DRDO Anti-Radiation Missile DRDO Anti-Radiation Missile The DRDO Anti-Radiation missile is a tactical, air-to-surface anti-radiation missile under development by India's Defence Research and Development Organisation. It is designed primarily to destroy enemy radars and communication facilities. This is a state-of-the-art air-to-surface anti-radiation missile being developed by Defence Research and Development Laboratory of the DRDO. The range of the missile is believed to be 100–125 km and it will be mounted on the combat aircraft of the IAF such as Sukhoi Su-30MKI and Tejas Light Combat Aircraft. The entire missile is being developed indigenously, including the seeker. According to the then Director of RCI,
Subjective refraction reliability of subjective refraction is high. However, it comes with advantages and disadvatages. Subjective refraction Subjective Refraction is an attempt to determine, by trial and error using the patient’s cooperation, the combination of lenses that will provide the best corrected visual acuity (BCVA). It is a clinical examination used by orthoptists, optometrists and ophthalmologists to determine a patient's need for refractive correction, in the form of glasses or contact lenses. The aim is to improve current unaided vision or vision with current glasses. Glasses must also be comfortable visually. The sharpest final refraction is not always the final script the
