Why do glasses with the same prescription feel different?
The old glasses 'remodeled' your eyes. Sometimes, all data on optometry and processing are accurate, and the spectacles equipped are in full compliance with the prescription for optometry, or the power of new spectacles is exactly the same as that of the old spectacles, but you will still be dizzy when wearing the new spectacles. This is because the old glasses 'remodeled' their eyes during long-term wear. For example, the old glasses used by some people have been severely deformed. The temples are no longer in the same plane, and the optical center area of the lens will deviate from the interpupillary distance measured by the glasses at that time. However, the wearer does not mention this situation, and the eyes gradually adapt to this kind of deviation. After putting on a new pair of glasses, you will not adapt to them.
How to protect your contact lenses?
When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.
What Are Progressive Lenses?
Traditional eyeglasses are usually single vision lenses with one prescription. Progressive lenses are multiple with three prescriptions in a pair of eyeglasses. Progressive lenses let you see comfortably at different distances, allowing you to see close, near, and far without changing your glasses. There are other kinds of multifocal lenses like bifocals and trifocals, but progressive lenses differ because of their smooth transition between prescriptions.
Bifocals and trifocals work similarly to progressive lenses and feature either two or three prescriptions in a pair of glasses. These lenses have definitive lines separating the prescriptions. However, progressive lenses don’t use these lines and allow you to easily transition between prescriptions.
Hence, in the following section, we will show you 6 different types of progressive lenses.
Are carbon fiber glasses better or titanium?
In terms of weight, the titanium frame is very light. The specific gravity of the pure titanium frame is about 4.5g/cm3, and the specific gravity of the titanium alloy frame is about 8.9g/cm3. The pure titanium frame is lighter than the titanium alloy frame. However, carbon fiber glasses are lighter in weight. The carbon fiber glasses launched by LOHO are only 7.87g, which is very light to wear.
In terms of hardness, titanium has a high hardness, about twice that of stainless steel, twice that of iron, and six times that of aluminum. Carbon fiber is lighter than aluminum, harder than steel, and its strength is ten times that of iron.
In other respects, the titanium frame has the advantages of corrosion resistance, acid and alkali resistance, high stability, good elasticity, good toughness, and resistance to deformation. The carbon fiber frame has the advantages of corrosion resistance, high temperature resistance, radiation resistance, good elasticity, good flexibility, and abrasion resistance.
It can be seen from the above comparison that carbon fiber glasses have the general advantages of titanium frames. In terms of weight, carbon fiber glasses are much lighter than ordinary pure titanium glasses.
Tortoiseshell glasses have many benefits.
Tortoiseshell glasses are made from the only sea turtle on the earth that can digest the glass material, and its sea turtle is the country's most precious wildlife, which is of great value. Wearing tortoiseshell glasses will not easily slip off even if you sweat and will not produce allergic symptoms. Tortoiseshell is so strong that it will not break even when the frames are bent to 45 degrees and will not be deformed throughout the year. In addition, the stability of the tortoiseshell is good.
What Should You Do If Your Glasses Are Broken?
Professional eyewear repair shops have professional repair tools. It's relatively easy to fix the bent frame by yourself. Still, there are reasons to get a professional to fix them. Your local eyewear repair shop can quickly reshape metal and plastic frames and make sure they fit. Many professional optical shops will make small adjustments free of charge. The frame is completely broken and requires special tools and skills to fix. Frames are too fragile to repair at home, and trying to do so could cause even more damage to your frames. The lenses are damaged and you may need to replace them. Make sure your prescriptions are up to date. If your prescription is not up to date, you need to schedule an eye exam before changing your lenses.
