If you have astigmatism, your cornea is shaped wrong, so your lenses may be more like a cylinder. Simply put, the lens is a tool you use to focus light onto your retina in the correct way.

Praise be to Allaah. There is nothing wrong with ending a letter with the phrase âwaâl-salaam,â and it is not a condition that the phrase should be used in full, because when a written abbreviation is used, what the writer means is the complete expression.aâl-salaam.â However, the person sending the letter should greet the addressee with the complete phrase (âAl-salaamu alaykumâ) at the beginning of the letter, as has been the habit of the Muslims from the time of the Prophet SAWS (peace and blessings of Allaah be upon him) until the present.
