Cheap sunglasses may not block UV rays, potentially causing eye damage.
The claims regarding cheap sunglasses and their UV protection capabilities are mostly supported by the evidence. Cheap sunglasses often lack proper UV protection, which can lead to eye damage. This is corroborated by multiple sources, including Lensmart, NVISION, and Ramsey EyeCare, which emphasize the importance of UV400 labeling for effective protection. The claim that cheap sunglasses only block visible light is also supported by evidence indicating that many do not block UV rays. The assertion about the retina being damaged by UV light is confirmed by sources like Retina Consultants of Nevada, which describe solar retinopathy as a risk. However, the claim that plastic glasses do not block UV rays is misleading, as some plastic glasses do offer UV protection if properly labeled. Overall, the claims are mostly factual with some nuances.

Cheap sunglasses are worse than no sunglasses.
This claim is an opinion and cannot be definitively proven true or false. However, evidence suggests that sunglasses without UV protection can be harmful, as they may cause the pupils to dilate and allow more UV light to enter the eyes. Sources like Lensmart and NVISION support this view, but it remains subjective.

Cheap sunglasses only block the visible range of light.
Evidence from sources like Martin Eye Associates indicates that many cheap sunglasses do not block UV rays, only visible light. This supports the claim, but it is not universally true for all cheap sunglasses.
In the sun, the diaphragm of the eye expands and the retina burns out with ultraviolet light.
The claim is supported by evidence from Retina Consultants of Nevada and Neoretina, which describe solar retinopathy as a risk from UV exposure. This supports the claim that UV light can damage the retina.
