TECHNICAL FIELD
[0001] The present disclosure relates to the field of assistive device for handling optical lens. In particular, the present disclosure provides a handheld device for facilitating insertion and removal of contact lens into/from a user’s eyes.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.
[0003] Wearing and taking off contact optical lenses can be challenging to some users. Some people with ophthalmic problems fear that finger nails can harm their eyes or dust and other particles may enter into the eyes while inserting the lens into the eyes. Some users are afraid that the act of putting on the contact lenses may cause damage to sensitive parts of the eyes. Therefore it would be beneficial to develop a device that can be held by a user’s hand, the device being used to assist insertion and removal of contact lenses to/from the user’s eyes.
[0004] Existing literature describes a contact lens applicator having robotic arm to grasp the contact lens and delivering to eye of a user. Another contact lens applicator has been configured to have motorized gripper for opening the user’s eye and inserting the contact lens. An assembly for contact lens insertion and remover has been discussed in another prior-art, where the apparatus facilitates supporting tissues surrounding the eye of the user. Another literature describes a deformable concave structure for grasping the contact lens, the deformable structure being configured to pinch the contact lens for removal from and insertion into the user’s eye. However none of the disclose devices describe a device for contact lens insertion and removal that can interact with the user and provide assistance in controlling alignment of the device with respect to the user’s eyes.
[0005] The proposed device is configured to be held by the user’s hand and facilitate insertion and removal of contact lens into and from the user’s eyes. The device is configured to have interactive feature for receiving user inputs and generating notifications. Alignment of the device with respect to the user’s eyes may be automatically corrected based on user’s inputs. A lens holding unit of the device is enabled to grasp the contact lens prior to application and post removal, the lens holding unit being enabled to perform a set of movements based on user inputs. The proposed device is configured to be powered by one or more power generation units, the charge status being displayable for user interaction.
