Fitting the replacement lenses

Gently pop the existing lens out of the frame by pushing with both thumbs, moving around the frame untill all the tabs have been released and the lens falls out.
Carefully align the replacement lense with the frame making sure the Rex Specs logo is visible from the outside. Shape the frame to fit the lense not the lense to fit the frame.
Check the frame has no gaps between the lens. 

FAQs

Do the clear lenses give the same UV protection as the tinted lenses ?
Yes they do. A way to describe our lenses is by their Visible Light Transmission (VLT). This is a measurement of how much light the lens allows to pass through to the eye. A low VLT allows very little light through, and a high VLT allows a lot of light to pass. This has been broken into 5 categories – they are listed below.

Category 0 - 80-100% VLT (lots of light passes through)
Category 1 - 46-79% VLT
Category 2 - 18-45% VLT
Category 3 - 8-17% VLT
Category 4 - 3-8% VLT (not much light passes through)

Clear lenses allow 92% of light through. Category 0

Yellow lenses allow 87% of light through. Category 0

Pink mirror lenses allow 37% of light through. Category 2

Purple mirror lenses allow 27% of light through. Category 2

Smoke lenses allow 24% of light through. Category 2

Red mirror lenses allow 23% of light through. Category 2

Green mirror lenses allow 16% of light through. Category 3

Blue mirror lenses allow 14% of light through. Category 3

Silver mirrorlenses allow 13% of light through - the most protection. Category 3 

How do I tell the difference between V1 and V2 frames and lenses?

Version 1 has the Rex Specs logo on the lens while V2 has the logo on the frame - just above the right eye.

I am going bush walking and will be out when it is quite dark. Which colour will be best ?

I would recommend the clear lenses for evenings and night time and any of the other colours for day time.
Why not take more than one lens so you can swap them around if needed.

Do dogs really need UV protection ?
Yes. There are a number of eye conditions caused or compounded by exposure to UV rays.
Ultra violet light is known to cause various types of damage to the eye such as chronic sunburn to the eyelid and surrounding area due to lack of pigment, Chronic Superficial Keratitis (pannus), Cataracts and sun spots.

I am taking my Husky to the snow this winter which colour lense will be best ?
Refering to our table above, if it is a bright sunny day with reflected light from the snow, the Blue or Silver Mirror is your best option. If it is an overcast day, all of the other colours would be an excellent choice.
The mirror coating does not provide an increased level of UV protection but they do increase how cool your dog looks while on the snow fields. Allow extra time as people will want to stop you and ask questions about your dog and their Rex Scpes. Sadly they aren't that interested in you.

Note: Mirror lenses are the same darkness to look through as the smoke lens but have a mirror coating applied. This coating does scratch. We've made them as durable as possible - but if your dog goes after a rabbit in the rocks or bushes with their mirrored lenses - the lenses will show signs of the hunt. The UV protection is not compromised by scratches -
