Why choose protective sunglasses?
Wearing sunglasses is not just a matter of fashion or aesthetics: their main function is to protect your eyes. Choosing a pair of quality sunglasses means paying attention to fundamental details for eye health.
How to recognize quality sunglasses
When buying sunglasses, we must ensure they bear the European quality mark "CE". This guarantees that the lenses filter out solar radiation (UV and infrared) and that the frame is hypoallergenic. Other factors to consider include:
- Lens color and intensity, based on age and visual defects
- 100% UV protection, especially for children
- Ergonomic and safe frames
For this reason, it is essential to consult a qualified optician in a specialized store, avoiding stalls, markets, or uncertified retailers.
The risks of non-approved sunglasses
Buying uncertified sunglasses can cause serious problems, including:
- Early cataracts
- Keratitis (corneal inflammation)
- Conjunctivitis (inflammation of the conjunctiva)
- Dry eyes
- Discomfort, dizziness, and headaches
These injuries are progressive and often manifest late, making prevention with approved sunglasses essential.
The function of sunglasses
The main task of sunglasses is to filter out ultraviolet (UV) and infrared radiation, reducing glare for clear and comfortable vision. A dark lens without UV protection can be even more harmful than a clear one: it dilates the pupil, allowing more harmful rays to pass through. A professional optician can recommend the most suitable lenses, considering the specific needs of each eye.
Sunglasses for children: essential protection
50% of the UV radiation we are exposed to occurs before the age of 18. For children, a dark lens with 100% UV protection, possibly polarized, and an ergonomic silicone frame from 3 months of age is recommended. Without adequate protection, risks include:
- Short term: keratitis, ocular sunburn (pain, photophobia, redness)
- Long term: degenerative corneal lesions and permanent retinal alterations
Lens color and visual defects
Lens color should be chosen based on visual defects:
- Brown lenses: ideal for myopia, restful and with good protection from intense light
- Grey-green lenses: recommended for hyperopia, do not distort colors and reduce glare
Both offer excellent protection without altering color perception, but the choice must be guided by an expert.
Tips for a safe purchase
To protect your eyes, only trust a trusted optician. Avoid counterfeit or overly cheap products: a low price often means compromised quality. Non-approved sunglasses not only do not protect, but can promote the onset of permanent eye conditions.
