The matter is actually greater than that, but it is not that difficult either. Buying sunglasses depends on 10 rules that you must make sure of so that the glasses you bought are the right glasses in terms of eye protection, comfort, shape, size, size and quality, do not worry! Here are the simple rules.
10 – 100% UV rays protection
Sunglasses must ensure maximum protection from the harmful ultraviolet rays that emit from the sun’s UV rays. Although 99% of these rays do not reach the earth, the 1% of them that succeed in reaching can cause a lot of damage, The main ones are:
- Blurred vision, which occurs on prolonged exposure to ultraviolet rays.
- Damage to the retina that leads to macular degeneration.
- The change in the direction of the eyeball as a result of an abnormal growth of tissue in the white part.
- Skin diseases, including cancer.
So when buying sunglasses, it is necessary to make sure that they guarantee protection from these rays by reading the attached description and choosing the original lenses.
9- Sunscreen lenses – Polarization lenses
Not all types of glasses provide this feature, so when buying sunglasses it is necessary to make sure that polarized lenses are available, why? Because it reduces glare and thus guarantees clearer vision and more protection when the sun’s rays are very strong, as is the case on the beach or in places of snow or on the sand so that the sun reflects and doubles its glare.
8 – The bigger the sunglasses the better
The harmful UV rays not only affect the eyes, but also destroy the skin and this is what makes larger glasses the best glasses, but this does not apply to all glasses, but only those that guarantee protection from harmful rays in order to ensure coverage and protection for each area. The eye and the surrounding skin.
7 – Darker or more colored glasses do not mean more protection
If the lenses are colored or darker to a greater degree does not mean that they are better on the contrary, in the event that the lenses are not able to block the UV rays of the sun, these lenses will be dangerous, why?
Because it will be easy to look at the sun directly without feeling any effect of its glow or pain, which increases the possibility of damage to the retina (pain and discomfort when looking at the sun is important in preventing prolonged looking at it and thus protecting from its harmful rays).
6 – It doesn’t have to be expensive
When buying sunglasses, choosing the lenses that guarantee the highest degree of protection and preventing glare does not mean at all to pay huge sums, as good glasses are at an affordable price and most of the time the additional cost is due to the distinctive and exclusive design, the expensive brand or the materials from which the frame of the glasses is made.
5 – The size and shape of the eyeglass frame
When it comes to buying sunglasses, the options are very many and varied, depending on the shape of the frame and its size, and it all depends on choosing the right frame for your face shape. If your face is thin, then rely on the smooth frame, but if your face is full, you can rely on larger frames.
With regard to frames, you can distinguish 3 basic dimensions that you must check when buying sunglasses, namely:
- Eye size
It is the lens distance, i.e. the distance between the inner and outer corner of only one lens, which must cover your entire eye and surround it with a somewhat equal distance from all sides, and the lens distance is usually 40-60 millimeters.
- Bridge size measurement
The eyeglass bridge is the distance between the two inner corners of the eyeglass lenses, and you should choose it so that it is suitable for the glasses to rest on your nose, and is usually between 14 – 24 millimeters.
- Temple size arm
It is the length of the eyeglasses arm, which must be proportional to the dimension of your ear so that the glasses are placed and lean on, and this distance usually ranges between 120-150 millimeters.
