Why choose protective sunglasses?
Wearing sunglasses is not just a matter of fashion or aesthetics: their main function is to protect the eyes. Choosing a quality pair of sunglasses means paying attention to details that are fundamental to eye health .
How to recognize quality sunglasses
When we buy sunglasses, we must ensure that they carry the European quality mark “ CE ”. This guarantees that the lenses filter solar radiation (UV and infrared) and that the frame is hypoallergenic. Other factors to consider include:
- Color and intensity of lenses, based on age and visual defects
- 100% UV protection, especially for children
- Ergonomic and safe frames
For this reason, it is essential to contact a qualified optician in a specialized shop, avoiding stalls, markets or uncertified retailers.
The risks of non-approved sunglasses
Buying uncertified sunglasses can cause serious problems, including:
- Early cataract
- Keratitis (corneal inflammation)
- Conjunctivitis (inflammation of the conjunctiva)
- Dry eyes
- Discomfort, dizziness and headaches
These lesions are progressive and often appear late, making prevention with approved sunglasses essential.
The function of sunglasses
The primary job of sunglasses is to filter ultraviolet (UV) and infrared radiation , reducing glare for clear, comfortable vision. A dark lens without UV protection can be even more harmful than a clear one: it dilates the pupil, letting more harmful rays through. A professional optician can recommend the most suitable lenses, considering the specific needs of each eye.
Sunglasses for Kids: Essential Protection
50% of UV radiation we are exposed to occurs before the age of 18. For children, dark lenses with 100% UV protection , preferably polarized, and an ergonomic silicone frame are recommended from 3 months of age. Without adequate protection, risks include:
- Short term: keratitis, eye burns (pain, photophobia, redness)
- Long-term: Corneal degenerative lesions and permanent retinal changes
Lens color and vision defects
The color of the lenses should be chosen based on the visual defects:
- Brown lenses : ideal for short-sighted people, relaxing and with good protection from intense light
- Gray-green lenses : recommended for hyperopic people, they 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 very cheap products: a low price often means sacrificed quality. Non-approved sunglasses not only do not protect, but can also promote the onset of permanent eye diseases .
