TL;DR: Mr Mfazo Hove, consultant ophthalmic surgeon and founder of Blue Fin Vision®, has shared practical sunglasses advice with Yahoo Style UK. He identifies five mistakes that can compromise UV protection, including relying on dark lenses, judging protection by price and choosing frames with insufficient coverage.
Making a Better-Informed Choice
With sunglasses available in a wide range of styles and prices, it can be difficult to know which features genuinely protect the eyes.
Yahoo Style UK asked Mr Hove to explain the most common mistakes shoppers make and what they should consider instead.
Do Not Judge Protection by Tint
A dark lens may feel comfortable in bright conditions because it reduces visible light. However, the tint does not confirm whether the lens filters ultraviolet radiation.
Mr Hove explains:
“UVA and UVB rays are not on the visible spectrum, so you can’t see them.”
This means two pairs of sunglasses with a similar tint could offer different levels of UV protection.
Find Evidence of UV Protection
Mr Hove recommends looking for UV400 information and other recognised protection markings before buying. These details may be printed on the packaging rather than the sunglasses themselves.
Where the information is unclear, shoppers should ask for assistance or choose another retailer that can confirm the protection offered.
Separate Price From Performance
Paying more for sunglasses may provide a particular brand, frame material or design, but it does not automatically provide better UV filtering.
Mr Hove’s advice is to assess protection on its own merits. A reasonably priced pair with verified UV protection and an appropriate fit may be a better choice than expensive sunglasses that offer limited coverage.
Make Sure the Frames Fit
The frame should remain secure without sliding down, pinching or leaving excessive gaps. A suitable fit helps reduce the amount of light reaching the eyes and the delicate skin around them.
Optometrists can often adjust frames so that they sit more comfortably and provide more consistent coverage.
Consider Lens Size and Shape
Mr Hove advises shoppers to consider the upper and lower eyelids as well as the sides of the eyes. Larger lenses and wraparound frames generally block more light from reaching these areas.
The most suitable design will depend on the wearer, their activities and the environment in which the sunglasses will be used.
