Sunshades are a type of protective eyewear intended to keep bright sunlight and high-energy visible light from harming or irritating the eyes. Sunglasses or goggles with coloured, angled, or darkened lenses, also known as spectacles or shades, may also be used as a visual aid. By shielding the eye from glare, sunglasses will enhance visual comfort and visibility. After receiving mydriatic eye drops during eye tests, patients are given a variety of disposable sunglasses.

Polarized sunglasses lenses suppress glare reflected from non-metallic surfaces, such as water, at certain angles. Medical experts advise the public to wear sunglasses to shield one’s eyes from UV rays; sunglasses that mirror or block out 99 per cent or more of UVA and UVB light with wavelengths up to 400 nm are recommended for adequate protection.
In fact, according to Optometry Australia’s 2020 Vision Index data, 76 per cent of Australians believe that wearing sunglasses in the winter is unnecessary. Not only that, even 10% of people are unaware that UV-protective eyewear is available.

But how do they work?
Sunglasses shield the eyes by reflecting UV rays and serving as a barrier. Sunglasses are the outerwear equivalent of sunscreen. They shield the eyes from the sun’s ultraviolet light rays as well as being a beach decoration. Shades can shield the eyes from at least 99 per cent of UV rays, according to experts. The sun’s rays can enter the eyeball from various areas. UVA rays can enter the retina in the back of the eye, while UVB rays can still reach the cornea in the centre. Sunglasses block these rays from entering the eye, preventing possible damage and vision loss.
Risks caused by UV exposure:
UV rays are dangerous to the eyes because they can cause both short and long-term vision issues. If individuals don’t have a pair of sunglasses on hand, they might be at risk for the following health problems.
SHORT TERM RISKS:
- Swollen eyes
- Bloodshot eyes
- Light hypersensitivity
LONG TERM RISKS:
- Cataracts
- Macular Degeneration
- Pinguecula
- Eye cancer
- Photokeratitis
Reasons to Wear Sunglasses?
Nonetheless, this simple and stylish accessory* will protect eyes from a variety of UV-related conditions, including:
- Skin cancer
The eyelids are home to up to 10% of all skin cancers.
- Cataracts
According to the World Health Organization, nearly 900,000 people are blind due to cataracts, which are cloudiness in the eye’s lens caused by UV exposure.
- Pterygium
This abnormal tissue development, also known as the surfer’s eye, can progress slowly from either corner across the white part of the eye, causing inflammation or vision disturbance.
Although non-tinted glasses are rarely worn for purposes other than correcting vision or shielding one’s eyes, sunglasses have grown in popularity for various reasons and are now worn even indoors or at night.
It’s just not the $5 pair on the corner. Those are more likely to cause trouble than good. Because pupils dilate when one wears dark lenses, cheap sunglasses will let more harmful rays into the eyes than if we didn’t wear any at all. Look for men’s sunglasses in Australia that block 99 to 100 per cent of UVA and UVB rays. With the right pair of sunglasses, individuals can protect their eyes while still looking fine. It’s important to wear their favourite pair as much as possible outside if one even has several styles for different occasions.
