or in.


With a metal frame you can also adjust the nosepads in and out to get a better fit. Noses come in many sizes and shapes but they are all basically triangular and wider at the bottom than at the top. We can use this to raise or lower the frame should it be necessary. If you have bifocals or varifocals we recommend contacting us for advice before changing the pads as it affects the optical centres of the lens.


In order to move the nosepads take one at a time between finger and thumb and ease them in or out as appropriate, the movement required is very minimal. Take care not to break the pad arm off. The bridge on a metal frame should not rest on the top of your nose but sit slightly above it.

Frame sitting correctly

Correct Adjustment

Frame sitting too high

Too high

Frame sitting too low

Too Low

Too Tight

If the frame is too tight when you receive it then look in a mirror and see how it sits, a frame that is too tight will often not rest properly on your ears. If the bend on the side starts before it will sit over your ear then you can lengthen the side by straightening it out, a plastic frame may need some heat as above. You will then need to put the bend back in by bending it gently between finger and thumb as above.
You can also move the sides further out by bending them gently where the side meets the front between finger and thumb.


Side Adjust 1


Adjust side 2

We recommend extra care when adjusting the angle of the sides on a supra frame which has a frame at the top but not at the bottom as too much pressure can chip the lenses. We would not recommend trying to adjust the angle of sides at all on a rimless frame due to the likelihood of breaking the lens. In both cases you should be able to shorten or lengthen the sides without any issues.

Frame not Straight

If the frame doesn't sit straight don't worry most of us have one ear slightly higher than the other and it is a simple matter to work out how to straighten them. The most important thing to work out is which way do I need to move the side so that it will sit correctly? Look into a mirror is the frame down on the left or the right? Remember the image is reversed.
If the frame sits too low on the right side we can either gently bring the right side down by bending it from the joint where the side meets the front. Or we could bring the left side up, the effect will be the same. If the left side is too low we can bring the left side down or the right side up. Or we can do a combination of the two. Your frame will no longer sit straight on a flat surface but this is perfectly normal. Do not be tempted to adjust the frame by twisting the bridge, although this is an easy fix it will affect your vision. Also make sure that the nosepads sit nicely on your nose, they are easily moved as shown above.

If you are at all unsure about making the adjustments required then contact us in the first instance for guidance or ask your local Optician to fit them for you.

Under no circumstances will Faversham Optical Ltd be held liable for any damage or injury caused by attempting to adjust your spectacles. We can not be held liable for any charges your Optician may make for adjusting your frames.

Ongoing Maintenance

Every frame will benefit from an occasional bit of TLC. Check that all the screws are tight and if not use a small electrical screwdriver to tighten them.
Your cloth as supplied should be sufficient to keep your lenses clean if used daily. Occasional washing will keep your cloth working well. We sell a range of spray cleaners that will give a great finish but if your spectacles get really grubby run them under a warm tap and rinse. Dry with a cloth, tea towel, towel etc but don't regularly use tissues or washing up liquid as these can scratch the lenses. Please don't use a brillo pad or kitchen pan scourer to clean your lenses, they will scratch!
