Dought & clear, - Ruling on prostrating when wearing glasses.

As a muslim,are we allowed to perform our salaat while wearing
coloured contact lens? or glasses?.
Praise be to Allaah.
There is nothing wrong with praying when wearing coloured contact
lenses or glasses, unless the glasses prevent the worshipper from
placing his nose or forehead firmly on the ground when prostrating. In
that case he has to take them off before he prays or when he
prostrates.
Al-Bukhaari (812) and Muslim (490) narrated that Ibn 'Abbaas (may
Allaah be pleased with him) said: The Prophet(peace and blessings of
Allaah be upon him) said: "I have been commanded to prostrate on seven
bones: the forehead" – and he pointed to his nose – "the hands, the
feet and the ends of the feet (i.e., toes)"
Shaykh Ibn 'Uthaymeen (may Allaah have mercy on him) was asked about
the person who wears large glasses, which prevent him from being able
to prostrate fully on the seven parts of the body.
He replied:
If they prevent the end of the nose from reaching the ground when
prostrating that is not acceptable, because what is carrying the face
in this case is the glasses, which are not at the end of the nose,
rather they rest on the bridge of the nose. Based on this, the
prostration is not valid. The one who wears glasses that prevent him
from placing his nose in the place of prostration has to take them off
when prostrating. End quote fromMajmoo' Fataawa al-Shaykh Ibn
'Uthaymeen(13/186).
And Allaah knows best.
