Gimblett continued the good work of Claud Worth FRCS in the treatment of strabismus in children, and did more than anyone else to promote a wide public interest in the use of orthoptic eye-exercises for this purpose. He was the first chairman of the Orthoptic Board when it was established in connection with the British Orthoptic Society and the Board of Registration of Medical Auxiliaries established by the British Medical Association in 1933. From 1937 to 1956 he was ophthalmic surgeon to the Lord Mayor Treloar's Orthopaedic Hospital at Alton. He was a vice-president of the Ophthalmology Section in the Royal Society of Medicine. He worked during the war of 1939-45 at Haymeads Hospital, Bishop's Stortford, Herts, and was elected ophthalmic surgeon to the town's General Hospital there, and was also for a time at Saffron Walden, Essex. Gimblett married in 1935 Audreen Isobel McKenzie, daughter of Duncan McNicol, who survived him with their two sons. He died in the Westminster Hospital on 21 January 1957 aged 66. The funeral was at Newport Pagnell parish church, and a memorial service was held at St Giles in the Fields WC2 on 8 February. He formed a good collection of books on mediaeval art, and was a connoisseur of antique furniture. His favourite recreation was sailing, when taking his holiday in the Mull of Kintyre.
