Optical device with desensitized rotational angular alignment for astigmatism correction

An ophthalmic lens comprising:

• a main body having a toric surface and a spherical surface opposite the toric surface,
• wherein the spherical surface is configured to exhibit a lens spherical power,
• wherein the toric surface is configured to exhibit a lens cylindrical power based on at least a direction of astigmatism of an eye of a wearer and a target cylindrical power that would result in substantially full cylindrical correction,
• wherein the lens cylindrical power is less than the target cylindrical power, and
• wherein the lens spherical power is configured such that the minimum circle of the ophthalmic lens is on or adjacent the retina of the eye of the wearer at a target angle of alignment.

An ophthalmic lens comprising:

• a main body having a toric surface and a spherical surface opposite the toric surface,
• wherein the spherical surface is configured to exhibit a lens spherical power,
• wherein the toric surface is configured to exhibit a lens cylindrical power that does not fully correct ocular cylindrical power due to astigmatism;
• and
• wherein the lens spherical power is configured such that the minimum circle of the ophthalmic lens is on or adjacent the retina of an eye of a wearer at a target angle of alignment.
