Compatible with Ray-Ban Meta Wayfarer Eyeglass Nose Pad, 8 Pairs Soft Silicone Nose Pads, Anti Slip Replacement Nose Pads

I purchased these nose pads for my new Meta Ray-Ban Wayfarer sunglasses. The glasses would slip a bit on my nose without nose pads. The nose pads I purchased were advertised to be compatible with the Ray-Ban sunglasses.When the nose pads arrived, my wife opened the package and 2 of the nose pads fell out. Not a good start. We swabbed the sunglasses with alcohol. The nose pads went on as advertised, although the bottoms of the purchased pads did not attached to the glasses. This did not seem to make a difference, since the majority of the purchased pads attached themselves to the glasses.My first impression was that they pushed on a very small part of my upper nose. I thought this was odd, but did not think it would be a problem.After wearing the sunglasses with the purchased pads attached for a few hours, I noticed that the sunglasses did stay in place and did not slip. This was very good.The problem began as I wore the glasses throughout the day. The purchased pads were pressing into my upper nose area and causing me to have a headache. Not sure why, but it was becoming unbearable.The purchased pads are oval or rounded in shape. This puts all the pressure of the glasses on two small points in my upper nose, resulting in a painful headache. I tried the sunglasses the next day with the idea that I would become accustomed to the new pads. After wearing the sunglasses for an hour this morning, the pain had returned. I pulled the pads off and have been wearing the sunglasses for the past 2 hours with no pain or problem.I returned the purchased pads and have ordered another brand with the hope they would work and not cause me any pain.
