It is generally desirable to maintain ocular side curves within which range?

Maintaining ocular side curves within the range of -4.00 to -7.00 is important for various reasons related to the fitting of contact lenses and the overall health of the eye. This range typically ensures that the lenses align well with the curvature of the cornea, facilitating both comfort and visual acuity. A proper fit helps to stabilize the lens on the eye, reducing movement and potential discomfort during blinking.

Furthermore, adhering to this range helps balance the relationship between the lens and the tear film, which is crucial for maintaining moisture and preventing dryness. Properly fitting lenses can also minimize the risk of corneal complications or irritation, making this range particularly favorable for practitioners aiming to provide optimal patient outcomes.

The chosen range indicates a standard that has been validated through clinical practice, helping to ensure that patients experience the best possible effectiveness and comfort from their lenses.
