UV light filtering with multifocals

[Mcav8r]

I have an M+ in one eye - its not working as well as it should.

My question relates to something rather trivial though - as UV lights are used in entertainment to emphasise teh bright colours etc - its known as black light. To me however I can now see it! I see the light reflecting of virtually everything - not just the brightcolours. Black light now creates an annoying purple glare. If I can see this end of the light spectrum - are the lenses not doing their job in terms of protecting the retina from other dangerous wavelengths?

Because any IOL transmits more light than the human lens, especially when its cataractous many people complain of light sensitivity after cataract surgery. In fact cataracts are like having a pair of sunglasses on INSIDE the eye. After years like that it often months and months to the light sensitivity to see normal.

Also many people, me included, that do not have cataracts have problems with sensitivity to light. These often have big pupils, blue/gray/green eyes and fair complexions.

My final comments would be that it usually gets better with time and find your self some cool hats to wear if you don't want to wear sunglasses, tinted prescription glasses or photochromic lens (photogray, transitions)

Thanks for your reply, the purpose of the implant was to get rid of glasses.
I do now use sunglasses, but that causes other problems in that the pupil dilates a bit more and I get blurring  and poor quality vision. I now see that Lentis have changed their lens design.

You would have to check with company website to determine what part of the spectrum is blocked by their lens.

Consider wearing custom made glasses with UV-A, UV-B blocking coating.
