I had both my eyes lenses replaced approximately 12 years ago. Costing over £4000. I never got on with the replacements and kept going back for check ups as I kept seeing blurry vision and double vision, for the first 18 months I was told your brain needs to adapt to the new lenses. 12 years on now and I have kept going back to see optical express, I was told to take 3 eye tests and they would let me know where and when, I went all over the country to these appointments, I kept getting told I needed glasses, I refused as I was told before my operation that I would never have to wear glasses ever again. It turns out now that I have to wear glasses because optical express wanted another £4000 to do laser correction. Be very carefully using this company as I am nearly blind now, I cannot drive, I cannot see products in a supermarket. Strange they have a get out clause in the small print that anything that needs doing should be done in the first 12 months of surgery, funny I was told my brain needs adjusting for the first 18 months. Be carful make sure you read any small print before signing or paying any money, they are rip off merchants.
