Omneya won the World Junior Championship in Egypt 2003. Omneya crowned a sparkling junior career in 2003 in her home city of Cairo when she lifted the World Junior title after having been the runner up to Nicol David in 1999 and 2001. Such was her precocious talent that she was already competing on the WISPA Tour in her mid teens. Her success has been amply evidenced by her having already reached a high of seven in the world rankings earlier in 2005.
The highlight of 2005 was reaching match ball against world number one Rachael Grinham in the final of the Hurghada International in her home country though she eventually lost the match. She also reached another two finals, in Greenwich and Dayton, both in the United States, and finished as a runner up. Omneya then won the Marsh McLennan title by beating Vicky Botwright. Since then she has continued to be a threat to all the top players, her astute tactical brain and range of shots causing problems to everybody she meets.
2006 saw Omneya avenged the Hurghada loss the previous year when she turned the tables in a pulsating Hurghada final to win the event in front of ecstatic home supporters.
Recently, she won the 2007 EBS Dayton Open by beating Jaclyn Hawkes of New Zealand with a score of 9–5, 9–5, 3–9 and 9–5.
