Like any other virus, can be transmitted via conjunctiva. So necessary precautions must be taken.
I agree Rabin Thapa, the oxygen that is able to passively diffuse into the body directly from the air into the eye is possibly a media for entry of virus via aerosol media

According to WHO conjunctivitis is one of the symptoms of people with COVID 19.
If I want to go into more detail, the virus can infect conjunctiva, which covers the inside part of eyelids and white part of your eyes. it is also called pinkeye (Red, Swollen and Itchy eyes)
Yes it's possible. Something that we have to keep in mind about conjunctivitis is that it has been found as a symptom of COVID-19 in very low percetages of diagnosed patients.

Article The ocular surface, coronaviruses and COVID ‐19
Not in a scary way but few conjunctivitis has been reported. Spreading through tear film is also limited as observed by studies before.
Yes, most probably. Ocular surfaces may be a plausible route of transmission. Viral conjunctivitis has also been reported in about 1 to 3% of infected cases, as an external ocular manifestation of COVID-19. Beside this, some authors have also reported ocular lesions including retinitis and optic neuritis as a COVID-19 neurological events. Further descriptions have been given in the attachment below. Hope it helps!
There is no doubt on ocular involvement in COVID-19. Most of cases present with conjunctivitis as our experience. Epiphora, chemosis, lid edema, follicles etc are common signs. But studies have shown that it doesn’t spare posterior segment of eyes. As mentioned in earlier answers, retinitis, optic neuritis have also been reported in some cases.
Unilateral/bilateral occurences have been reported.
Many research papers have been published on Ocular manifestation of COVID.
In Nepal, no articles are yet published on ocular manifestation, hope we get one soon.

Covid-19 being a respiratory tract illness, it has various extrapulmonary manifestations not sparing eye at all, though incidence is very minimal and patient most commonly presents as anterior segment findings in the form of viral conjunctivitis (pink eye) with redness, discomfort, swelling and itching which might be either unilateral or bilateral and laterality depend on the contamination as by now we all are aware of the mode of transmission from person to person via respiratory droplets is believed to be primary method and transmission may potentially occur through the ocular route with the incidence of 0.8 to 1 % only. One should be very critical about the proper differential diagnosis as other forms of conjunctivitis also has similar presentation and history of fever, dry cough, fatigue, shortness of breath, sore throat, myalgia along with chills needs to be taken care of for clinical diagnosis.
Posterior segment manifestation in the form of retinitis and optic neuritis has been reported with details to follow.
Yes. Conjunctivitis can be caused due to Covid-19 virus. Tears contain Corona virus, so its mandatory to was your hands with soap and water after examining each patient or change gloves in between patients. Doctors should protect their eyes, nasal cavity and throat getting contaminated by wearing a face shield.
Yes, COVID-19 can infect the eye.

Article COVID-19: Ophthalmological Aspects of the SARS-CoV 2 Global Pandemic
There is information that doctors with strict use of mask and gloves, have contracted the virus, and claim that they were infected through the mucosa that covers the white part of the eyes. Hence, many people prefer to use the face shield since it covers the entire face.
