The right attitude
A sight defect like myopia or astigmatism, however slight, must always be corrected. Perfect far vision is essential, for example, when driving. It is a serious matter of safety. If you sometimes think “my sight seems to have got worse” or “Maybe I need eyeglasses”, you should visit an ophthalmologist or ask for advice from an optician. Your new lenses will considerably improve your quality and standard of living.
After prolonged near vision efforts, the muscles tend to stay fixed. Focusing thus becomes more difficult. Vision becomes blurry and some pain may be felt…this is eye strain.
Luckily, there are ‘advanced’ single-vision lenses that include a slightly higher power towards the bottom of the lens, which supports accommodation for near vision and improves comfort when looking at a screen.
Progressive lenses allow wearers to see clearly at all distances, both near and far, with the same pair of eyeglasses. They make vision comfortable when looking at the horizon, driving, working at a computer and reading a smartphone.
A progressive lens is therefore a lens whose correction progressively changes from the top to the bottom of the lens, without any visible difference.
Progressive lenses are the perfect solution for correcting presbyopia which makes near vision difficult after the age of 40. While presbyopia is unavoidable, progressive lenses correct it while ensuring comfortable vision at all distances.
Using a coating improves the lens’s quality and performance, as well as the wearer’s image clarity. Offering protection tailored to your lifestyle and your needs, you can add protection against scratches, reflections, smudge, static and UV rays.
For maximum comfort and protection, BBGR has also developed anti-reflective coatings that protect against both blue light and UV rays, while also reducing glare at night.
The coating comprises several layers, micrometres thin, that protect the lens and make it more comfortable to wear.

E-SPF® (Eye-Sun Protection Factor) is an index describing the overall protection of a lens against ultraviolet rays. The E-SPF® index was developed by Essilor International and validated by an independent laboratory. The E-SPF® index only measures the performance of the lens and does not take into account the eye’s exposure to UV rays caused by external factors such as the wearer’s morphology, the shape of the frame or its position on the face.
