Yes, but I don't think there's more UV during an eclipse (even in proportion to visible light). Overall, there should be less UV than there would be from viewing the full sun. The issue you mention does come up if you have a filter that blocks visible light but not UV. Non-UV-blocking sunglasses, for example, could increase the risk of cataracts compared to not wearing sunglasses at all (mainly because of pupil dilation).
