Avoid using shortcuts within an essay. Instead, write out the full name of the policy or guideline. Examples: "AGF in NPOV disputes" instead of "assuming good faith in neutrality disputes" "articles need RS as per WP:BIO" instead of "articles need reliable sources as per Wikipedia's guidelines on biographies" Avoid writing essays that are too ...
Near-sightedness is due to the length of the eyeball being too long; far-sightedness the eyeball too short; astigmatism the cornea being the wrong shape, while presbyopia results from aging of the lens of the eye such that it cannot change shape sufficiently. [3] Some refractive errors occur more often among those whose parents are affected.
Against-the-rule astigmatism – the horizontal meridian is steepest (a rugby ball or American football standing on its end). [17] Oblique astigmatism – the steepest curve lies in between 120 and 150 degrees and 30 and 60 degrees. [17] Irregular astigmatism – principal meridians are not perpendicular.
Astigmatism can be often corrected by glasses with a lens that has different radii of curvature in different planes (a cylindrical lens), contact lenses, or refractive surgery. [5] Astigmatism is quite common. Studies have shown that about one in three people suffers from it. [6] [7] [8] The prevalence of astigmatism increases with age. [9]
In order to determine if the patient has astigmatism at a particular meridian, the -0.50 JCC is presented at the following axes: 90°, 180° and then check the oblique axes at 35° and 145°. [ 6 ] As the JCC is a combination of two cylindrical lenses, any cylindrical power that is added must be accompanied by a spherical lens equivalent, to ...
For example, 2025 RMDs must be completed by Dec. 31, 2025. However, there's an exception for your first RMDs. Those who turned 73 last year have until April 1, 2025, to take their first RMD.
For example, using equity for energy-efficient upgrades could lower utility bills, while aging-in-place modifications could help avoid costly assisted living expenses down the road.
In some types of writing, repeated use of said is considered tedious, and writers are encouraged to employ synonyms. On Wikipedia, it is more important to avoid language that makes undue implications. Said, stated, described, wrote, commented, and according to are almost always neutral and accurate. Extra care is needed with more loaded terms.
