That was the fee at the Costco optometrist here around fifteen years ago. I went once and he didn't charge me extra for the retinal examination.
Now a refraction plus dilation and several optical tests brings about $350 at a full-service optometrist.
I get my refraction from my Optometrist, I go to Walmart and buy a pair of frames at a fraction of the cost the Optometrist charges. Have to sign a waiver, but it is worth it. $20 pair of nice frames vs $500. Lens are $350 with no coatings as I wear no line bifocals. but all else from the Ophthalmologist and it is expensive, because I’ve had cataract and Lasix, I tend to develop dry spots on the Cornea. The first Cataract removal was a disaster, he left the cornea like a football and put in the wrong lens. 2nd one different surgeon and it went well. But the differences in the 2 eyes created a misconnect in the brain and I saw print as TINY. So ended up with Lasix to fix that.And no Tricare doesn’t cover that, just the Cataract removal.
