This 3-second test separates a basic eye exam from a precise one.
It’s called the Jackson Cross Cylinder (JCC).
It fine-tunes the axis and power of astigmatism to microscopic accuracy.
Because your eyes deserve more than approximation.
At Ultra Eye Clinic, clarity is engineered — not assumed.
Save this so you understand what’s happening at your next eye test. 👌🏾✨
