Snow Blind.
Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense direct or reflected sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva.
The injury may be prevented by wearing eye protection that blocks most of the ultraviolet radiation, such as welding goggles with the proper filters, a welder's helmet, sunglasses rated for sufficient UV protection, or appropriate snow goggles. The condition is usually managed by removal from the source of ultraviolet radiation, covering the corneas, and administration of pain relief. Photokeratitis is known by a number of different terms including: snow blindness, arc eye, welder's flash, sand eyes, bake eyes, corneal flash burns, flash burns, niphablepsia, or keratoconjunctivitis photoelectrica.
Oil spots on the sensor of Nikon D7000 series cameras became a notable issue shortly after the model's release. These spots were caused by oil from the camera's internal mechanisms, particularly the shutter or mirror assembly, being dispersed onto the sensor. This resulted in visible smudges or dark spots in images, especially noticeable in shots with large areas of sky or uniform backgrounds. The oil spots were more prevalent in new units and tended to decrease over time, though some users experienced persistent problems. While Nikon did not officially issue a recall, they offered cleaning services for affected cameras, and many users resorted to DIY cleaning methods or professional sensor cleaning to address the issue. (Not for me ! several cleaning sessions 2 professionally and they still show. I have owned the D7000, D7100, D7200 and all suffered the same problem to some extent). It ruined my Nikon experience forever.
