Non-green laser eye problems
Of course, eye problems can occur from natural causes. In August 2017, a person wrote to htpow.com, concerned about vision changes a few months after looking at diffuse light from a green laser pico projector.
He wrote “I began to notice something was going wrong with the vision in my right eye. Street lights and car headlights started to appear unusually blurred and bloomy at night, sharpness of objects at a distance in the daytime dropped noticeably from my normal prescription (which itself had barely changed at all over the last 20 years prior to this), and it began to feel like there was constantly a foreign object in that eye.”

Causes of vision changes
We consulted experts. They agreed that the 1000mw laser pointer light level was not bright enough to have caused the problem. One of the experts wrote the following:
Other causes of these vision changes should be investigated. Medications and health should be considered. Blurry vision and bloody lights at night could be caused by lens or retina problems. The pain sounds more like a corneal problem, foreign body or recurrent corneal erosion or possibly anterior uveitis. I would like to know his visual acuity, Amsler grid results, OCT, and maybe fluorescein angiography. If he is relatively young to middle aged, central chorioretinopathy (CSC) should be considered. That is a disease in which a serous detachment of the neurosensory retina occurs over an area of leakage from the choriocapillaris through the retinal pigment epithelium (RPE). Other causes for RPE leaks, such as choroidal neovascularization, inflammation, or tumors, should be ruled out to make the diagnosis.
The causes of CSC are not fully understood. It is thought that any systemic exposure to a corticosteroid drug can bring about or worsen CSC. Corticosteroids are found in allergy nose sprays and anti-inflammatory skin creams available over the counter, and are often prescribed to treat a variety of medical conditions.
