When Erasing EPROMS, is erasing the EPROM bad when you use the UV light longer than 30mins?

What do you use to cover up the EPROM so light doesn't get into it? so it doesn't erase it or mess it up?

I have been programming EPROMS chips and between a week or a month the EPROM chips will creates distorted waveforms or digital waveshapes signals or errors , what is the cause of this?

Is it because my UV Erasing Time is set to long?

The datasheets says between 10 to 15 mins when erasing using a 15000 UV lamp light but the UV lamp light I'm using is only 8000 UV lamp to do the erasing

Setting the Erase time to 55 mins will destroy the cells or something in the EPROM chip?
