Designer Sunglasses - Designer Eyeglasses
The combination of these points of adjustment can make the glasses feel
comfortable and relaxed on your face, but it requires all points to be
worked together and in a choreographed sequence in order for the
operation not to become “Rubik Cube” like.
The first thing to do is to ensure that all points of contact are tight and firmly connected
– so check each screw to make certain that it is tight. This will
ensure that any further adjustments not only work correctly, but also
stay in place for a reasonable amount of time. The usual symptom of
“having a screw loose” is that the sides of the frame become loose and
floppy on your face – so that is always a good place to start.
If the
glasses are slipping down
on your face, it is likely that the sides of the frame are not
symmetrical and one or both need some adjustment. Place the glasses face
down on a white towel or sheet and looking straight down at the lens
along the side frames, see if they are directly perpendicular and
orthogonal to the front frame. If one or both are not then prepare to
adjust.
All frames have some metal running down the centre of
them, and it is this that needs to be bent back into shape – that’s one
of its purposes ! The difficulty is that the metal is often coated or
surrounded n plastic or acetate that is prone to cracking or breaking
when bent.
The best way to approach this dilemma is to heat the sides of the frames with a warm air source
– a domestic hairdryer works very well – and then adjust each side
alternatively in small increments until they have achieved the
regularity of the frame.
In the case of metal frames, the glasses
can be made to sit higher or lower on the face by adjusting the
nosepads inwards or outwards. Again, take care and do each one
alternatively and incrementally so that you can measure the result from
each tweak and adjust accordingly. Plastic frames generally do not have
nosepads.
Each of these needs a different approach, and each
has many pricey products that you can go out and buy in your local
chemists or pharmacy which work well –
but here are some simple and everyday solutions :For
the lens : The most important thing is to be gentle with any
chemicals/detergents or rubbing agents. If the glass is just dirty, and
not covered in grease from when you adjusted your glasses with the hand
that just managed the ingestion of your cheeseburger – then the classic
slow but steady breath onto the lens followed swiftly by a gentle
massage with a good quality linen or cotton cloth still works well. When
you have transferred remnants of your lunch to the lens however, some
chemical introduction coupled with temperature takes it to the next
level.
For normal glass or plastic lenses, a
quick dunk in a pool of warm water with a couple of drops of washing
detergent will usually do the trick to break through the grease. Of
course if warm water isn’t available, a quick spray with a
commercial/domestic window cleaner also does well. Be Careful however if
you have an anti-reflection coating on your lenses – which is common on
glasses that have been prescribed for night driving – as the surface of
these lenses have been treated and washing up liquid or detergents will
often smudge the lens even more and just make the situation worse. For
this situation, you are better off with an optical spray and a nice
clean cloth. The tip here is that it doesn’t have to be a glasses spray
from the opticians – any optical spray (for cameras for example) will
work just fine.
For the nosepads :
The surface of the nosepads are generally quite resistant to dirt and
natural oils. They are usually made form a type of plastic or acetate
–and so are not prone to reactions with the skin. Dirt can easily get
lodged however between the nosepads and their mounts or the frame itself
– so a warm soak for a couple of hours overnight will soften the
residue – which can then be gently brushed away with an old soft bristle
brush or toothbrush.
