The Lomo LC-A camera page is here. The biggest accessory is perhaps the Instant back. It has a page here. On this page you will find some accessories I found for cheap.
Lens Attachments
Two lens attachments in their boxes and a camera.
As the Lomo LC-A lens is built into the body, only lens attachments
are possible. But there is no filter thread, so it's a bit more
complicated. The attachments are held by strong magnets. Lomo provides
self-adhesive metal rings to glue around le opening in the housing.
It's easier on the LC-A + model, which has an accessory groove to slide
a holder onto the housing.
Tunnelvision Attachment and Close-Up Lens
This is a double use attachment. The Tunnelvision Lens provides
provides a special distorsion with a sharp center and soft areas. There
is vignetting at the corners. The front part of the attachment can be
unscrewed. The remaining lens part is a close-up lens down to 2.5 cm.
What's in the box: lens attachment, 2 caps, pouch, self-adhesive metal rings an instructions.

Filter Holder
This is a bit of DIY stuff based on the Splitzer For the LC-A +. The
splitzer is gone, there is a skylight filter in the openening, wich can
accept further filters via its thread. The holder is made for the
accessory groove in the + model, the ordinary LC-A has to be modified.
Either you dremel the groove into plastic of your camera or you swap
the front part against a spare from the + models. This is easy, it's
only 4 screws to unscrew, swap and rescrew. The + models are prone to
electronic failures, so you may find a broken one for cheap.
The holder and some filters.
One filter in place.
If you use filters, think of the filter factor. As the sensor of the
camera is not covered by the filter, it cannot take it into account.
You can adjust film ISO setting instead. But please don't forget to set
it back when there is no filter again.
20mm Wide Lens
This is an accessory for the + model as well. As for the filter holder, the
ordinary LC-A has to be modified. Either you dremel the groove into
plastic of your camera or you swap the front part against a spare from
the + models. This is easy, it's only 4 screws to unscrew, swap and
rescrew. The + models are prone to electronic failures, so you may find
a broken one for cheap.

There is a new distance scale, you can focus much closer.

Camera with lens attached. It's now 20mm ultra wide, near to the very
expensive LC-Wide with its 17mm lens. However it's less compact and
it's quite heavy. The lens shade ring only moves forward a little bit
but might be helpful in case of. The cap has a hand strap, so you won't
forget it on the scene.
