I feel that we need to see an uptick in automation/computer vision in the machines at the opticians before we're likely to see any sort of capability of the same at home. I would feel safer if the machines made diagnoses and there was an onsite optometrist/ophthalmologist for verification.

Also some conditions such as glaucoma can be difficult to test (http://www.glaucoma.org/glaucoma/diagnostic-tests.php). I remember one of the tests is to use a tonometer to check pressure by firing a puff of air at the eye, so for any of the tests today that give output values, these could feasibly be administered at home but wouldn't form a complete picture of our eye's health.

Interesting to think what an "opticians" could be in 20 years from now.

State of the art in eye imaging sensors is the equipment used in Lasik surgery. Already being used to supplement smaller opticians with remote optometrists, https://news.ycombinator.com/item?id=15374489
